Steel bars and angle iron share a storage challenge: both are long, both are heavy, and both arrive at the warehouse in mixed bundles that resist tidy segregation. The Herochu High-Density Cantilever Storage Rack solves the organization problem through independent tier compartments and a telescopic arm system that delivers each storage level to the operator without repositioning the rack or widening forklift aisles.
High-Density Storage Concept
High density in long-material storage means more material per square meter of floor area—without stacking that crushes lower tiers or burying slower-moving stock behind faster-moving product. The Herochu rack achieves this density through two design features working together.
First, the telescopic cantilever arms retract flush with the column face when not in use. Adjacent racks sit close together in the retracted state, compressing the storage row footprint. Second, independent compartments at each tier let operators assign specific material grades or dimensions to individual storage levels. Angle iron in 3-meter lengths on one tier, round steel bars in 6-meter lengths on the next—each accessible without unloading the other.
This per-tier independence eliminates the “dig down” problem: retrieving a specific bar from the bottom of a mixed stack on a fixed rack requires removing everything above it first.
Telescopic Arm Drive and Operation
Each tier’s arms connect to a gear-and-rack drive train activated by a hand crank. One full crank rotation extends the arm by a measured increment—70% to 99% of retracted length at full extension. The operator cranks the target tier outward, retrieves or loads material directly from the extended arms, then retracts the tier back into the rack body.
No electricity required. No hydraulic fluid. No control panel programming. The manual crank drive suits facilities with moderate access frequency—building material yards, metal service centers, small to mid-sized fabrication shops—where the cost and maintenance of powered storage systems outweigh their speed advantage.
Load Capacity and Structural Design
The Herochu frame is fabricated from Q235B high-strength steel. A dual-beam crossbar connects column assemblies across the rack width, providing the structural rigidity needed when extended arms carry full-rated loads far from the column face.
Each arm carries up to 500 kg. Per-level capacity reaches 3,000 kg on the HC-G6053 and HC-G6053S models and 5,000 kg on the HC-G9065 and HC-G12065 models. These ratings accommodate dense bundles of steel bars and angle iron:
- Round steel bars up to 12 meters
- Square and flat bars in bundled form
- Equal and unequal angle iron
- Seamless and welded steel pipe
- Copper and brass round rods
Space Recovery and Aisle Elimination
Fixed cantilever racks require forklift aisles of 3.5 to 4 meters between rows. The Herochu telescopic design eliminates that aisle requirement—arms extend outward to the operator, material is handled directly, then the tier retracts. In the retracted state, adjacent rack rows sit close together, reclaiming over 30% of the floor area compared to fixed-arm configurations. For warehouses where expansion is not an option, this recovered space accommodates additional storage rows or processing zones.
Material Segregation and Damage Reduction
Steel bars and angle iron stored in mixed bundles on shared arms suffer surface damage from hard-edge contact. Galvanized angle iron pressed against black steel round bar transfers zinc marks; round bars stacked on angle edges develop flat spots under load.
The Herochu rack’s independent tier compartments prevent this contact. Each level stores a single material type—arms configured for angle iron hold angle iron only; arms configured for round bars hold round bars only. The 600 mm clear space between arms, customizable at the factory, sets the storage geometry to match the material.
Powder Coating and Service Life
Every structural component receives powder coating after welding. The coating protects the Q235B steel frame from atmospheric and chemical corrosion and provides a smooth contact surface that will not transfer oxidation to stored material—reducing rework before issue.
Model Configurations
| Model | Max Material 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) |
The HC-G6053S handles 6-meter stock at 3,000 kg per level—suited to standard bar and angle lengths. The HC-G12065 accommodates 12-meter material at 5,000 kg per level for long-bar service centers handling full-length stock. Tier count and arm spacing adjust at the factory to match the customer’s material inventory profile.
CE Certification and Pre-Shipment Verification
The Herochu high-density cantilever rack carries CE certification. Each unit undergoes pre-shipment load testing to verify that the frame supports rated capacity without deflection exceeding design tolerance. This testing provides documented verification for safety audits and equipment acceptance protocols before the rack enters service.
Summary
High-density storage of steel bars and angle iron requires structural capacity, organized segregation, and aisle-free access. The Herochu High-Density Cantilever Storage Rack combines a Q235B dual-beam frame, manually cranked telescopic arms, and independent tier compartments to deliver dense, organized, mechanically simple storage for metal service centers and fabrication facilities managing mixed long-material inventory.
