Space-Saving Workshop Steel Plate Storage Rack for 1500×3000mm Plates

Reclaiming Workshop Floor Space with Drawer-Type Storage

Floor space is the most expensive non-productive asset in a metal fabrication workshop. Every square meter occupied by ground-stacked steel plates is a square meter unavailable for laser cutters, press brakes, welding stations, or material handling aisles. Herochu’s space-saving drawer-type steel plate storage rack for 1500×3000mm plates converts horizontal stacking area into vertical storage density, freeing production floor for revenue-generating equipment.

The Space Math: 80% Reduction in Storage Footprint

Consider a workshop storing 1500×3000mm steel plates in a traditional ground stacking layout. Plates are sorted by thickness and material grade, separated by wooden dunnage, and accessed by crane from above. This configuration typically requires 100 m² of floor area for a moderate sheet inventory.

A Herochu drawer-type rack storing the same inventory occupies approximately 20 m². The rack’s vertical design—6 layers in the standard HC-B3015-63 configuration—stacks storage upward rather than outward. Each drawer slides out independently, so sheets on the bottom tier are as accessible as those on the top. The 80% floor space recovery is not a theoretical projection; it is a measured result from installations in fabrication shops that replaced ground stacking with Herochu drawer systems.

The recovered floor space can accommodate an additional laser cutting cell, a press brake, or a welding station—each generating output that pays for the rack installation within months.

Vertical Storage Density Without Accessibility Trade-offs

A common objection to vertical storage is that upper tiers become difficult to reach. The Herochu drawer system solves this with a 100% fully open drawer mechanism. Each tier extends completely out of the rack frame, presenting the full sheet surface to the operator. Whether the sheet is on the first tier or the sixth, the retrieval process is identical: pull the drawer to its lock-out position, lift the sheet with a crane or vacuum cup, and return the empty drawer to its lock-in position.

The mechanical assistance system reduces the pulling force required to extend a loaded drawer. Bearings on the guide rails carry the drawer weight, so the operator applies only enough force to start the drawer moving—the rails do the rest.

Structural Design for Dense Vertical Loading

Stacking 3,000 kg of steel plate on each of 6 tiers places significant demand on the rack frame. Herochu addresses this with Q235B high-strength steel construction and a dual-beam design. The dual-beam configuration uses two horizontal beams per tier rather than one, halving the load on each beam and reducing frame deflection. Under full load—18,000 kg of steel plate distributed across six tiers—the frame maintains structural integrity without racking, twisting, or beam sag.

Q235B steel has a yield strength of 235 MPa, making it suitable for heavy structural applications in industrial storage systems. The material selection, combined with the dual-beam engineering, gives the HC-B3015-63 a service life measured in decades rather than years.

Narrow Aisle Operation

The drawer-type design also reduces the operating aisle width required around the rack. Since drawers extend forward and sheets are lifted vertically, the rack can be placed against a wall or in a narrow bay. The only clearance needed is the drawer extension depth plus the turning radius of the lifting device.

For workshops with limited bay width, this means the rack can be installed in areas previously considered unusable for storage—between machines, along perimeter walls, or in alcoves.

Integration with Production Equipment

Herochu drawer racks are designed to feed directly into cutting and forming equipment. Sheets retrieved from the rack can be loaded immediately onto:

• Laser cutting machine tables
• Shearing machines
• Press brake beds
• Plasma cutting platforms
• CNC punching stations

By positioning the rack adjacent to the primary cutting machine, a single operator can pull a sheet from the drawer, rotate it onto the machine table with a vacuum lifter, and begin the cutting program without waiting for crane scheduling or a second worker’s assistance.

Frequently Asked Questions

How much floor space does a Herochu drawer rack save compared to ground stacking? A Herochu drawer-type rack reduces storage floor space by 80%. A typical ground stacking layout requiring 100 m² can be replaced with a 20 m² rack installation storing the same sheet inventory.

How does the drawer mechanism work? Each tier is a fully extendable drawer mounted on bearing guide rails. A mechanical assistance system reduces pulling force. Lock-in and lock-out positions secure the drawer during storage and material handling operations.

What is the maximum load per drawer level? For 1500×3000mm plates (HC-B3015-63 model), the maximum load per level is 3,000 kg. For larger plate sizes, the HC-B4020-65 and HC-B6020-65 models support 5,000 kg per level.

Can the rack be placed against a wall? Yes. Since drawers extend forward and sheets are lifted vertically, the rack can be positioned along walls or in narrow bays. The required operating clearance is the drawer extension depth plus the lifting device’s turning radius.

What steel is used in the rack frame? Herochu drawer racks use Q235B high-strength steel with a dual-beam design. Q235B has a yield strength of 235 MPa, suitable for heavy industrial storage applications.

Summary

Herochu’s space-saving steel plate storage rack for 1500×3000mm plates delivers an 80% reduction in storage floor space by converting horizontal stacking into vertical drawer-type storage. The Q235B dual-beam frame supports 3,000 kg per level across 6 tiers. Fully extending drawers with mechanical assistance and lock-in/lock-out positioning make every tier equally accessible. For workshops where floor space is at a premium, this rack system returns usable production area while improving material handling speed and sheet condition.
