Multi-drawer Metal Panel Warehouse Storage Rack

Most sheet metal inventory problems are retrieval problems wearing a disguise. The material is there. The stock record is roughly right. What fails is the last three meters: finding the 1.5 mm panel that was cut last month, checking whether it is still flat, and getting it out without shifting 40 sheets on top of it.

A multi-drawer metal panel warehouse storage rack attacks that specific failure. Instead of one deep pile, the rack divides the bay into horizontal drawers, each of which can hold a different thickness, alloy or job number. The result is an inventory you can read by looking, not by lifting.

Why classification beats volume

Volume-based storage assumes all panels are interchangeable. In a job shop they are not. A single bay might hold 0.8 mm galvanized, 2 mm cold rolled, 3 mm aluminum and a set of pre-painted blanks for one customer. Flat-stacked together, those become one pile with no visible boundary.

Drawer-based classification changes the physical layout to match the material record. Each drawer holds one SKU or one job, and the label sits on the drawer face at eye level. Three practical gains follow:

• Retrieval stops being a search. The operator walks to a labeled drawer, not a 4-tonne stack.
• Damage is contained. A bent corner on one drawer cannot crush the panel below it.
• Counting becomes visual. An empty drawer is an obvious signal, which is what makes low-stock warnings honest.

Herochu builds these racks with up to six layers as standard and custom layer counts on request, so the drawer count can match your actual SKU spread rather than the nearest catalog size.

The narrow-aisle advantage

Panel storage is usually the equipment that eats the most floor area per tonne stored. A multi-drawer rack is a way to buy that area back.

Drawers extend horizontally instead of requiring a forklift approach from three sides, so the rack can be placed along a wall or between production cells where a standard cantilever or A-frame would not fit. In tight footprints, drawers opening into a single service aisle let you stack racks back to back and still reach every layer.

Herochu quotes a space utilization rate of 100% and a storage density increase of 150% for this configuration compared with flat floor stacking. The mechanism is simple: vertical stacking above 1.5 m is normally wasted, and a drawer tower uses it.

What the drawer hardware has to do

Three components decide whether a multi-drawer rack stays usable after two years of production.

Roller track. A 2000 kg tray on bare steel slides needs two people and a lever. On a roller track it moves by hand with a fraction of the force, which is the difference between a rack that is used and a rack that is bypassed. Herochu rates drawer pull at 500–2000 kg per layer by hand.

Limit device. Stops the tray at the safe extension point. On a multi-drawer unit, one over-extended tray can obstruct the aisle or tip the frame, so the stop has to be mechanical and repeatable.

Lock. Holds the drawer closed during crane work above the rack or during forklift traffic alongside it. Vibration is enough to walk an open drawer out.

The frame behind those parts is thick welded carbon steel with a zinc base and double anti-corrosion coating, finished light blue. That coating is not cosmetic: panel storage bays sit next to cutting and deburring operations where oil mist and moisture settle on every horizontal surface.

Sizing a multi-drawer unit

A common configuration for a mixed-inventory shop is four layers at 3000 mm width for short offcuts plus two 6000 mm layers at the base for full sheets. Drawer widths can vary by layer, which is the point of building to order rather than buying a fixed unit.

Integrating the rack with cutting equipment

Drawer racks sit naturally upstream of a laser or plasma table because the drawer presents the sheet horizontally at a workable height. If the rack is being specified as part of a line rather than as standalone storage, Herochu’s automated version adds a PLC, touch screen and alarm system, with MES integration to schedule which drawer serves which nest.

The same platform is used in Herochu’s laser cutting automatic loading and unloading storage systems. That continuity matters at upgrade time: a manual rack today can be extended into an automated bay later without redesigning the floor layout.

Typical users are building material shops holding coil-fed cut lengths, manufacturing plants running mixed-thickness production, and machinery repair shops where the drawer label is the only reliable record of what is actually in stock.

Questions buyers ask about multi-drawer panel racks

How many drawers should a shop start with? Match the drawer count to distinct panel SKUs you touch weekly, not to total inventory. Four to six layers covers most job shops.

Can drawers hold different panel sizes? Yes. Width and depth can be set per layer within the 800 × 800 mm to 6000 × 2000 mm envelope.

Is 3000 kg per layer enough for steel plate? It covers most 6-meter sheet in the 3–8 mm range. Thicker plate should be quoted at 4000 kg per layer with a heavier frame.

How do operators reach the top drawer? The top layer sits within reach of a standing operator on a standard 2100 mm unit; taller frames with six layers are loaded by crane or vacuum lifter from the drawer face.

Does the rack work with an overhead crane? Yes. The drawer opens clear of the frame so a sling or vacuum lifter can lift straight up without fouling the layer above.

Herochu service package

Herochu supports the project before steel is cut: graphic design and 3D model design to check the rack against your layout, online technical support during commissioning, free spare parts, and a 5-year warranty with return and replacement service.

Send the panel list, the shift throughput and the available footprint. The drawer count, layer heights and frame depth follow from those three inputs.
