The Importance of CE Certification

Load Capacity Spectrum: 500kg to 5000kg

• Light to Medium Duty (500kg – 1000kg/layer): Ideal for storing thinner gauge metals, plastics, or wood veneers. These units are lighter and easier to maneuver but still maintain the structural integrity required for industrial use.
• Heavy Duty (3000kg – 5000kg/layer): Designed for heavy steel plates and dense materials. These units undergo rigorous stress testing to ensure that the drawer slides and frame welds can handle the extreme weight without deformation.

Integrated Safety Features

• Accidental Pull-Out Prevention: The integrated safety lock system is a critical component. In a busy warehouse, a forklift might brush against a rack. Without a locking mechanism, a fully loaded drawer could slide out, causing severe injury or damage. The Herochu locks prevent this, keeping the drawers securely in place until intentionally released by an operator.
• Elimination of Climbing and Reaching: Traditional storage often forces workers to climb on racks or reach high to retrieve sheets. This is a leading cause of warehouse injuries. The drawer design brings the material to the worker at a safe, ergonomic height. The drawers extend fully, allowing the worker to access the entire sheet without leaning over the edge.
• Material Containment: Loose sheets stacked on a floor are a tripping hazard and can topple over (the “domino effect”). The enclosed drawer design of the Herochu rack keeps materials contained and stable. This is particularly important for cut-offs and remnant pieces, which are often irregular and prone to falling over in a pile.

Protecting the Inventory

Compliance with International Shipping Standards

Conclusion

In industrial fabrication shops, lumber yards and plastic distribution centers, the constant challenge revolves around one persistent problem: how to store large-format sheet goods safely, accessibly and without consuming excessive floor space. Plywood panels, aluminum sheets, acrylics and composite plastics arrive in dimensions that defy standard shelving. Stacking them flat on the floor breeds damage, warping and safety hazards. Leaning them against walls creates trip risks and makes retrieval a two-person job. Herochu addresses all these pain points with a purpose-built material and panel storage rack engineered specifically for plywood, aluminum and plastics. This system brings order to chaos and turns dead floor space into a high-density vertical storage asset.

The Herochu material and panel storage rack starts with a fundamental design principle: every square foot of your facility costs money, so storage must exploit height rather than sprawling across the ground. The rack uses a vertical drawer architecture that compresses the storage footprint by up to 60 percent compared to traditional flat-stacking methods or cantilever aisles. Within the same bay that once held a single pile of plywood, a Herochu rack now stores multiple sorted compartments, each holding a different material type, thickness or grade. Warehouse managers consistently report reclaiming aisles for forklift traffic, staging areas for assembly and valuable workspace adjacent to CNC routers and saws.

Construction begins with heavy-gauge structural steel welded directly to the frame at every shelf anchor point. Rather than relying on bolted connections that can loosen under repetitive loading and unloading cycles, Herochu employs full-perimeter welding on all load-bearing joints. This technique distributes stress evenly and prevents the slow racking deformation that plagues lighter storage units. Each shelf and cassette assembly obtains a 3,000-pound uniform distributed load rating, meaning that even full drawers of ¾-inch plywood or stacked 0.125-inch aluminum sheets remain perfectly stable with the drawer in the fully extended position. The powder-coat finish applied in a multi-stage pretreatment process resists scratching, chemical exposure and the abrasive dust common in wood and metal shops.

Sizing accommodates the industry’s most common panel formats with ease. The rack cavity accepts materials up to 60 inches wide by 120 inches long, which handles standard 5-foot by 10-foot sheets without overhang or edge damage. Overall external dimensions measure 141-1/16 inches in width, 73-1/2 inches in depth and 73-1/4 inches in height for the base single unit. This footprint integrates smoothly into existing workflows because it aligns with standard forklift turning radii and does not protrude into designated egress paths. When material inventories expand, the Herochu rack grows vertically through a stackable architecture. One 6-foot unit can have another placed directly on top, achieving stack heights up to 12 feet while maintaining rock-solid alignment through engineered interlocking mast channels and base plate connections.

Material protection enters a new category with the integrated drawer design. Each cassette separates panels by type, thickness and alloy, so a fabricator never again needs to move four sheets of aluminum to reach the single sheet of polyethylene buried beneath. Drawers operate on heavy-duty roller bearing slides that achieve 100 percent extension, presenting the entire sheet face to the operator without any portion remaining inside the frame shadow. Retrieving materials no longer requires reaching, climbing or employing a second person to steady the load. The full-extension capability also means overhead crane access or vacuum lifters can engage the sheet directly from the drawer, streamlining loading onto cutting tables.

Safety systems on a Herochu material and panel storage rack are not an afterthought. Every individual drawer incorporates a lock-in, lock-out mechanism that physically prevents accidental rollout. In a busy shop environment where forklifts pass within inches of storage racks, an unintentionally extended drawer poses a severe impact and crush hazard. The Herochu lock engages automatically when the drawer reaches the closed position and requires a deliberate release action before extension is possible. During loading operations, the lock-out function secures the drawer in the fully open state, so it cannot creep backward while personnel position heavy sheets onto the cassette bed. These mechanical interlocks do not depend on electrical power or operator memory, delivering passive safety that works shift after shift.

Access is further enhanced by rear loading capability built standard into every model. Operators can load sheets from either the front or rear face of the rack, a feature that transforms material flow in linear production lines. Raw material arrives at the back of the rack from receiving, while the front faces the fabrication cell. When a CNC router consumes a sheet, the next panel moves forward without cross-traffic or double handling. This linear material management eliminates the wasted motion that accumulates significant labor cost over months of operation.

Forklift compatibility receives deliberate engineering attention. The bottom frame provides generous clearance with reinforced fork pockets sized for standard Class II and Class III forklift tines. Should a facility need to relocate a fully loaded rack, the entire assembly can be lifted and transported without unloading the drawers, provided the total gross weight stays within the lift truck’s rating. This feature saves hours of labor during shop reorganizations or when responding to changing production demands. For operations that ship pre-cut panels to job sites, a loaded rack can even serve as a mobile material cart moved to a staging area near the loading dock.

The rack’s classification capability drives efficiency metrics that warehouse managers track obsessively. By assigning dedicated drawers to specific material categories — ¼-inch Baltic birch plywood in drawer one, 0.080-inch aluminum tread plate in drawer two, ½-inch white HDPE sheet in drawer three — retrieval time drops to a fraction of previous durations. Workers no longer sort through mixed stacks, read faded marker labels or guess at thickness with calipers. The organized compartmentalization also slashes material handling errors. The wrong sheet thickness cut on a production run generates scrap, rework and schedule delays; the Herochu organized storage paradigm prevents these errors at their source.

Inventory visibility improves in lockstep with organization. Supervisors can open sequential drawers and visually scan stock levels in seconds rather than piecing together information from scattered stacks and siloed areas. Purchasing decisions become data-driven based on rapid physical inventory checks. For shops operating under lean manufacturing principles, this immediate visibility supports pull-based replenishment and prevents both stockouts and over-ordering of expensive sheet materials like cast acrylics or PVC foam board.

The roller bearing drawer slides merit special mention for their contribution to longevity and ease of use. Unlike plain-bearing slides that develop increasing friction as lubrication degrades or dust infiltrates, sealed roller bearings maintain consistent low-effort operation across years of daily cycling. Each bearing assembly incorporates hardened races and precision-ground rollers that distribute the drawer load across multiple contact points, preventing brinelling and flat-spotting even under sustained full-capacity loads. Drawer motion remains smooth and controllable from closed to fully extended, which is critical when maneuvering heavy and expensive sheet stock.

Vertical storage density shifts the economic equation for warehouse space. A single Herochu rack configured with 13 drawers stores the equivalent of 13 individual ground-level stacks, yet occupies only the footprint of one. For businesses leasing industrial space in high-cost markets, this compression directly reduces the dollars spent per stored sheet. The stackable design compounds the benefit: a two-high stack of 13-drawer racks stores 26 discrete material categories within the original footprint, without requiring a building expansion or off-site storage rental. The savings in lease cost, material handling equipment and labor combine to generate a compelling return on the rack investment, often measured in months rather than years.

Topology within the rack structure also prevents the sagging damage common to unsupported sheet goods. Plywood and plastic panels stored flat on the floor over time develop a permanent bow from their own weight unless supported by continuous dunnage. The Herochu drawer bed provides full-area support with a rigid steel platform, eliminating the conditions that cause warping. Flat material arriving from the supplier stays flat while in storage, which feeds flatter parts into processing machinery and reduces rejects caused by material deformation.

Noise and housekeeping receive collateral benefits. Sheet goods stored vertically in closed drawers do not vibrate against one another when forklifts roll past, reducing the overall noise level in the shop. The enclosed drawer fronts also prevent sawdust, grinding grit and overspray from settling onto stored material surfaces, which is particularly important for pre-finished plywood, anodized aluminum sheets and optically clear plastics. Material arrives at the point of use in the same clean condition it was when placed into storage.

Herochu offers customization options through OEM and ODM service channels. While the standard models cover the most prevalent sheet sizes and weight capacities, operations with atypical material dimensions — such as 6-foot by 12-foot aluminum skins for trailer manufacturing or oversized plastic sheets for thermoforming — can obtain racks built to their exact specifications. Drawer counts, spacing between cassettes, overall height and even the inclusion of divider trays within drawers can be tailored. This configurability ensures the rack integrates as a cohesive part of the facility’s material management strategy rather than forcing compromises.

In an era where shop safety, space utilization and material accountability all contribute to competitive advantage, the Herochu material and panel storage rack for plywood, aluminum and plastics delivers measurable improvements across all three dimensions. It is not merely storage furniture; it is an engineered handling solution that reconfigures how heavy sheet goods move into, through and out of a facility. From the first drawer opened in the morning to the last restock of the afternoon shift, the rack quietly pays for itself in reclaimed floor space, reduced damage and faster throughput.

The Digital Backbone: PLC and Software Integration

Solving the “Chaotic Inventory” Problem

The “Standard Model” vs. Herochu Customization

Enhancing Material Flow

Conclusion

Not every metal fabrication facility requires the complexity or capital investment of fully automated vertical lift systems. For shops storing large volumes of identical sheet sizes—coil-fed operations with surplus cut-to-length plates, service centers holding monthly buffer stock, or heavy plate fabricators working with limited variety—standard model plate steel racks for sheet metal storage provide proven, cost-effective high-capacity sheet metal storage without motors, sensors, or software updates. Herochu’s standard racking line bridges the gap between improvised floor stacking and full automation, offering engineered durability at a fraction of the cost.

The Unseen Costs of Floor Stacking and Why Racks Win

Many shops default to stacking sheets directly on concrete floors, separated by wooden battens or plastic dunnage. This practice appears inexpensive initially but carries hidden expenses: sheets at the bottom of a stack suffer edge damage from overhang, surface scratches from shifting loads, and permanent bending from uneven weight distribution. Retrieving a sheet from the middle of a five-ton stack requires a forklift driver to carefully extract it while balancing the upper layers—a slow, dangerous maneuver that frequently damages both the retrieved sheet and those remaining.

Herochu’s standard model plate steel racks eliminate these problems through cantilevered arm designs that support each sheet individually. Constructed from hot-rolled structural steel with full-penetration welds, these racks hold each plate in a dedicated position, allowing any sheet to be accessed directly without disturbing others. The open-front cantilever configuration also enables side-loading from a forklift without requiring the truck to enter the rack structure, reducing collision risks.

Capacity Configurations for Real-World Inventories

Herochu offers three standard series of high-capacity sheet metal storage racks:

• Series HCS-3000: Designed for light-gauge sheets up to 3,000 mm long and 3,000 kg per arm. Ideal for HVAC shops, sign fabricators, and automotive stamping suppliers.

• Series HCS-5000: Mid-range capacity handling 5,000 kg per arm with 5,000 mm length. Common in general fabrication, shipyard subcontractors, and structural steel shops.

• Series HCS-8000: Heavy-duty units rated for 8,000 kg per arm and 8,000 mm length, used by pressure vessel manufacturers, mining equipment fabricators, and large service centers.

Each rack features adjustable arm spacing on 100 mm centers, allowing reconfiguration as inventory changes. Floor anchors secure the structure against seismic or impact loads, and optional back stops prevent sheets from sliding through. For shops with unusually wide plates, Herochu provides custom arm extensions up to 3,000 mm projection.

Integrating Standard Racks into a Productive Workflow

While automated tower storage system for sheet metal plates excels in high-mix, low-volume environments, standard model plate steel racks shine in high-volume, low-mix scenarios. A typical application: a plate processing center that receives weekly shipments of 12 mm, 16 mm, and 20 mm mild steel in 6,000 mm lengths. The shop dedicates one rack to each thickness, arranges racks in a U-shaped layout around a central forklift aisle, and color-codes arm positions for first-in-first-out (FIFO) rotation.

This configuration, when combined with a simple inventory log or barcode system, achieves retrieval times of 90–120 seconds per sheet—fast enough for many operations and significantly better than floor stacking. The capital cost per storage position is roughly one-tenth that of an automated vertical tower, making standard racks the rational choice for shops where throughput does not justify automation.

Durability Engineered for Decades of Service

Herochu builds every steel plate storage tower in its standard line with a 2.5:1 safety factor against rated capacity. Arm deflection under full load stays below L/200 (where L is arm length), preventing the “sag” that causes sheets to slide off over time. All exposed surfaces receive a three-step coating: sandblasting to SA 2.5, zinc-rich epoxy primer, and a polyurethane topcoat resistant to cutting fluids, oils, and welding spatter. For shops in corrosive environments—coastal areas or chemical plants—Herochu offers hot-dip galvanizing as an upgrade.

Field data from Herochu installations shows standard racks operating without structural failure for 25+ years, with only occasional replacement of plastic wear pads or rubber bumpers. This longevity drives a total cost of ownership that often undercuts cheaper imported racks, which may use thinner steel or inferior welds that fail within a decade.

When to Choose Standard Racks Over Vertical Lift Systems

The decision between standard model plate steel racks and an automated single-tower sheet metal storage system hinges on three factors:

1. Inventory mix: Fewer than 15 distinct sizes/thicknesses favors standard racks. More than 30 favors automation.

2. Retrieval frequency: Less than 50 retrievals per shift works well with racks. Over 100 retrievals per shift justifies the speed of automation.

3. Floor space value: If square footage is abundant and cheap, racks win. If space costs exceed $15 per square foot per year, automation’s space savings often pay for itself.

Herochu’s sales engineers provide free storage audits to help shops model these variables. For many customers, a hybrid solution emerges: standard racks for high-volume common plates, plus a single-tower system for low-volume, high-variety materials.

Installation and Maintenance Simplicity

Unlike automated systems requiring certified electricians and programmers, Herochu’s standard model plate steel racks for sheet metal storage install with basic tools and a laser level. Anchoring to a 4-inch reinforced concrete floor with 5/8-inch epoxy bolts takes one day for a six-rack array. Maintenance consists of annual torque checks on bolts, visual inspection for weld cracks, and replacing worn arm bumpers every three to five years.

For shops committed to lean manufacturing but not yet ready for full automation, Herochu’s standard racks deliver reliable high-capacity sheet metal storage with minimal overhead—proving that sometimes the most advanced solution is simply a well-built steel rack.

In the realm of industrial material handling, a standardized, one-size-fits-all approach frequently results in compromise. Factory layouts differ, crane capacities vary, and the dimensional characteristics of raw materials are unique to each operation. Recognizing this, Herochu has positioned itself not merely as a vendor of steel racks but as a provider of engineered storage systems tailored to the specific, heavy-duty requirements of the client. The Herochu Custom Heavy Duty Sheet Metal Storage Rack System is the definitive answer for operations where off-the-shelf solutions fail to meet the demands of weight, space, or workflow.

The customization process with Herochu begins with the material itself. The company understands that a facility processing thin aluminum flashing has different storage requirements than a forge processing 6-inch thick steel blanks. Consequently, the weight capacity per layer is a primary variable. While the baseline Herochu system handles 3 tons per drawer with ease, the custom engineering department regularly produces racks rated for 10, 15, and up to 20 tons per layer. Achieving this level of heavy-duty performance requires more than just thicker steel; it involves a re-engineering of the undercarriage, the integration of industrial-grade roller bearings, and the reinforcement of the track alignment to ensure that even at maximum load, the drawer remains perfectly true and operable via the selected extension method—be it manual, electric, or automatic.

Plate size is another critical dimension where Herochu‘s custom capabilities shine. Standard industrial plates often come in 4×8 or 5×10 foot configurations, but modern laser cutting beds and press brakes often accommodate far larger sheets. The Herochu custom rack system is designed to house and protect sheets up to 6000*2000mm. When dealing with material of this length, deflection becomes the enemy. Herochu engineers counter this by incorporating intermediate support beams within the drawer bed, ensuring that long sheets remain perfectly flat and supported across their entire span. This prevents the “sag” that can cause issues with automated feeding systems on high-end laser cutters. Additionally, the single layer height can be adjusted anywhere within the 220mm to 300mm range to optimize the air space between drawers. For a customer storing exclusively 1/4″ plate, a tighter layer height maximizes the number of storage levels available within the factory’s vertical clearance.

The Herochu Custom Heavy Duty Sheet Metal Storage Rack System also offers flexibility in the method of operation. For lighter applications or smaller shops where capital expenditure is a concern, manual pulling provides a cost-effective and reliable means of access. The drawer wheels are precision-ground to ensure smooth rolling even with loads up to several tons. For heavy plate processing facilities where 20-ton drawers are the norm, Herochu integrates electric extension mechanisms. These motorized drives allow a single operator to extend a fully loaded, 6-meter long drawer with the push of a button, eliminating the physical strain and risk associated with moving such mass manually. For fully automated warehouse environments, the system can be configured for integration with automated crane control systems, enabling seamless picking and placing of sheets as part of a lights-out manufacturing cell.

The modular nature of the Herochu custom system extends to the number of layers. While the common configurations are 5+1, 6+1, and 8+1, Herochu works directly with facility planners to maximize cubic density. If a building has a 40-foot clear height hook, a 10+1 layer Herochu rack can be designed and certified to utilize that entire volume safely. Each additional layer translates to fewer square feet of floor space wasted on storage. The “plus one” floor layer is often utilized for offcut storage or for housing the vacuum lifter attachment when not in use.

Security and longevity are guaranteed through the Herochu build quality. All racks carry ISO9001 and CE certification, confirming that the manufacturing processes and the structural calculations meet international safety standards. The finish is a durable industrial enamel designed to resist the scratches and corrosive environments common in metalworking shops. Furthermore, Herochu provides comprehensive support from the initial site survey through to installation. With a delivery cycle of 30 days for most custom orders, the lead time is competitive. Upon arrival, clients can choose between Herochu‘s on-site installation team, who ensure the rack is erected level and true, or they can utilize the company’s online guidance and documentation for self-installation, a flexibility that allows the project to fit the client’s timeline and budget. For those seeking a storage solution that fits their operation like a precision-machined component, the Herochu Custom Heavy Duty Sheet Metal Storage Rack System is the definitive choice.

The modern metalworking shop faces a persistent logistical challenge: the efficient and safe storage of large-format sheet stock. Whether handling thin-gauge aluminum prone to warping or heavy 6-meter steel plates weighing several tons, improper storage leads not only to material damage and inventory chaos but also to significant safety hazards and wasted labor hours. In environments where floor space is at a premium and throughput dictates profitability, the conventional method of leaning sheets against walls or stacking them haphazardly on timber dunnage is no longer viable. This is where the engineering precision of Herochu Roll-Out Steel Plate Shelves redefines operational workflow.

Herochu has engineered a horizontal storage solution specifically designed to address the rigorous demands of metalworking shops dealing with steel, stainless steel, aluminum, and galvanized sheets. The primary objective of this system is the elimination of “double handling” and the reduction of retrieval time to mere seconds. At the core of this system lies the principle of 100% extendable drawers. Unlike static cantilever racks or vertical storage bins where the operator must struggle to access the rear or middle of the stack, the Herochu roll-out mechanism brings the entire payload of the drawer safely outside the rack footprint.

The construction of these roll-out steel plate shelves is rooted in heavy-duty structural integrity. The frame is fabricated from high-tensile structural steel, welded and bolted to withstand the immense inertia generated when moving a fully loaded drawer. Given the specific parameters of the metalworking sector, Herochu offers a range of customizable sizes to accommodate standard and non-standard sheet dimensions. The system easily handles plate sizes of 2000*1500mm, 3000*1500mm, 4000*1500mm, and extends to the substantial lengths of 6000*1500mm and even 6000*2000mm. For a shop specializing in laser cutting or press brake forming, having these large plates stored flat on dedicated shelves ensures that the material remains flat and stress-free, preventing the bowing that often occurs when sheets are stored vertically over long periods.

One of the most critical aspects of this Herochu storage system is the weight capacity configuration. The standard offering supports up to 3 tons per drawer; however, recognizing that many industrial metalworking shops deal with thick plate or die steel, Herochu provides customization for weight capacities ranging from 1 ton up to a staggering 20 tons per layer. This is achieved through reinforced undercarriage beams and specialized heavy-duty wheel assemblies mounted directly into the drawer chassis. The wheels are not mere casters; they are forged steel rollers operating within a precision track system that ensures smooth manual or electric actuation even under maximum load. This heavy-duty engineering ensures that the Roll-Out Steel Plate Shelves remain a permanent, reliable fixture in the shop for decades.

The integration of these shelves into a metalworking environment significantly compresses labor time. The design allows for seamless combination with overhead lifting equipment. An operator can use a bridge crane, jib crane, or a vacuum lifter to access any single sheet within the rack. Because the drawers extend 100% outside the frame, the lifting device has a clear, unobstructed path to the material. There is no risk of the sling or vacuum pad snagging on the rack structure itself. This feature transforms material handling from a two-person, fork-dependent job into a precise, single-person operation. The worker simply opens the pivoting doors of the Herochu rack, pulls out the desired drawer containing the specific gauge and alloy required for the job, and the sheet is immediately available for transport to the laser cutter, shear, or welding bay. Once the sheet is removed, the drawer is pushed back into its compact, secure housing, protecting the remaining inventory from shop dust and accidental collision with forklifts.

Safety is a paramount concern in any metalworking shop, and the Herochu design reflects this with several fail-safe features. The pivoting doors secure the front of the rack, preventing loose sheets from sliding forward during seismic events or accidental bumps. Furthermore, the drawer extension mechanism incorporates a locking feature that prevents the drawer from being accidentally dislodged from the track. When fully extended, the system maintains a specific counterbalance ratio to prevent tipping, a crucial engineering calculation that distinguishes a purpose-built industrial rack from a generic shelving unit. The single-layer height, adjustable between 220mm and 300mm, is optimized to store a variety of sheet thicknesses without wasting vertical cubic space. This vertical optimization means a shop can store up to 10 or more layers of distinct material types (e.g., Layer 1: 1.5mm CR Steel; Layer 2: 3.0mm Aluminum; Layer 3: 2.0mm Stainless 304) within the same footprint previously occupied by a single, messy pile.

For metalworking shop owners considering an upgrade to their material handling infrastructure, the Herochu Roll-Out Steel Plate Shelves represent a convergence of safety, efficiency, and space optimization. The system is backed by ISO9001 and CE certifications, ensuring that the manufacturing process and the final product meet stringent international standards for quality and safety. Whether opting for manual pulling in a small job shop or electric extension for heavy-gauge plates in a high-volume facility, Herochu provides a tailored solution. The company also offers comprehensive support with a 30-day delivery cycle and the option for on-site installation or detailed online guidance, ensuring that the transition to a more organized, productive, and safer metalworking environment is seamless and professionally executed.

• Medium Duty (1,000 – 2,000 kg/layer): Ideal for thinner gauge metals, aluminum sheets, and smaller workshops.
• Heavy Duty (2,000 – 5,000 kg/layer): The standard for most steel service centers and laser cutting facilities.
• Extra Heavy Duty (5,000 – 10,000 kg/layer): Designed for thick steel plates, shipbuilding materials, and large-scale infrastructure projects.

1. Anti-Overturning Devices: The most critical safety feature is the prevention of drawer tip-over. When a heavy drawer is pulled out, the center of gravity shifts. Our system uses sliding guide rails and mechanical locks to ensure the drawer remains stable and cannot be pulled out beyond its safe limit.
2. Foot Roll Protection: The base of the rack is equipped with protection devices to prevent forklifts from colliding with the uprights, which could compromise the structural integrity.
3. Safety Locks: Each drawer can be equipped with a safety pin or lock to prevent accidental opening during transport or seismic events.
4. Floor Anchoring: The racks are designed to be bolted to the floor using high-strength expansion bolts, anchoring the system to the building’s foundation.

• 100% Accessibility: Every sheet is instantly accessible. There is no need to unstack materials.
• Single-Person Operation: The ball bearing rails make it possible for one person to pull out a 2-ton drawer with ease. This reduces labor costs and improves safety by removing the need for constant forklift intervention in the storage area.
• Material Protection: The drawers can be fitted with continuous trays or inclined supports. This keeps the sheets flat and prevents them from rubbing against each other, which eliminates scratches and burrs. This is particularly important for laser cutting, where surface imperfections can ruin a finished part.

1. Shot Blasting: Removing rust and mill scale from the raw steel.
2. Phosphating: Creating a chemical bond for the paint.
3. Electrostatic Powder Coating: Applying a durable polymer layer

Warehouse managers face a constant pressure: store more material in the same footprint while maintaining safety and accessibility. The High Density Sheet Metal Rack System answers this challenge through a multilayer drawer configuration that transforms unused vertical airspace into organized, accessible storage. Designed for heavy duty warehouse storage applications, this rack system condenses what would require 800 square meters of floor stacking into a 100 square meter footprint.

Professional Manufacturing of 8-Layer Drawer Type Metal Sheet Racks

The core innovation is the drawer type rollout mechanism applied across up to eight storage layers. Unlike cantilever racks where each arm requires dedicated aisle space, this system uses a single central aisle. Each drawer extends perpendicular to the aisle, allowing one forklift position to serve all eight layers without repositioning.

Professional manufacturing processes distinguish this rack from generic industrial shelving. The frame begins with laser-cut Q235 steel plates, formed on CNC press brakes to ensure precise 90-degree angles. All weld joints are robotically welded with full penetration, then ultrasonically tested for void detection. A five-stage wash system (alkaline clean, rinse, acid etch, rinse, zirconium conversion coating) prepares the surface before powder coating. The coating itself is applied by automated reciprocators that maintain consistent film thickness on complex geometries.

The result is a rack system certified for dynamic and static loads. Dynamic loads—those experienced during drawer extension—are often the failure point for cheaper racks. This system’s guide rails incorporate hardened steel balls running in induction-hardened raceways, rated for 50,000 extension cycles at full capacity.

Extreme Load Capacity from 1000 to 10000 KGS

Heavy duty warehouse storage demands flexibility. One bay might store 1000kg aluminum sheets for aerospace components; the adjacent bay might hold 10,000kg steel armor plate. This rack system accommodates that range without modification to the basic structure.

At 1000kg capacity, the standard ball bearing rail system with 4mm wall thickness is sufficient. As capacity increases to 5000kg, the rail profile switches from C-channel to box section with internal rollers. For 10,000kg applications—which require engineering consultation—the drawers ride on dual tandem wheels running on hardened steel tracks, similar to industrial drawbridges. The pull mechanism changes from manual to electric extension or automatic hydraulic assist.

The 8-layer configuration deserves special attention for weight distribution. When all eight drawers are loaded to capacity, the total stored weight can reach 80,000kg. The rack’s foot plates spread this load across a floor area of typically 2.5m x 6m, resulting in a floor pressure of approximately 53,000 kg/m². Warehouses with reinforced concrete slabs (minimum C25 grade) handle this easily, but older facilities may require load-spreading mats or additional foot plates.

Material Protection and Safety Features

High density storage increases the risk of sheet damage because materials are stored in closer proximity. This rack system mitigates that risk through several engineered features:

Inclined Plastic Supports: Each drawer tray incorporates continuous plastic support bars angled at 5 degrees toward the rear. This inclination prevents stored sheets from sliding forward when the drawer is extended. The plastic material is a glass-filled nylon with hardness rating Shore D 85—hard enough to resist cutting from sheet edges but soft enough to avoid scratching painted or polished surfaces.

Safety Against Overturning: Sliding guide rails include a positive stop mechanism that engages automatically at 90% extension. A foot roll protection device—a spring-loaded roller that contacts the floor—prevents the rack from tipping forward when heavy sheets are at the drawer’s outer edge. This device is critical for 8-layer systems where the center of gravity shifts significantly during loading.

Anti-Scratch Edge Protectors: All drawer edges are fitted with replaceable UHMW polyethylene strips. These protect both the stored sheets and the operator. For laser-cut sheets with sharp burrs, the protectors prevent the burrs from gouging the drawer surface.

Forklift Compatible Design for Efficient Loading

Despite the drawer mechanism, the primary loading method remains forklift operation for most facilities. The rack design acknowledges this: each drawer has a recessed fork pocket that guides the forklift tines to the correct insertion depth. The pocket is reinforced with 10mm steel plate to withstand accidental over-insertion.

For high density warehouses, the system supports a “batch pick” workflow. The operator extends the required drawer, drives the forklift tines into the pocket, lifts the entire drawer’s contents (or individual sheets), and withdraws. Because the drawer remains attached to the rack during loading, there is no risk of the drawer tipping off the forks—a common hazard with removable tray systems.

Optional electric extension motors can be specified for drawers exceeding 5000kg. These motors, controlled by a pendant or remote, extend the drawer at a controlled 5mm per second, preventing sudden movements that could destabilize the load. An automatic extension system with photo-eye sensors is available for facilities integrating with warehouse management software.

Custom Layers and Delivery

While 8-layer is the headline configuration, the manufacturing process supports any combination from 3 to 12 layers. The limiting factor is the ceiling height: each layer requires 300-350mm of vertical clearance including drawer structure and sheet bundle height. A 5+1 configuration (5 drawers plus top fixed shelf) is common for facilities with 3-meter ceilings.

Delivery cycle for custom 8-layer systems is 30 working days from approved drawings. Installation is performed on-site by the manufacturer’s team, typically requiring 2-3 days for a multi-bay system. The installation includes floor anchoring, laser alignment of rails, and cycle testing of every drawer under partial load.

Certifications include ISO9001 for quality systems and CE marking for mechanical safety. For warehouses in seismic zones, additional base isolation kits are available as an OEM option.
