Square and rectangular hollow sections behave differently on storage racks than round pipe. Flat contact surfaces distribute weight unevenly across arm faces, and stack-bundled rectangular tubes shift under their own weight if the support points do not match their geometry. The Herochu Custom Roll-Out Cantilever Rack addresses this through tier-by-tier dimensional customization paired with a mechanical roll-out drive that brings each storage level to the operator.
Tier Customization for Section Geometry
Every storage level on the Herochu roll-out rack can be configured independently. Arm spacing, arm length, and tier height are set at the factory to match the specific cross-section dimensions of the square or rectangular pipes stored at that level. A rack storing 40×40 mm square tubing on the lower tiers can carry 200×100 mm rectangular sections on the upper tiers without mixing incompatible dimensions at the same storage position.
This per-tier independence prevents the stacking damage that occurs when operators place smaller sections on racks sized for larger stock—contact pressure concentrates on narrow edges, deforming tube walls over time. Dedicated compartments at each level keep material groups separated and sorted by size, grade, or project allocation.
Mechanical Roll-Out Drive
Each tier rolls out on a rail-type structure mounted at floor level. The hand-crank drive extends the storage deck outward—by 70% to 99% of its retracted position—without moving the rack frame. Once the tier is fully extended, operators pick material directly from the exposed face. After loading or retrieval, the tier retracts back into the rack body.
The manual crank drive requires no electricity. This makes the Herochu roll-out rack suitable for facilities where power distribution to storage zones is limited, where downtime from electrical faults must be avoided, and where maintenance staff prefer mechanical systems they can service in-house.
Load Capacity and Frame Construction
The Herochu frame uses Q235B high-strength steel with a dual-beam crossbar design. Each arm carries up to 500 kg. Per-level capacity reaches 3,000 kg on the HC-G6053 model and 5,000 kg on the HC-G9065 and HC-G12065 models, accommodating dense bundles of square and rectangular pipes.
The dual-beam crossbar is engineered to resist torsion. When a fully loaded tier rolls out, the extended weight generates moment forces at the column interface. The dual-beam design transfers those forces into the column base plate and floor anchorage, preventing arm deflection that could misalign square tubing during retrieval.
Space Recovery and Aisle Reduction
Fixed cantilever racks serving square pipe storage typically require 3.5 to 4 meter wide forklift aisles to allow side-loading equipment to approach each storage level. The Herochu roll-out design eliminates this aisle width because the storage deck itself brings material to the operator. Adjacent racks can sit closer together, recovering over 30% of the floor area that fixed-arm configurations waste.
This recovered space accommodates additional rack rows, material staging zones, or processing equipment—increasing storage density without expanding the warehouse footprint.
Surface Treatment and Durability
All welded steel components receive a powder-coated finish. The coating resists corrosion in environments where metal stock carries residual moisture, cutting fluids, or outdoor exposure during transit. Q235B steel substrate combined with the powder coat layer extends rack service life beyond what bare or painted steel delivers, reducing maintenance intervals.
Compatible Material Types
The Herochu roll-out cantilever rack stores:
- Bundled and loose square hollow sections
- Rectangular tubing in mixed dimensions
- Copper rods and brass round bars
- Aluminum extrusions and profiles
- Seamless and welded steel pipe
Independent tier compartments keep these material groups from contacting each other during storage and retrieval, preserving surface finish and preventing cross-grade contamination.
Model Configurations
| Model | Max Pipe Length (mm) | Load per Level (kg) | Default Tiers |
|---|---|---|---|
| HC-G6053S | 6,000 | 3,000 | 5 (custom) |
| HC-G6053 | 6,000 | 3,000 | 5 (custom) |
| HC-G9065 | 9,000 | 5,000 | 6 (custom) |
| HC-G12065 | 12,000 | 5,000 | 6 (custom) |
Clear space between arms is 600 mm as standard, adjustable at the factory. Tier count and vertical spacing match the customer’s inventory profile—whether the facility stores one size per rack or mixes multiple cross-sections across levels.
CE Compliance and Quality Verification
The Herochu roll-out cantilever rack carries CE certification. Pre-shipment load testing verifies that each unit holds rated capacity without structural deformation. This documented verification supports warehouse safety audits and equipment acceptance procedures.
Summary
Square and rectangular pipe storage demands racks shaped to the material, not the other way around. The Herochu Custom Roll-Out Cantilever Rack pairs per-tier dimensional customization with a manual crank drive, Q235B dual-beam construction, and independent storage compartments—giving metal service centers a compact, mechanically simple system for sorted, accessible hollow-section inventory.
