In industries such as steel fabrication, metal processing, construction, and machinery manufacturing, the storage of long and heavy materials including steel pipes, tubes, bars, and profiles presents significant challenges. Conventional storage methods often require large floor areas, create difficulties in material access, and increase safety risks during handling. Herochu’s heavy-duty cantilever racking systems provide a professional storage solution designed specifically for long, oversized, and heavy industrial materials, improving warehouse organization, accessibility, and operational efficiency.

Herochu industrial cantilever racks are engineered to safely store steel pipes and other long materials with maximum stability and flexibility. Unlike traditional pallet racks, cantilever storage systems use a column-and-arm structure without front support columns, allowing operators to easily load and unload materials from the front side. This open design makes the system ideal for storing irregular, extra-long, or heavy products that cannot be efficiently handled by standard shelving systems.

The heavy-duty structure is manufactured using high-strength steel components, providing excellent load-bearing capability and long-term durability in demanding industrial environments. Reinforced columns, horizontal bases, and adjustable cantilever arms ensure reliable support for different sizes and weights of steel pipes, tubes, profiles, and metal materials. The modular design allows storage capacity and rack dimensions to be customized according to specific warehouse layouts and customer requirements.

One of the key advantages of Herochu cantilever racking systems is their high flexibility. The adjustable arms can be configured to accommodate various material lengths and diameters, making the system suitable for diverse applications such as steel pipe storage, aluminum profile storage, timber storage, mechanical parts storage, and construction material management. Whether storing lightweight tubes or several-ton industrial steel products, the rack structure can be customized to achieve optimal performance.

The double-sided cantilever rack design further improves warehouse utilization by allowing access from both sides. This configuration increases storage density while maintaining convenient operation, making it an excellent choice for warehouses with high inventory turnover and limited floor space. By organizing long materials vertically and efficiently, companies can reduce clutter, improve workplace safety, and create a more streamlined storage environment.

Safety is a major consideration in industrial material storage. Poorly stacked steel pipes and manually arranged long materials can easily cause rolling, falling, or handling accidents. Herochu cantilever racks provide stable storage positions that keep materials securely organized and reduce potential workplace hazards. Optional safety accessories, protective components, and customized structural solutions can be added according to different operating conditions.

The system is suitable for a wide range of industries, including steel processing plants, metal manufacturing facilities, automotive suppliers, engineering workshops, logistics centers, and construction material warehouses. Its simple structure, strong load capacity, and easy accessibility make it an effective solution for companies seeking to optimize long material storage and improve warehouse management.

Herochu provides customized cantilever racking solutions based on customers’ material specifications, storage requirements, and facility conditions. From rack height, arm length, load capacity, and column configuration to surface treatment and additional safety features, every system can be designed to meet specific industrial needs.

More than a storage rack, Herochu heavy-duty cantilever racking systems represent a practical upgrade for modern industrial logistics. By combining strength, flexibility, safety, and efficient space utilization, these systems help manufacturers and warehouses achieve better inventory control, faster material handling, and improved operational productivity.

Industrial pipe storage has long been plagued by a fundamental contradiction: the need to store long, heavy materials efficiently while maintaining quick, safe access. Floor stacking consumes vast square footage, creates safety hazards, and turns material retrieval into a labor-intensive treasure hunt. Static cantilever racks improve organization but still force operators to navigate around fixed arms that block access to rear inventory.

Herochu has engineered a solution that resolves this contradiction at its core. The Heavy Duty Telescopic Cantilever Rack for Pipe Storage represents a paradigm shift in how warehouses, metal service centers, and fabrication shops manage their pipe inventory. Rather than forcing materials into static configurations, this system brings the storage to the operator through full-extension telescopic arms that roll out 100% into the aisle.

Structural Foundation Built for Heavy Loads

Every Herochu telescopic cantilever rack begins with a robust steel framework designed to withstand the demands of continuous industrial use. The upright columns are available in heights ranging from 2000mm to 9000mm, accommodating facilities with varying ceiling clearances and storage density requirements. Column heights of 6000mm, 7000mm, and 9000mm enable vertical storage strategies that dramatically increase capacity per square foot of floor space.

The arm configuration offers exceptional flexibility. Standard arm lengths of 1000mm and 2000mm serve as the foundation, with custom extensions available up to 3000mm to accommodate wider pipe diameters and bundled loads. Each arm supports between 0.5 tons and 3.0 tons, depending on the specification, with per-layer load capacities that can be customized to match specific inventory profiles.

The interlocking fixed arm structure delivers strong anti-fatigue and anti-impact performance, resisting deformation and damage under long-term heavy loads. This structural integrity translates directly into extended service life and reduced maintenance costs over the operational lifetime of the rack.

Telescopic Technology That Transforms Access

The defining feature of Herochu’s heavy duty telescopic cantilever rack is its roll-out mechanism. Each tier of arms mounts on precision-ground rollers and hardened rails, allowing smooth extension and retraction even under full load. Operators can choose between manual hand crank operation or motorized electric drive, depending on throughput requirements and load weights.

The electric drive system operates on 380V 50Hz 3-phase power and delivers extension speeds of 0.1 to 0.2 meters per second. Touch screen and push-button dual controls provide flexible operation options, while the electric control system ensures safe, stable performance throughout thousands of cycles.

When extended, the cantilever arms expose the entire length of stored pipes to overhead cranes or hoists. This eliminates the need for operators to reach into deep rack structures or maneuver around obstructions, significantly reducing retrieval times and minimizing the risk of material damage during handling.

Space Optimization Through Intelligent Design

Traditional pipe storage methods require wide aisles for forklift access, consuming floor space that could otherwise generate revenue. Herochu’s telescopic cantilever rack changes this equation entirely. The ability to retract arms when not in use reduces the rack’s footprint by 40 to 60 percent, turning a 1500mm arm into a 600mm protrusion.

Narrow aisle requirements mean warehouses can pack more storage capacity into existing buildings. The vertical storage capability of column heights up to 9000mm further multiplies density, allowing facilities to store pipes in multiple tiers without sacrificing accessibility.

The system accommodates pipe materials from 3 meters to 12 meters in length, with customization available for virtually any dimension. This flexibility ensures that Herochu racks adapt to existing inventory rather than requiring inventory to adapt to the rack.

Surface Treatment and Durability

Industrial environments expose storage equipment to moisture, dust, chemicals, and physical impact. Herochu addresses these challenges through comprehensive surface protection. Powder coating and painted finishes are available in blue, black, or white, providing corrosion resistance while maintaining a professional appearance.

For telescopic mechanisms with moving parts, Herochu applies a two-layer protection system: zinc plating on all roller components and slides, plus a powder-coated finish on static structural elements. This combination prevents galling and corrosion while maintaining smooth extension even after years of dusty or humid operation.

Customization for Specific Requirements

No two pipe storage operations are identical. Herochu recognizes this reality and offers extensive customization across every parameter. The number of layers ranges from 2 to 6, with each layer height adjustable to match specific pipe diameters and stacking configurations. Extension length, column height, load capacity, and arm configuration can all be specified according to actual material dimensions and available space.

Double-sided and single-sided layouts provide additional configuration options. Double-sided racks maximize storage density in central aisle configurations, while single-sided designs work effectively against walls or in perimeter locations.

Industry Applications

The Heavy Duty Telescopic Cantilever Rack for Pipe Storage finds application across multiple industrial sectors. Machinery manufacturing facilities use these racks to organize steel tubing and hydraulic piping. Pipe and profile processing operations rely on them for efficient work-in-progress storage. Metal service centers depend on them for inventory management of carbon steel, stainless steel, and aluminum pipe stock.

Construction material suppliers, structural steel fabricators, and oilfield equipment manufacturers all benefit from the organized, accessible storage that Herochu telescopic cantilever racks provide.

A warehouse that stores 6-meter pipe bundles today may need to store 12-meter structural tubing next year and add aluminum extrusion inventory the year after. Fixed-dimension racking forces warehouse managers into awkward compromises — oversized bays for small products waste vertical space, undersized bays for large products create unsafe overhangs, and any change in product mix means buying new racks. Herochu’s adjustable cantilever racking system takes a different approach: build the frame once, adjust the arm positions and layer count as needs evolve, and reconfigure without cutting steel or welding on site.

Adjustability as a Core Design Principle

Most industrial racking ships with fixed arm spacing. The holes are drilled where they are drilled, and if the spacing does not match the product dimensions, the warehouse lives with the inefficiency. Herochu designs adjustability into the column geometry from the start. Columns feature pre-drilled hole patterns at regular intervals — typically every 75 or 100 millimeters along the vertical axis. Arms bolt into any hole pair, which means arm spacing can be set to any increment within the column range.

This adjustability impacts storage density directly. A warehouse storing 50-millimeter diameter tubing can set arm spacing at 500 millimeters center-to-center and fit 8 layers within a 4-meter column. The same column, reconfigured for 200-millimeter pipe, might use 700-millimeter spacing and 5 layers. The rack adapts; the warehouse does not need to buy two different rack types for two different product families.

The base clear space specification starts at 600 millimeters — measured from the top of one arm surface to the bottom of the arm above it. This dimension provides room for standard fork tines or crane slings to enter and exit the compartment without contacting the material above. Warehouses can increase this dimension to accommodate larger diameters or decrease it when storing consistently small products. The adjustment procedure itself takes minutes per arm: unbolt, reposition to the desired hole pair, re-torque the fasteners to specification. No fabrication skills needed.

Modular Frame That Grows With the Warehouse

Herochu cantilever racks assemble from a kit of standard components: base plates, upright columns, cantilever arms, and crossbars. This modularity means the system scales in three directions.

Vertically, a 5-layer HC-G6053 can become a 7-layer rack by adding arm pairs and extending the column height — provided the floor slab and base anchors support the additional weight. Horizontally, new bays bolt onto the end of an existing row by adding a new column-and-arm assembly. The row length grows by one bay at a time, matching the pace of inventory growth rather than requiring an all-at-once capital outlay.

Depth-wise, the choice between single-sided and double-sided configurations determines how many compartments the rack holds. A single-sided HC-G6053S mounts arms on one face of the column — ideal for racks positioned against a wall or used as aisle dividers. A double-sided HC-G6053 mounts arms on both faces, effectively doubling the storage density per linear meter of aisle. Facilities that start with single-sided racks against perimeter walls can add double-sided racks in the center of the floor plan as inventory expands, creating a layout that maximizes cubic storage within the existing building envelope.

Model Range for Different Pipe Lengths

Pipe length drives rack dimensions. A 6-meter pipe needs a rack with arms long enough to support the full length without excessive overhang. A 12-meter pipe needs a substantially larger structure. Herochu covers the most common industrial pipe lengths with four base models, though customization extends beyond what the table shows:

The layer counts shown are starting configurations. Each model supports additional layers by extending column height, subject to the total load on the floor anchors and slab. The 600-millimeter clear space between layers is a baseline — Herochu ships every rack with the arm spacing set to the customer’s specification, not to a factory default.

For warehouses that handle mixed lengths, rows can mix models. A 6-meter bay sits next to a 9-meter bay within the same row, sharing a common column where dimensions align. This mixed-length capability means a warehouse does not need separate storage zones for short pipes and long pipes — everything lives in the same aisle, organized by product type rather than product length.

Dual-Side Mechanical Loading

Every Herochu pipe cantilever rack includes dual-side mechanical assistance for material discharge. The manual crank mechanism operates from either face of the rack, enabling a bidirectional workflow that single-side-loading racks cannot support.

In a high-volume pipe warehouse, this dual-side capability translates into a flow-through layout. Inbound shipments arrive on one side of the rack row. Receiving operators load pipes into compartments using the crane for vertical lift and the crank for horizontal positioning. Outbound picking happens from the opposite side. Pickers access compartments without entering the receiving zone, and receiving operators load without navigating around pickers. The two workflows run concurrently rather than sequentially, which compresses the time between material receipt and customer shipment.

The manual crank itself uses a gear-reduction mechanism sized for the rated load. Turning the hand wheel at a comfortable pace moves a 3-ton or 5-ton load along the arm at a controlled speed — fast enough that loading a 12-meter compartment takes under a minute once the bundle is on the arm, slow enough that the operator maintains full control throughout. The crank assembly rides on sealed bearings and requires only periodic grease application as routine maintenance. There is no motor to burn out, no control panel to troubleshoot, no sensor to calibrate.

Q235B Steel Frame and Long-Term Durability

Pipe warehouses subject racking to conditions that accelerate deterioration if the steel is not properly specified and finished. Condensation forms on cold pipe surfaces and drips onto rack arms. Cutting fluid residue from freshly machined tube ends transfers to arm surfaces during loading. Outdoor or semi-enclosed storage bays bake in summer sun and freeze in winter, cycling the steel through thermal expansion and contraction daily.

Herochu fabricates the entire frame — columns, arms, crossbars, and base plates — from Q235B carbon structural steel. This grade provides a minimum yield strength of 235 MPa and maintains its mechanical properties through the temperature range that industrial warehouses experience. The steel arrives with mill test certificates that Herochu verifies against purchase specifications before releasing material to the fabrication line.

After fabrication, every component receives a powder-coated finish applied electrostatically and cured in an oven. The coating bonds to the steel surface at a molecular level, creating a uniform protective layer that resists chipping, scratching, and corrosion better than wet paint. For facilities in coastal or high-humidity environments, Herochu offers hot-dip galvanizing as an upgrade. The galvanized zinc layer provides sacrificial protection — if the surface gets scratched during loading, the surrounding zinc corrodes preferentially, leaving the underlying steel intact.

Maximizing Warehouse Cube Utilization

The economic argument for cantilever racking over floor stacking comes down to cubic utilization. A 12-meter pipe resting on the warehouse floor occupies roughly 1.2 square meters of floor space if stored in a single layer. Stack that pipe 5 high on a floor pile and the floor utilization improves, but the bottom pipe now carries the weight of four pipes above it, and retrieving the bottom pipe requires moving the top four.

A 5-tier Herochu cantilever rack stores the same five pipes in five independent compartments within roughly the same floor footprint, but with zero weight transfer between layers and full independent access to every pipe. The 6-tier HC-G9065 and HC-G12065 models push this ratio further, storing six layers in the space that a floor pile would occupy.

The real density gain multiplies when considering aisle width. Floor-stacked pipes require wide aisles for forklift maneuvering around irregular pile edges. Cantilever racks present a uniform face to the aisle, so aisle width can shrink to the forklift’s turning radius plus a safety margin. Narrower aisles mean more rack rows in the same building, which means more total storage capacity per square meter of warehouse floor.

Fast Installation and Reconfiguration

Herochu cantilever racks ship as a bolt-together kit. Columns, arms, base plates, crossbars, and fasteners arrive on a flatbed, organized by bay. Installation follows a straightforward sequence: anchor the base plates to the floor, bolt the columns to the base plates, attach the arms at the specified heights, and connect the crossbars between adjacent arms. A two-person crew with an impact wrench and a torque wrench can assemble a standard 6-meter bay in under four hours.

The absence of field welding carries several operational advantages. No hot-work permit means installation can proceed while the warehouse operates in adjacent areas — there is no requirement to clear the building or post a fire watch. The factory powder coating remains intact because nothing gets burned, ground, or scarred during assembly. If the rack needs reconfiguration later — arm spacing adjusted, layers added, bays relocated — the same bolt-together design makes the process equally straightforward. Unbolt, reposition, re-torque.

For warehouses planning phased rollouts, the modular design supports incremental deployment. Install one row this quarter. Add a second row next quarter as inventory grows. Extend existing rows as new product lines come online. Each phase uses identical components and the same installation procedure, so the learning curve from the first bay carries forward to every subsequent expansion.

Warehouse Safety and Operator Confidence

Floor-stacked pipe creates hazards that safety managers document in every incident report. Pipes roll when stepped on. Bundles shift when the bottom layer settles. Forklift operators navigate around irregular pile edges with limited visibility. A cantilever rack eliminates these hazards by design. Every pipe bundle sits in a defined compartment with arms that prevent rolling. Aisle faces are straight and predictable. Forklift approach paths are consistent from bay to bay.

The manual crank mechanism adds a layer of operator safety during loading. Rather than standing next to a swinging pipe bundle and guiding it by hand — a common but dangerous practice in un-racked pipe yards — the operator stands at the crank position, several feet from the load path. The crank controls the horizontal movement, so there is no reason for anyone to be in the bundle’s travel zone during loading or unloading.

Compartment labels — whether handwritten tags, barcode stickers, or RFID tags — give every SKU a permanent home. New operators learn the layout once and follow it every shift. There is no institutional knowledge about which corner of the warehouse holds a particular pipe grade or diameter, because the rack layout documents it. This transparency supports cross-training, shift handoffs, and temporary labor during peak periods.

Certification and Compliance

Herochu pipe cantilever racks carry CE marking and EU compliance documentation, confirming that the design meets structural safety and workplace health requirements for European markets. ISO 9001 certification covers the manufacturing quality system, from incoming material inspection through final dimensional verification before shipment.

Each rack ships with a certificate of conformance that links the serial-numbered columns to their material heat numbers. This traceability supports insurance audits, regulatory inspections, and internal quality management system requirements. For warehouses operating under ISO-certified management systems, the documentation package integrates directly into existing equipment procurement and safety verification workflows.

A Warehouse System That Adapts

The adjustable cantilever racking system from Herochu addresses the storage problem that pipe warehouses face every day: how to store long, heavy, varied products in a way that protects material quality, speeds up picking and put-away, and adapts as inventory changes over time. The modular Q235B steel frame adjusts arm spacing in minutes. The dual-side manual crank loading system supports flow-through warehouse layouts. The independent compartment design keeps products separated, labeled, and instantly accessible. For tube and pipe warehouses that need storage density without sacrificing flexibility, this system delivers a practical, durable answer.

Steel service centers and metal fabrication shops manage an inventory problem that standard pallet racking cannot solve. Steel bars arrive in lengths of 6 to 12 meters. Round pipes, square tubes, flat bars, and angle irons all demand dedicated storage that prevents bending, isolates grades, and lets operators retrieve the right material without reshuffling half the warehouse. Herochu addresses this with an industrial cantilever storage rack system built around a dual-beam crossbar frame — a structural approach that distributes heavy loads across multiple support points rather than concentrating stress at single arm connections.

Why Standard Racking Fails for Long Steel Products

Pallet racks work because pallets are uniform. A 48-by-40-inch pallet slides onto a pair of beams, the weight distributes evenly across two supports, and the system functions predictably for decades. Steel bars break that model. A 9-meter length of 50-millimeter diameter round bar weighs over 140 kilograms and spans far beyond any pallet rack beam pair. Support it at only two points and the unsupported center section sags under its own weight. Support it poorly and the bar rolls, slides, or drops when an operator attempts retrieval.

Cantilever racks resolve this by providing multiple support arms along the length of the material. Each arm carries a fraction of the total weight, keeping deflection within acceptable limits. But not all cantilever racks distribute load equally well. Herochu’s dual-beam crossbar design takes the concept further by connecting adjacent arms on the same tier with a horizontal structural tie. This transforms individual cantilever arms — each fighting gravity alone — into a unified load-sharing assembly.

Dual-Beam Crossbar: Engineering That Prevents Sag

A conventional cantilever arm bolts to the upright column at a single point. The arm functions as a true cantilever: fixed at one end, free at the other. Under a 3-ton load, the bending moment at the connection point is substantial. Over hundreds of loading cycles, microscopic yielding at the bolt hole can accumulate into visible arm droop. Operators compensate by shimming or over-tightening bolts — temporary fixes that mask a structural problem.

Herochu’s dual-beam crossbar ties the free ends of adjacent arms together with a horizontal beam. This connection changes the load path. Instead of each arm acting independently, the crossbar redistributes weight so that a heavy load on one arm receives partial support from its neighbors. The result is lower peak stress at any single connection point and more uniform deflection across the entire tier. For facilities storing dense bar stock — where a single compartment might hold several tons of solid round bars stacked three or four rows deep — this load-sharing behavior keeps the rack straight over years of heavy use.

Q235B Steel: The Right Grade for Static Load-Bearing

Structural steel selection matters for racking, not because the loads are dynamic in the aerospace sense, but because the rack sits under load continuously for years. Creep — the slow, permanent deformation of metal under sustained stress — becomes a design consideration when a 5-ton pipe bundle occupies the same compartment for six months at a time.

Q235B carbon structural steel offers a yield strength of 235 megapascals minimum, with an ultimate tensile strength in the range of 370 to 500 megapascals. These values place it in the sweet spot for static storage applications: strong enough to handle rated loads with generous safety margins, ductile enough to deform visibly before fracture, and weldable with standard procedures that do not require preheating or post-weld stress relief. Herochu fabricates columns, arms, and crossbars from Q235B and verifies material certificates for every heat of steel that enters the production line.

The frame geometry also contributes to load capacity. Columns use a closed box section rather than open C-channel, providing torsional rigidity that resists twisting when loads shift during crane operations. Base plates spread the column load across a wider area of the warehouse floor, reducing the point pressure that can crack floor slabs in older facilities.

Load Capacity and Safety Margins

Each Herochu compartment carries a rated load between 3,000 and 5,000 kilograms, depending on model and arm configuration. The rating is not a theoretical maximum — it represents the working load that the compartment handles daily without progressive deformation. Behind that rating sits a 150 percent overload test protocol. A 5-ton rated compartment undergoes static loading at 7.5 tons. The structure must hold that overload without permanent deflection exceeding 0.5 percent of the arm span. This margin accounts for several real-world scenarios: the momentary impact when a crane deposits a bundle, the uneven weight distribution when pipes shift slightly during placement, and occasional overloading when operators estimate bundle weight incorrectly.

For steel bar storage specifically, load distribution becomes more predictable than pipe storage. Solid bars sit flat on the cantilever arms with full surface contact. Round bars nest into each other but still transfer weight directly downward rather than creating point loads at pipe-to-pipe contact lines. Herochu designs arm surfaces with a slight inward tilt — typically 2 to 3 degrees — that naturally guides round stock toward the column rather than toward the open end of the arm. This geometry detail is subtle but consequential: it prevents the gradual outward roll that can occur when round bars rest on perfectly horizontal arms under warehouse vibration.

CE, EU, and ISO 9001 Certification

Industrial racking in regulated markets requires documentation that goes beyond a spec sheet. Herochu holds ISO 9001 certification for its quality management system, which governs everything from incoming material inspection to final dimensional checks before shipment. Each rack system ships with a certificate of conformance that ties the serial-numbered columns and arms to their specific heat of steel, providing full traceability if an auditor or insurer ever needs to verify material provenance.

CE marking confirms that the rack design meets the essential health and safety requirements of applicable European directives. For cantilever racking, this primarily involves structural integrity under load and the absence of sharp edges or pinch points that could injure operators during normal use. EU compliance extends this framework to member-state-level regulations, giving facility managers in European markets confidence that the rack meets local workplace safety standards without requiring additional engineering review.

Steel Bar and Pipe Applications

The same rack structure handles both bar and pipe storage because the cantilever arm concept is format-agnostic. A compartment that holds 3 tons of 100-millimeter round bars on Monday can hold 3 tons of 150-millimeter schedule-40 pipe on Tuesday — no reconfiguration required beyond possibly adjusting arm spacing if the product diameters differ significantly.

Steel service centers use Herochu cantilever racks to organize inventory by grade, diameter, and heat number. The independent compartment structure means that 304 stainless bars sit in labeled bays separate from 316 stainless, eliminating the grade-mix errors that cause costly customer rejections. Structural steel fabricators store angle irons, channels, and I-beams in compartments organized by section size, letting the cutting station pull the right stock without searching through mixed piles.

Pipe distributors benefit from the dual-side access configuration. One side of the rack faces the receiving dock, where inbound bundles load directly into compartments. The opposite side faces the shipping area, where pickers retrieve orders without crossing into receiving traffic. This flow-through layout cuts material handling time and reduces forklift congestion during peak operating hours.

Manual Crank Precision for Bar and Pipe Loading

Long steel products present a handling challenge that short pallets do not. A 12-meter bundle of pipe, suspended from a single crane hook, behaves like a pendulum. Even with tag lines, the bundle drifts during transport and requires several attempts to align with the target compartment. Each failed attempt burns crane time and risks impact damage to adjacent compartments.

Herochu integrates a manual crank mechanism into the loading path. The crane operator positions the bundle within the compartment bay — precision is helpful but not critical — and lowers it onto the crank-guided carriage. A ground-level operator then uses the hand crank to advance the bundle along the arm until it reaches its final position. The crank provides mechanical advantage that makes moving 5-ton loads across the arm surface a one-person task. It also constrains lateral movement, so the bundle cannot swing into neighboring compartments.

For bar stock specifically, the crank mechanism adds value when loading dense, heavy bundles. Solid bars stack more compactly than pipes, so a full compartment of round bar stock weighs near the maximum rated load. The crank’s gear reduction transforms this weight into manageable hand-wheel effort, eliminating the need for secondary handling equipment at the rack face.

Installation Without Field Welding

Herochu cantilever racks use a bolted assembly system that arrives at the job site ready to erect. Columns bolt to base plates with pre-drilled patterns. Arms bolt to columns. Crossbars bolt between arms. Every connection uses Grade 8.8 high-strength fasteners torqued to specification with a standard impact wrench. No welding happens on site, which eliminates several cost and schedule variables: no hot-work permits, no certified welder scheduling, no fire watch, no grinding or repainting of field welds.

The factory-applied powder coating stays intact through installation. Touch-up paint is unnecessary because nothing gets burned, ground, or scarred during assembly. A standard 6-meter bay can go from crate to fully operational in a morning for a two-person crew. Larger installations scale linearly — a 10-bay row of 12-meter HC-G12065 racks might take two days with the same crew size.

Long-Term Return on Investment

A well-built cantilever rack delivers value across multiple dimensions. Floor space utilization improves as pipes and bars move from horizontal stacking to vertical compartments. The same 100-square-meter floor area that stored 200 pipe bundles at ground level can store 1,000 bundles in a 5-tier rack system — a 5x increase in storage density that delays or eliminates the need for warehouse expansion.

Material damage drops because pipes no longer rest on each other. Scratches, dents, and bends from floor stacking disappear almost immediately after racks go into service. For service centers that sell on visual quality — where a scratched stainless pipe loses value — this preservation alone can justify the rack investment.

Retrieval time shrinks because operators go directly to labeled compartments rather than searching through ground-level piles. A job that previously took 10 minutes of forklift maneuvering becomes a 2-minute pick from a known location. Over thousands of picks per year, the cumulative labor savings add up.

Herochu’s industrial cantilever storage rack system gives steel service centers, pipe distributors, and fabrication shops a structural platform that matches their inventory reality: long, heavy, and varied. The dual-beam crossbar, Q235B steel frame, manual crank assist, and independent compartment design combine into a storage solution that stays straight under load, protects material quality, and speeds up every pick and put-away cycle.

Industrial facilities that store long steel pipes, aluminum profiles, and heavy tubing face a recurring problem: floor-level stacking chews up square footage, exposes inventory to bending damage, and slows retrieval to a crawl every time a forklift operator needs to dig through a pile. A cantilever rack engineered specifically for classified pipe storage solves all three problems at once. Herochu builds these systems with independent compartments, dual-side access, and mechanical crank assistance — turning chaotic pipe yards into organized, high-density storage bays.

Why Floor Stacking Costs More Than a Rack

When 6-meter or 12-meter steel pipes lie on the warehouse floor, each bundle competes for the same horizontal real estate. Workers spend minutes, not seconds, locating the right diameter or wall thickness. Pipe surfaces scratch against each other. The bottom layer absorbs the weight of everything stacked above, leading to ovality and micro-deformation that quality control flags later. Forklift maneuvering around sprawling material piles introduces safety hazards that no amount of caution tape can fully eliminate.

Herochu’s heavy-duty cantilever rack replaces this mess with vertical compartmentalization. Each tier acts as an independent storage bay. Pipes sit on dedicated arms with clear space between layers — typically 600 millimeters, adjustable to match the job at hand. The result is a system where every pipe bundle has a defined home, every forklift operator knows exactly where to go, and inventory counts stay accurate without constant manual recounting.

Independent Compartment Design and Dual-Side Access

What distinguishes Herochu’s approach from generic cantilever racking is the compartment philosophy. Most cantilever systems treat all arms on one side as a single continuous shelf. That works for uniform products but falls apart when a warehouse handles mixed diameters, mixed materials, and mixed lengths. A 2-inch schedule-40 carbon steel pipe does not belong in the same slot as a 6-inch stainless tube, yet that is exactly what continuous-arm racks force operators to do.

Herochu splits each tier into independent compartments on both sides of the upright column. A single rack structure can hold carbon steel pipes on the left compartments, stainless tubing on the right, and aluminum extrusions on a separate row entirely — all within the same footprint. This classification strategy cuts retrieval time because operators no longer sort through unrelated materials to reach the target bundle. Dual-side access also means two forklifts can load or unload simultaneously without traffic conflicts, a practical advantage that speeds up shift-change workflows in busy service centers.

Manual Crank Assistance for Space-Saving Loading

Loading a 3-ton bundle of 12-meter steel pipes onto an elevated cantilever arm demands precision. Cranes and overhead hoists provide the lifting muscle, but positioning the load over the correct compartment without scraping adjacent bays requires fine control. Herochu integrates a manual crank mechanism into the material discharge path. Rather than relying on crane operators to finesse long loads into tight spaces, the crank lets a ground-level worker guide the pipe bundle along the arm with controlled, incremental movement.

This mechanical-assist approach saves warehouse floor space because aisles can be narrower. Crane operators do not need wide approach angles or extra clearance to swing loads into position. The crank handles the final positioning step, absorbing the lateral drift that makes long-pipe loading unpredictable. It also reduces the risk of collision damage — pipes do not swing into neighboring compartments during loading or unloading because the crank constrains the movement path.

Load Capacity and Structural Integrity

Each Herochu compartment carries between 3 and 5 tons, depending on the model configuration. That capacity range covers the vast majority of industrial pipe storage applications — from bundled 6-meter structural tubing to dense stacks of solid bar stock. The frame that supports these loads starts with Q235B high-strength structural steel, chosen for its consistent yield characteristics and weldability. Herochu runs every design through finite element stress analysis to verify that load paths distribute evenly across the dual-beam crossbar assembly, eliminating the single-point stress concentrations that cause older cantilever designs to sag over time.

The dual-beam crossbar deserves specific attention. In a standard cantilever rack, each arm connects to the upright column at a single attachment point. Under heavy loading, that point becomes a pivot — repeated loading and unloading gradually deforms the bracket, and arm deflection increases year over year. Herochu’s dual-beam design adds a secondary horizontal tie between adjacent arms on the same tier. This tie transforms the individual cantilever arms into a collaborative load-sharing group. Deflection under full rated load stays within engineering tolerances, and the arms return to true position when unloaded. For warehouse managers who track rack integrity as part of their ISO audit checklists, that predictability matters.

Q235B Steel Frame and Anti-Corrosion Finish

Q235B steel provides a minimum yield strength of 235 megapascals — adequate for static storage loads with the safety margins that industrial racking standards require. Herochu applies a powder-coated finish over the entire frame after fabrication, not just on visible surfaces. This matters in pipe storage environments where condensation from temperature swings, cutting fluid residue on newly machined parts, and general warehouse humidity all contribute to corrosion. A rack that rusts at the bolt holes or weld seams becomes a liability within two to three years. Full-coverage powder coating extends service life significantly, particularly in coastal or high-humidity regions.

The steel columns and arms are also hot-dip galvanized as an option for facilities that store pipes outdoors or in semi-enclosed sheds. Galvanizing adds a sacrificial zinc layer that protects the underlying steel even if the surface gets scratched during loading operations — a realistic scenario when heavy pipe bundles slide across arm surfaces.

Herochu offers the heavy-duty pipe cantilever rack in four base configurations that scale with the most common pipe lengths:

The “S” designation on the HC-G6053S indicates a single-sided configuration for installations where the rack backs up against a wall. All other models default to double-sided storage, doubling the material capacity per bay. Clear space between layers starts at 600 millimeters and adjusts upward to accommodate oversized pipe diameters or bundled loads. Layer count is fully customizable — the five or six layers shown in the table represent common configurations, not hard limits. Facilities storing predominantly smaller-diameter tubing can request additional layers within the same column height to maximize vertical density.

Dual-side mechanical assistance comes standard across the entire range. The manual crank mechanism operates identically whether the operator is loading 3-ton 6-meter bundles or 5-ton 12-meter loads — the mechanical advantage scales with the load through the gear reduction built into the crank assembly.

Global Certifications and Quality Standards

Herochu manufactures these rack systems under ISO 9001 quality management protocols. Every load-bearing weld undergoes visual and dimensional inspection before the frame moves to finishing. The completed racks carry CE and EU compliance markings, confirming that structural design, material traceability, and safety documentation meet the requirements for deployment in European and international industrial facilities.

Load testing follows a 150 percent overload protocol. A compartment rated for 5 tons undergoes static testing at 7.5 tons to confirm that the structure holds without permanent deformation. This margin accounts for dynamic loads that occur during loading — when a crane deposits a pipe bundle, the momentary force exceeds the static weight — and provides an engineering buffer for facilities that occasionally push their storage density beyond planned limits.

Installation and Operational Benefits

Herochu cantilever racks ship with a bolt-together design that eliminates on-site welding. Floor anchors secure the base plates to the warehouse slab, and the columns bolt to the base plates with pre-drilled hole patterns that enforce correct alignment. A crew of two can assemble a standard 6-meter bay in under four hours using basic hand tools. The absence of field welding means no hot-work permits, no fire watch requirements, and no grinding or repainting after installation — the factory-applied powder coating stays intact.

Once installed, the operational benefits compound. Pipe bundles move from floor stacks into labeled compartments. Inventory clerks can walk an aisle and visually confirm stock levels without climbing over piles. Forklift operators retrieve full bundles in a single lift rather than picking individual pipes out of a mixed stack. New hires learn the rack layout once and apply it every shift — there is no tribal knowledge about which corner of the warehouse holds the 4-inch schedule-80 pipe because every compartment has a defined assignment.

For facilities expanding their pipe inventory or reorganizing their floor plan, the bolt-together design allows partial disassembly and reconfiguration. Add more bays by extending the row. Adjust arm spacing by unbolting and repositioning the arms on the column. The system adapts as storage needs change, which protects the initial capital investment over a service life measured in decades rather than years.

A Smarter Approach to Pipe Storage

Industrial pipe storage does not need to mean sprawling floor piles, damaged inventory, and frustrated operators. Herochu’s classified compartment cantilever rack brings order to pipe yards and service centers through independent tier storage, dual-side mechanical loading, and structural engineering that holds 3 to 5 tons per compartment without deflection. The Q235B steel frame, powder-coated finish, and bolt-together assembly make it a practical, long-term investment for any facility that handles 6-meter, 9-meter, or 12-meter pipes, tubes, and profiles.

Industrial fabrication shops move tons of structural steel through their bays every day, yet many still store long materials on floor-level dunnage or in fixed-arm racks that demand forklift-width aisles between every row. The mismatch between material value and storage infrastructure costs money in three forms: damaged stock from compression and weather exposure, wasted labor hours spent searching and repositioning, and lost floor area that could house additional production equipment instead of idle inventory.

Herochu heavy-duty cantilever racking systems are purpose-built to close this gap. Designed around Q235B structural steel frames with independently extendable arms, these racks store steel tubes, solid bars, and structural profiles in classified compartments that an operator can access one tier at a time — without maneuvering a forklift into a narrow aisle.

Storage Density That Changes Facility Layout Math

The economic argument for high-density cantilever storage begins with real estate cost. In most industrial parks, floor space costs between four and eight dollars per square foot per year when lease, utilities, and maintenance are bundled. A single fixed-aisle cantilever row covering 200 square meters of floor might store 800 linear meters of 6-meter pipe. A Herochu telescopic cantilever row occupying the same footprint stores 1,600 to 2,400 linear meters because the space that was reserved for forklift turning radius becomes additional rack bays.

This density gain often eliminates the need for off-site overflow storage — a recurring expense for service centers that rent yard space for slow-moving inventory. Bringing that material back under the main roof reduces double-handling, protects it from rain and UV exposure, and makes it available for same-day picking when a rush order lands.

Structural Engineering for Asymmetric Loads

A cantilever arm holding 5,000 kg of nested steel tube exerts enormous bending moment at the column connection point. Herochu addresses this with a dual-beam crossbar design rather than a single cantilever beam. Two parallel longitudinal members — one on each side of the column — create a box-section moment connection that resists torsion far better than a single-beam mount.

This matters in practice because steel bundles rarely distribute weight evenly. A bundle of mixed-diameter seamless tubes may concentrate 70 percent of its mass in the front third of the arm. On a single-beam cantilever, this forward weight bias twists the arm and eventually deforms the connection bracket. The dual-beam configuration on Herochu racks creates a wider stance at the pivot point, transferring torque into the column through two separated load paths. Independent engineering analysis typically shows deflection under maximum load staying within 2 mm at the arm tip — values that preserve arm alignment over thousands of extension and retraction cycles.

Material Protection Through Compartmentalized Storage

Steel distributors lose measurable revenue to material degradation that happens during storage rather than during processing. Mill scale chips off when tubes roll against each other. Galvanized coating scratches when profiles shift under stack weight. Threaded pipe ends deform when heavier bundles rest on top of them. These damages are cumulative, silent, and almost entirely avoidable through proper compartmentalization.

Each Herochu rack tier functions as an isolated storage cell. Pipes in compartment A never bear the weight of pipes in compartment B. Profiles in tier three do not press down on tubes in tier two. Because every compartment extends independently, the operator never needs to lift bundles off other bundles — the target material is always the only material exposed at the point of access. Surface quality stays consistent from receiving to issue, cutting downstream reject rates at fabrication and finishing stations.

Classified Storage for Inventory Control

The organizational advantage of independent compartments extends beyond physical protection. When every tier holds a single material grade, diameter, and length combination, inventory counting shifts from estimation to exact count. A warehouse supervisor walking the rack row can verify stock levels in under a minute per bay because the contents of each cell are visible from either face and never mixed.

This granularity also enables practical first-in-first-out rotation — a requirement for carbon steel pipe susceptible to atmospheric corrosion, and for alloy grades where heat number traceability matters for end-user certification. New receipts load from the rear face while production pulls from the front face, cycling inventory without manual restacking.

Manual and Electric Operation Across Fleet Sizes

Manual crank racks serve operations where a single bay handles a dozen picks per shift. The worm-gear hand crank provides mechanical advantage sufficient for one operator to extend a fully loaded compartment without assistance. The motion is smooth and controlled — no sudden acceleration that could shift a loosely banded bundle — and the crank handle returns to a neutral locked position when released.

Electric drive versions scale to high-throughput environments where dozens of picks per hour cross multiple bays. Each bay carries its own push-button control station with individual extend and retract buttons per tier. The interlock system prevents a second tier from extending while one is already deployed, eliminating the combined cantilever moment that could destabilize the column. For facilities with a warehouse management system in place, Herochu provides integration protocols that let the WMS send pick commands directly to the correct bay and tier — the rack is already extended and waiting when the operator arrives with the crane or forklift.

Specification Range

The standard Herochu cantilever rack product line covers four frame models. HC-G6053 and HC-G6053S handle 6,000 mm material lengths with 5 configurable tiers rated at 3,000 kg per compartment. HC-G9065 accommodates 9,000 mm stock across 6 tiers at 5,000 kg per level. HC-G12065 supports 12,000 mm lengths with 6 tiers at 5,000 kg per compartment. All models feature dual-side mechanical-assisted discharge for flexible loading and retrieval workflows.

Clear vertical spacing between arms is specified at order to match the customer’s maximum bundle diameter, typically 500 mm to 800 mm. Arm length and compartment width follow the same custom-specification approach — the rack is built around the material, not the other way around.

Long-Term Value for Steel Handlers

A properly specified cantilever rack from Herochu operates for 15 to 20 years in a typical fabrication environment with basic periodic inspection of the drive mechanism and arm alignment checks. The Q235B frame carries corrosion-resistant factory coating rated for indoor industrial exposure. Electrical components in motorized models use IP54-rated enclosures that stand up to the ambient dust and occasional coolant mist common in metalworking facilities.

For businesses evaluating whether the capital cost of a heavy-duty telescopic system pencils out against continued use of floor stacking or fixed racking, the variables that dominate the equation are labor hours per pick (typically cut by 60 to 70 percent), floor area reclaimed (typically 50 to 65 percent), and material damage reduction (variable by operation but consistently positive). When all three factors combine across a full year of operation, payback periods under 18 months are common for facilities handling more than 500 metric tons of long stock annually.

When warehouse operations involve solid steel bars, concrete pipes, or heavy machinery shafts, standard cantilever racks often fail. The arms bend, the adjustments are coarse, and the safety factors are too low. Herochu developed a line of heavy‑duty cantilever racks with adjustable arms specifically for loads ranging from 1 to 10 tons per layer, with a single arm capable of holding 6 tons. This article explains the engineering behind the adjustability, the telescopic option, and why these racks outperform fixed‑arm designs in real industrial environments.

The Core Problem with Fixed Cantilever Arms

Many warehouses still use welded cantilever racks where the arm positions are permanent. When inventory changes—e.g., switching from 8‑meter pipes to 4‑meter tubes—the fixed arm spacing becomes inefficient. Either the gap is too large, wasting vertical space, or too small, blocking crane access. Heavy‑duty cantilever racks with adjustable arms solve this by allowing the end user to reposition arms along the upright column without tools. Herochu uses a ladder‑style column with punched oval holes on 75 mm centers. Each arm inserts via a heavy‑gauge steel hook plate that engages three holes simultaneously, distributing the shear load evenly.

Adjustability Meets Heavy Loads

Most adjustable arms in the market lose load capacity because the connection is a single pin or a shallow hook. Herochu’s design features a 12 mm thick backplate with four hardened steel pins. When the arm is lowered into place, the pins lock into the column holes, and a spring‑loaded safety clip prevents accidental dislodging during crane loading. This connection has been cycle‑tested for 50,000 load‑unload cycles at 5 tons without measurable wear. The arm itself is fabricated from a continuous C‑channel of 8 mm high‑strength steel, reinforced with a 6 mm web stiffener along the first 300 mm from the column—the highest stress region.

Telescopic Heavy‑Duty Arms for Maximum Flexibility

Beyond vertical adjustability, Herochu offers a telescopic version. The main arm extends from 800 mm to 1,600 mm (100% extension rate). This is critical for warehouses storing both short billets (2‑3 m) and full‑length pipes (6‑12 m). With a telescopic arm, the operator retracts the arm when storing short items to keep the aisle clear, then extends it for longer items without moving the entire rack. The telescopic mechanism uses roller bearings and a double‑acting hydraulic damper to prevent sudden ejection. Each telescopic heavy‑duty cantilever rack with adjustable arms can handle 3 tons in the fully extended position—a remarkable figure for a moving component.

Application in Factory Pipe Storage

In a typical pipe warehouse, materials come in varying diameters and lengths. Floor stacking forces operators to maintain multiple piles, each requiring its own forklift aisle. Herochu’s heavy‑duty cantilever racks with adjustable arms consolidate these piles into a single vertical footprint. For example, a warehouse storing 6‑meter Schedule 40 steel pipes (approx. 800 kg per length) can store 12 pipes per arm (three arms per column = 36 pipes per upright). By adjusting arm spacing from 600 mm to 900 mm as the pipe diameter changes, the warehouse achieves near‑100% vertical utilization.

Safety Features Integrated into Heavy‑Duty Design

The same arms that hold 6 tons must also prevent round materials from rolling off. Herochu equips each arm tip with an integrated anti‑slip stopper—a welded steel plate rising 80 mm above the arm surface. For extra safety, rubber‑lined magnetic stoppers are available for storing polished or chrome‑plated pipes. Additionally, the heavy‑duty cantilever racks with adjustable arms include a column base with pre‑drilled holes for floor anchoring. Overturning is prevented even when an unbalanced load is placed on only one side of a double‑sided rack.

Single‑Sided vs. Double‑Sided Configuration

Herochu offers both configurations. Single‑sided racks are ideal for wall‑adjacent storage or for creating a “storage spine” along a production line. Double‑sided racks (back‑to‑back) double the storage density and are typically placed in the center of large pipe warehouses. Both types use the same adjustable arms and column profiles. The double‑sided version includes horizontal tie bars every 1.2 meters to ensure both sides share lateral loads. For warehouses with ceiling height limitations, Herochu can supply floor‑mounted only two‑level racks with extended arm lengths up to 1,800 mm.

Economic Impact: Reducing Labor and Space

Data from Herochu’s installation at a prefabricated construction material supplier shows a 50% reduction in operation time compared to floor stacking. Before installation, retrieving a specific 9‑meter steel beam took two forklift operators and 20 minutes of shuffling other beams. After implementing heavy‑duty cantilever racks with adjustable arms, one operator using an overhead crane retrieved the same beam in 90 seconds. The warehouse reclaimed 200 m² of floor space, which was converted into an additional assembly station. The system paid for itself in less than nine months through labor savings alone.

Customization and Certification

Herochu’s factory supports full customization: arm length (300 mm–1,800 mm), number of arms per column (2 to 6), and total height (up to 8 meters for single‑sided, 6 meters for double‑sided). All heavy‑duty cantilever racks with adjustable arms are CE certified and manufactured under ISO 9001:2025 standards. The company’s in‑house engineering team provides free layout design using load‑simulation software. For international buyers, Herochu ships knocked‑down (KD) with assembly drawings and all bolts included.

In conclusion, heavy‑duty cantilever racks with adjustable arms from Herochu offer an unbeatable combination of strength, adjustability, and safety. They transform chaotic pipe storage into an organized, space‑saving system that cuts retrieval time by over 80%.

In the world of industrial storage, few applications are as demanding as long, heavy pipes and tubes. These products must be stored without bending, accessed without damage, and organized without chaos. Herochu has risen to this challenge with a dedicated line of Heavy-Duty Telescopic Storage Racks for Pipes, Tubes, and Long Products. Engineered specifically for loads up to 5 tonnes per layer and total rack loads exceeding 40 tonnes, these telescopic systems combine brute strength with precision engineering. They are not merely racks; they are material handling solutions that integrate seamlessly into high-throughput environments like steel service centers, oilfield supply yards, and automotive tubing warehouses.

The term “telescopic” in Herochu’s context refers to the full-extension drawer mechanism. Each storage level consists of a moving carriage that slides out from the fixed frame, supported by robust linear guides. The carriage extends completely – typically 90% to 100% of its length – so that the entire pipe or tube is exposed. This is a critical feature for heavy-duty applications. If a rack only extends partially, you still have to reach into the rack to grab the back end of a 12-meter pipe, defeating the purpose of accessibility. Herochu’s telescopic design ensures that when the drawer is fully opened, the furthest point of the stored pipe is within easy reach of an overhead crane or monorail hoist.

Herochu offers four standard heavy-duty models, each built around a specific length and capacity. The HC-G6053D provides 3 tonnes per layer at 6 meters length, with bilateral assistance. The HC-G9055S delivers 5 tonnes at 9 meters but only unilateral assistance – meaning drawers extend to one side only. The HC-G9055D is the bilateral version of the same 5-tonne, 9-meter platform. The HC-G12055D stretches to 12 meters while maintaining 5 tonnes per layer and bilateral extension. All models feature “4+1” layer configuration: four primary storage drawers plus one additional layer designated for bilateral or unilateral assistance, depending on the model. This “+1” layer is often used for storing short offcuts, tools, or accessories, keeping everything organized in one rack bay.

What makes Herochu’s Heavy-Duty Telescopic Storage Racks for Pipes, Tubes, and Long Products stand out is the attention to dynamic loading. Many storage racks are rated for static loads – the weight they can hold when stationary. But telescopic racks experience dynamic loads during extension: the drawer and its contents shift weight forward, applying torque to the slides and frame. Herochu engineers rate their racks for dynamic operation, meaning the 5-tonne capacity applies even when the drawer is fully extended. This is achieved through dual linear bearing blocks per rail, oversized wheel diameters, and a low-friction composite slide surface. Accelerated life testing exceeds 50,000 extension cycles without degradation.

Both manual and electric actuation options are available. The manual version uses a geared crank or pull handle connected to a chain-and-sprocket system. A torque multiplier reduces the effort required; one person can extend a 5-tonne loaded drawer with about 25 kg of pulling force. Positive stops at full extension and full retraction prevent over-travel. The electric version adds a PLC-controlled motor drive with encoder feedback for precise positioning. The operator simply presses a button, and the drawer glides out smoothly, with adjustable speed settings from 2 to 10 meters per minute. Safety features include automatic braking on power loss, obstruction detection (reversing direction if an object is encountered), and remote emergency stop.

Certification is non-negotiable for heavy-duty industrial equipment. Herochu’s telescopic storage racks are fully CE marked, meeting the Essential Health and Safety Requirements of the EU Machinery Directive. They also carry UE certification for the Ukrainian market, which aligns with technical regulations based on European standards. Additionally, ISO 9001:2015 certification covers Herochu’s entire design, manufacturing, and testing process. For customers requiring third-party inspections, Herochu can arrange witnessed load tests at the factory or on-site, with certified load cells and deflection measurement equipment.

The practical operation of these racks transforms pipe and tube handling. Consider a typical scenario: a warehouse receives a shipment of 9-meter steel tubes in various diameters. Without telescopic racks, workers would lay them on the floor or on static cantilever arms. To retrieve a specific tube from the middle of a stack, a forklift operator must lift the entire bundle, dig out the target tube, and restack the rest – a process that takes 10 minutes and risks damage. With Herochu’s HC-G9055D, each diameter is assigned to its own drawer. The operator pulls out the drawer, uses an overhead crane to lift the exact tube needed, and closes the drawer. Total time: 90 seconds. Damage: zero. Labor: one person.

Space savings are equally dramatic. Traditional pipe storage often requires aisles wide enough for a forklift to enter and maneuver – typically 4 meters or more. Herochu’s telescopic design reduces aisle width to 1.8 meters for bilateral racks (since drawers extend to both sides, the aisle serves both racks) or 1.5 meters for unilateral racks against a wall. In a 50-meter-long warehouse, switching from static cantilever to Herochu telescopic racks can free up over 100 square meters of floor space per row, which can then be used for additional racks or processing equipment.

Durability is built into every component. The steel used is S355JR grade (equivalent to ASTM A572 Grade 50), with a minimum yield strength of 355 MPa. All welded joints are continuously fillet-welded and inspected via magnetic particle testing. The finish is a two-component epoxy polyester powder coating, applied after shot blasting to Sa 2.5 cleanliness, providing corrosion resistance for indoor or covered outdoor use. Roller bearings are sealed against dust and require greasing only once every six months under normal operation.

Customization extends beyond the standard HC series. Herochu frequently produces heavy-duty telescopic storage racks for pipes and tubes with non-standard lengths (up to 15 meters), higher capacities (6 to 10 tonnes per layer), additional layers (up to 6), and specialized arm profiles for square tubes, channel sections, or I-beams. For operations that handle both full-length pipes and short remnants, Herochu offers dual-depth drawers: the lower drawer has reduced height for short pieces, while the upper drawers accommodate full lengths. Every custom order is modeled in 3D CAD, stress-analyzed using FEA, and prototype-tested before production.

In summary, Herochu’s Heavy-Duty Telescopic Storage Racks for Pipes, Tubes, and Long Products represent the gold standard for demanding industrial storage. With 5-tonne per layer capacity, lengths from 6 to 12 meters as standard (and custom beyond), both manual and electric operation, and full CE/UE/ISO 9001 certification, these racks deliver unmatched performance. Whether you are storing oilfield casing pipes, hydraulic tubing, structural steel, or aluminum extrusions, Herochu has a telescopic solution that will improve your safety, efficiency, and bottom line.

Warehouse managers overseeing long material storage face a persistent challenge: how to organize steel pipes, lumber, and structural components without sacrificing floor space or worker safety. Standard pallet racks fail when material lengths exceed eight feet, and floor stacking creates accessibility nightmares. The solution lies in a specialized system that combines vertical expansion with robust load-bearing engineering. Herochu presents its Heavy Duty Stackable Powder Coated Cantilever Rack, a modular storage architecture designed to transform sprawling laydown yards into organized, high-density storage environments.

Stackable Configuration for Vertical Warehouse Optimization

Traditional cantilever racks occupy a fixed footprint with limited height. Herochu’s stackable design breaks this constraint through a column coupling system that allows multiple rack units to mount directly atop one another. Each stackable cantilever rack section interlocks using precision-machined alignment pins and grade-8 bolted connections, creating a continuous column that transfers vertical loads directly to the floor without intermediate deflection. Facilities with overhead clearance of twenty feet or more can install two or three stacked tiers, effectively multiplying storage density without expanding building footprint.

The stackable configuration proves particularly valuable in metal service centers handling laser cutting sheets and tube stock. A single Herochu stackable powder coated cantilever rack installation measuring forty feet in length accommodates the same material volume as one hundred fifty feet of floor staging. This density improvement translates directly to reduced square footage costs, lower lighting and climate control expenses, and shorter travel paths for forklift operators.

Powder Coated Finish for Aggressive Industrial Environments

Corrosion protection separates temporary storage solutions from permanent infrastructure. Herochu applies a thermosetting polyester powder coating to every exposed steel surface of the cantilever rack system. The coating process begins with abrasive blasting to SA 2.5 cleanliness standards, removing mill scale and surface contaminants. An electrostatic spray gun then applies charged powder particles that bond to the grounded steel substrate. Final curing occurs in a gas-fired oven at 400 degrees Fahrenheit, cross-linking the polymer into a continuous film that resists chipping, scratching, and chemical attack.

This powder coated finish outperforms liquid paint systems in three critical areas. First, edge coverage remains uniform because electrostatic attraction pulls powder into corners and weldments where liquid paints thin out. Second, impact resistance exceeds 80 inch-pounds reverse impact, meaning dropped tools or bumped forklift masts will not expose bare steel. Third, salt spray resistance in ASTM B117 testing reaches 1,000 hours without undercutting, confirming suitability for coastal warehouses or facilities processing pickled and oiled materials.

Structural Engineering for Heavy Duty Load Application

The term “heavy duty” carries specific engineering meaning in cantilever rack design. Herochu defines heavy duty as per-arm capacities from one to ten tons, with column sections sized accordingly. The stackable powder coated cantilever rack uses either C-channel or I-beam column profiles rolled from HRB400 or Q355B steel. Column wall thickness ranges from 4mm to 8mm depending on height and load requirements, with finite element analysis confirming stress distribution across all weldments.

Arm attachments employ a four-bolt pattern through the column flange, unlike cheap wedge-fit designs that loosen under vibration. Each bolt receives torque verification during assembly, and lock washers prevent back-off from cyclic loading. The arm profile itself features a tapered I-beam shape, thicker at the column connection and reducing toward the tip where bending moments are lower. This variable cross-section saves weight while maintaining full capacity at the critical column interface.

Practical Application: Laser Cutting Sheet and Tube Storage

Laser cutting operations generate material in two forms: flat sheets and structural tubes. The Herochu stackable powder coated cantilever rack handles both within a unified system. Sheets load from the front using forklift-extended forks or vacuum lifters, sliding onto powder coated support arms with low-friction contact. Tubes and pipes load from the side, cradled between opposing arms that prevent rolling. For mixed storage, operators install shorter arms on upper tiers for remnant drops and longer arms on lower tiers for mill-length bundles.

Forklift loading receives specific design attention. Arm spacing accommodates standard fork widths of 41 inches, and the absence of upright cross-members eliminates the “post strike” damage common in selective rack systems. Herochu includes optional floor-mounted guide rails that center forklift approach angles, reducing driver training requirements and preventing accidental column impacts.

Long-Term Durability and Maintenance Considerations

A heavy duty stackable powder coated cantilever rack represents a decade-scale investment. Herochu supports this lifecycle with replaceable arm sleeves, bolt-in column stiffeners, and touch-up powder coating kits. Annual inspection protocols focus on bolt torque, arm deflection under load, and coating integrity at wear points. Should damage occur from extreme overload or forklift collision, individual arms or column sections unbolt and replace without disturbing the entire structure.

Temperature performance ranges from -30°C to 80°C continuous operation, with powder coating maintaining flexibility at low temperatures to prevent cracking. Outdoor installations benefit from UV-stable pigmentation that resists fading and chalking after years of sunlight exposure. For cold storage applications handling frozen pipe or lumber, the powder coated finish prevents moisture adhesion that accelerates rust on uncoated alternatives.

Conclusion

Herochu engineered the Heavy Duty Stackable Powder Coated Cantilever Rack to solve the specific pain points of long material storage: low density, corrosion vulnerability, and loading difficulty. The stackable design multiplies vertical space utilization, the powder coated finish preserves structural integrity in aggressive environments, and heavy duty construction ensures safe support for multi-ton loads. For warehouse managers ready to move beyond floor piles and undersized racks, this system delivers measurable operational improvement from day one.

The Challenge of Storing Long Goods

Engineered for Extreme Capacity and Durability

Customization: Tailoring the Rack to Your Inventory

• Adjustable Arm Lengths: Arms can be configured between 550mm and 800mm (or customized further) to perfectly match the depth of your goods, preventing overhang and maximizing aisle space.
• Vertical Flexibility: The height of the cantilever arms is fully adjustable along the column. This allows you to adapt the rack instantly if your inventory profile changes, accommodating everything from short lumber to tall piping.
• Single vs. Double Sided: Depending on your warehouse layout, you can opt for single-sided units against a wall or double-sided units in the center of the floor to create a high-density storage block.
