Horizontal sheet metal storage rack

If you walk into a timber yard or a steel service center selling pipes and beams, Cantilever Racks are the undisputed kings. They are brilliant for long, rigid items. However, many metal fabricators make the mistake of adopting this same system for storing flat metal sheets. It seems like a logical choice, but it is often a costly compromise.

Cantilever systems force you to stack bundles of sheet metal on top of each other between the arms. This creates a “Last In, First Out” (LIFO) nightmare. To get to the bottom sheet, you have to move everything on top. A Opslagrek van plaatstaal with roll-out drawers is purpose-built for flat inventory, giving you the selectivity that cantilever arms simply cannot provide.

The “Sag” Effect: Why Support Matters

Cantilever racks support materials at specific points (the arms). While a heavy H-beam won’t deflect between these points, a 1mm or 2mm sheet of aluminum certainly will. Over time, sheets stored on cantilever arms without a full deck can develop a permanent “sag” or warp between the support arms.

When you feed a warped sheet into a high-speed laser cutter, you risk head crashes and cut quality issues. Our Roll-Out Racks feature a fully supported steel frame drawer. Your sheets lie perfectly flat, fully supported across their entire length and width. This ensures that the material you pull out is as flat as the day it was delivered, ready for precision processing.

Accessibility: Forklift vs. Ergonomics

Retrieving a single sheet from a high cantilever shelf is a high-risk operation. It almost always requires a forklift and a spotter, and often involves dangerous “sheet dragging” to separate materials. It limits your ability to pick just one item.

In contrast, a roll-out drawer system brings the material out into the aisle. The entire drawer extends, exposing 100% of the sheet surface. This allows you to use an overhead crane or vacuum lifter to pick a single sheet gently, without any sliding or friction damage. It turns a complex forklift maneuver into a simple, safe lifting operation.

Comparison: Cantilever Racks vs. Roll-Out Sheet Racks

Functie Draagarmstellingen Roll-Out Sheet Rack
Best Application Long goods (Pipes, Tubes, Beams). Flat goods (Steel Plates, Sheets, Remnants).
Selectiviteit Low. Buried stock requires unstacking. 100%. Instant access to any drawer level.
Material Support Point support (Arms). Risk of sagging. Full support (Frame/Grid). Sheets stay flat.
Ruimte-efficiëntie Medium. Requires wide aisles for forklift turning. High. Compact footprint, crane-compatible.

Handling the “Ugly” Inventory: Remnants

One area where cantilever racks fail miserably is offcut (remnant) storage. You cannot safely balance a half-cut sheet across two cantilever arms. As a result, valuable remnants end up on the floor or in scrap bins.

A roll-out drawer acts like a tray. You can throw a 1-meter offcut, a 2-meter strip, and a full sheet all in the same drawer. They are secure, visible, and retrievable. This capability alone can save thousands of dollars a year by encouraging your team to use existing scrap instead of cutting fresh sheets.

Veelgestelde vragen

1. I already have cantilever racks. Can I retrofit them?
Unfortunately, cantilever arms are not designed to accept roll-out drawers due to the specific torque and load dynamics. However, our racks are modular and can often be installed in the same footprint, replacing the inefficient system entirely.

2. Can your racks hold 6-meter sheets like my cantilever rack?
Yes. While standard sheets are 3 meters, we manufacture extended Roll-Out Racks specifically for 6-meter plates. These units feature additional structural supports to ensure the drawer operates smoothly even with such long loads.

3. Is the Roll-Out Rack more expensive than Cantilever?
The initial hardware cost is typically higher than basic cantilever arms. However, when you factor in the 50% floor space savings, reduced material damage, and labor efficiency (1 person vs. 2 people), the Return on Investment (ROI) is usually achieved within 6-12 months.

4. How much weight can a single drawer hold compared to an arm?
A standard cantilever arm might hold 500-1000kg. Our heavy-duty drawers are engineered to hold up to 5,000kg (11,000 lbs) per level. This density allows you to store entire bundles of thick plate in a single drawer.

5. Do I need a forklift to operate the drawers?
No. The drawers are designed to be pulled out manually (crank or hand-pull). You only need a forklift or crane to lift the sheet uit of the drawer. This separates the “accessing” step from the “lifting” step, making it much safer.
