Aplarack / heavy-duty sheet storage
vertical metal plate storage racks
When a customer is storing copper plates or thick metal sheets, one loaded bay can quickly move beyond one ton. That is where ordinary light-duty vertical storage racks start to fail: guide rails twist, casters crush, drawers bind, and the floor becomes the weak point instead of the rack.
Aplarack was built for that kind of load path. For demanding jobs, we can upgrade the frame to a 50×50×3 heavy rectangular tube with full welding. When the floor is uneven or the working load goes above 1 ton, we switch the bottom running system from polyurethane wheels to V-groove steel rail wheels and run them on angle-iron tracks so the drawer still moves smoothly with one person pushing.
Why light-duty vertical racks break down under dense plate loads
The failure mode is usually predictable. Heavy sheet stock creates a concentrated load at the lower rail, then every start-stop movement adds side force. A soft wheel flattens, a thin guide bracket shifts, and the drawer no longer tracks cleanly. That is exactly why the product needs a real structural base, not just a nice-looking outer frame. The overall rack view shows the open-top layout, full-extension drawer access, and the kind of deep bay geometry that lets operators see and reach the load without fighting the structure.
The engineering upgrade path for 1000 kg to 2000 kg drawers
For 1000 kg drawers, the frame, welds, and lower beam must all be treated as a single load system. For 2000 kg drawers, the margin gets even tighter, so the bottom running gear and track interface become critical. Our approach is simple: reinforce the frame with heavy section tubing, keep the drawer path rigid, lock the bay against racking, and let the wheel system absorb movement only in the direction it is designed to move. That is how the rack stays usable after repeated full-load cycles instead of becoming a maintenance problem after a few weeks.
What the base detail and floor-track images prove
The base detail image shows the real proof point: welded nodes, lower support members, and guide hardware sitting under the drawer path where the load actually lives. The floor-track workshop image adds the other half of the story. Once the rack runs on angle-iron tracks with V-groove steel rail wheels, floor resistance drops sharply and the move becomes controlled instead of random. The open top also stays useful for crane access, so heavy plates can still be loaded vertically without forcing operators to drag the load across the bay opening.
What to confirm before you order a heavy-duty rack
- Confirm the maximum drawer load per bay, including whether the working target is 1000 kg or 2000 kg.
- Measure the floor condition and decide whether the rack should run on casters or on V-groove steel rail wheels with angle-iron tracks.
- List the sheet material, thickness range, and bay width so the frame and drawer spacing match the actual plate size.
- Check whether the loading method needs open-top crane access, fork handling, or a mixed workflow.
