Warehouse managers handling heavy metal inventory face a persistent challenge: how to store large, dense sheets without sacrificing accessibility. Herochu answers with the Heavy Duty Full Extension Rack Warehouse Rack, a storage system that combines industrial steel construction with 100% drawer extension. Unlike static pallet racks that require forklifts to dig through stacks, this rack allows direct access to any stored sheet from above or from the front.

The core innovation is the drawer tray mechanism. Each tray slides out completely on load-bearing ball bearing rails, revealing the entire sheet surface. Overhead cranes or forklifts with suction lifters can then extract the material without contacting adjacent sheets. This full extension capability eliminates the need to unstack multiple layers, cutting retrieval time by 70% compared to floor storage.

Herochu builds these racks for extreme duty. The frame uses reinforced columns and precision-welded crossbeams. Carbon steel construction provides inherent strength, while a powder coated finish adds corrosion protection. Each drawer tray supports up to 5000 kg. Racks come in configurations from 4 to 8 layers, with total load capacities reaching 40 metric tons for 8-layer models. Layer lengths adjust from 2.5 to 6 meters, accommodating standard sheet sizes used in automotive, aerospace, and general fabrication.

The term “heavy duty” in warehouse racking often gets overused. Herochu defines it specifically: the rack withstands daily loading by 5-ton forklifts, resists impact from sheet edges, and maintains alignment over decades of service. The ball bearing rails undergo cycle testing to 50,000 operations without performance degradation. Anti-tip safety devices include foot rollover protection and rail stops. When fully extended, the drawer remains stable and level, even with 5000 kg on board.

Warehouse applications extend beyond laser cutting. Stamping plants use these racks for die and mold storage. Service centers store aluminum and stainless sheets. Shipyards organize steel plates for hull construction. Any facility that handles flat metal stock benefits from the organization and accessibility of the Herochu full extension system.

Space efficiency is a major selling point. A typical warehouse storing sheets on the floor uses 100% of the footprint for active material. With a 6-layer Herochu rack, the same footprint holds six times the inventory, or alternatively, 83% of the floor space becomes free for other uses. Vertical storage also improves safety: no leaning stacks, no unstable piles, no sheets sliding off forks. The rack contains each load within defined drawer boundaries.

Installation requires planning. Herochu provides detailed layout drawings showing anchor points, clearance zones, and load distribution. The racks bolt to concrete floors using expansion anchors. Multiple racks can be installed side by side with shared columns, creating a continuous storage wall. Aisle widths depend on handling equipment: for overhead cranes, 1 meter of clearance at the rack front suffices; for forklifts, allow 3 meters for turning.

Maintenance procedures are simple. Clean the ball bearing rails quarterly using compressed air and a dry lubricant. Inspect the powder coated finish for chips; touch up any damage to prevent rust. Check anchor bolts annually. The steel structure itself requires no maintenance beyond visual inspection for weld cracks—a rare occurrence with Herochu construction standards.

Compared to cantilever racks, the full extension design offers better material protection. Cantilever arms leave sheets exposed to dust and impact. Drawer trays shield the bottom sheet from floor debris and protect edges from forklift collisions. The powder coated surfaces also prevent galvanic corrosion when storing dissimilar metals.

Warehouse organization improves dramatically with Herochu racks. Each drawer can be assigned a specific material grade, thickness, or customer job. Inventory counts become visual: open a drawer, see what’s left. This transparency reduces overordering and minimizes leftovers that turn into scrap. Some warehouses color-code drawer fronts or use magnetic labels for quick identification.

For warehouses integrating laser cutting machines, the Heavy Duty Full Extension Rack doubles as a just-in-time feeder. Sheets move from storage drawer directly to laser bed via overhead crane. No intermediate staging. No manual handling. The rack’s 6-meter length accommodates full parent sheets, eliminating the need for pre-cutting.

Cost justification is straightforward. A Herochu rack that occupies 20 square meters of floor space but stores 120 square meters of sheet metal (six layers) effectively recovers 100 square meters.  Add labor savings from faster retrieval, reduced material damage, and improved safety, and payback often falls under one year.

In summary, the Heavy Duty Full Extension Rack Warehouse Rack from Herochu delivers industrial-strength storage with full accessibility. Its carbon steel frame, powder coated finish, precision ball bearing rails, and anti-tip safety make it the go-to choice for warehouses storing heavy flat materials. Whether for laser cutting, stamping, or metal distribution, this rack system optimizes space, protects inventory, and speeds material flow.
