Floor space in metal fabrication facilities commands a premium. Every square meter devoted to static storage represents capacity that cannot be deployed toward production equipment, work-in-progress staging, or revenue-generating operations. Herochu’s motorized sheet metal storage system with electric drawers converts dormant vertical air into active storage density, allowing warehouses to store up to 60 percent more sheet metal in the same floor area compared to traditional cantilever racking .
The Economics of Vertical Drawer Storage
Conventional sheet storage scatters inventory across the floor in stacks, A-frames, and cantilever bays. Each format consumes aisle space that forklifts must navigate and that overhead cranes must reach across. Herochu’s drawer-based architecture eliminates the permanent aisle requirement by bringing the material to the operator rather than forcing the operator to travel to the material. Each tier functions as an independent pull-out drawer, enabling single-operator access to any sheet without disturbing adjacent stock . In facilities running multiple shifts, this selectivity compounds: the second and third shifts inherit an organized inventory rather than a depleted pile requiring reorganization before work can begin.
Heavy-Duty Load-Bearing Engineering
The structural frame uses reinforced cold-rolled steel with a dual-beam crossbar configuration. This design splits each drawer’s load between two parallel load paths, reducing deflection and maintaining smooth travel even under maximum rated capacity. Standard models support 3,000 kg per layer across six tiers, yielding a total rack capacity of 18,000 kg . Larger configurations extend to 5,000 kg per tier and total capacities approaching 30,000 kg. The hot-dip galvanized surface treatment resists rust and corrosion in factory environments where humidity, cutting fluids, and temperature variation are constant companions.
Classified Storage and Retrieval Efficiency
Multi-layer drawer separation enables systematic classification by material type, thickness, or specification. A drawer assigned to 3 mm mild steel stays dedicated to that material; a separate drawer holds 5 mm stainless; a third accommodates aluminum blanks. Label slots on each drawer front allow instant visual identification without opening drawers or consulting inventory systems. Herochu reports that this organization reduces sheet material picking time by approximately 70 percent in field installations, a figure that translates directly into labor hours recovered per shift .
Safety and Ergonomic Design
Industrial-grade ball bearing slide rails guarantee smooth pull-out and push-in with minimal effort, even when drawers carry multi-ton loads. A safety lock mechanism prevents accidental drawer sliding during loading and unloading, addressing the most common accident pattern in drawer-based storage: a drawer that moves while a crane hook or forklift tine is within the load envelope. The motorized drive option further reduces physical strain by eliminating manual cranking entirely. Remote control operation allows the operator to stand at the optimal position for load engagement rather than at the drawer face.
Modular Configuration for Evolving Operations
Herochu offers drawer counts from three to fifteen tiers, with customizable drawer dimensions to fit 4×8 ft and 5×10 ft sheet products as standard. Optional casters convert the rack into a mobile storage unit for facilities that reconfigure production lines periodically. For operations anticipating growth, bolt-on modular bays allow capacity expansion without dismantling existing racks or relocating inventory. The motorized sheet metal storage system with electric drawers represents a capital investment that adapts to changing production requirements rather than constraining them. Herochu delivers each system with CE and ISO 9001 documentation, and factory-direct engineering support ensures that the final configuration matches the material flow it was designed to serve.
