Customizable Manual Pull Out Aluminum Plate Warehouse Rack

Aluminum plate is one of the least forgiving materials to store. It scratches under a sliding load, dents at the edge, and bends when someone drags a 3-meter sheet off a stack because there is no other way to reach it. Most warehouses solve this with a forklift and a prayer. A customizable manual pull out aluminum plate warehouse rack solves it with geometry: every sheet sits on its own tray, and the tray comes to you.

Herochu builds these units as welded carbon steel frames with roller-track drawers, sized around your material rather than around a catalog page. This guide covers what the design actually does, where the numbers come from, and what to specify before you order.

Where aluminum plate storage usually goes wrong

Two failure patterns repeat in fabrication shops.

The first is flat stacking. Sheets are piled on a floor frame and the only accessible sheet is the top one. To reach a 2 mm panel at the bottom, someone lifts or drags everything above it. That is how surface scratches and bent corners enter a job that was otherwise cut correctly.

The second is a rack that was never sized for the material. A standard shelf unit with 900 mm clear height cannot take a 2000 mm-wide sheet without overhang, and overhang is where edge damage starts. When the rack is too shallow, operators store sheets at an angle, which concentrates load on one edge and deforms the tray over time.

A drawer-based rack removes both problems at the source. Each layer is a dedicated, horizontal support surface, and each drawer travels out of the frame on rollers so the full sheet face is exposed.

How the pull-out drawer works under load

Under each drawer board sits a roller track. That detail decides whether the rack gets used or abandoned. A steel tray running on bare slides needs two people and a pry bar once it carries 800 kg. A tray on rollers moves with one hand at 500–2000 kg per layer, which is the working range Herochu builds to.

In practice the sequence is short:

1. Unlock the drawer at the front latch.
2. Pull the tray out until the limit stop engages.
3. Lift the sheet with a vacuum lifter or crane sling, or slide it straight off the rollers.
4. Push the tray back until the lock clicks.

The limit device is not a convenience feature. It stops a loaded tray from travelling past the frame’s support point, which is the moment when a drawer rack tips or drops a sheet. Herochu fits both a mechanical limit stop and a locking pin per drawer so a tray cannot creep open while a crane is working above it.

What “customizable” covers in real terms

Customization on this product is not a color choice. It changes four variables:

• Layer count. Up to 6 storage layers as standard, with more on request. Layer count sets your total capacity, so it is the first decision.
• Drawer footprint. Maximum feeding size 6000 × 2000 mm, minimum 800 × 800 mm. Anything inside that envelope can be built.
• Load per layer. 2000–4000 kg as a structural range; 3000 kg is the common specification for mixed steel and aluminum plate.
• Positioning. Drawer travel and stop position repeat to ±2.5 mm, which matters when a laser cutter or press brake is fed directly from the rack.

A typical unit stands 3500 × 1700 × 2100 mm. Total height depends on how many layers you specify and the clear height you need above each tray.

Structure, coating and the deformation question

Thick steel welded construction is the reason these racks hold shape after years of loaded drawers. The frame carries load through welded joints into the base, not through bolted brackets that work loose. Q235B-grade structural steel is the usual material, and Herochu runs load simulation on the frame before fabrication.

Coating gets less attention than it deserves. A plate rack lives in an environment with cutting fluid mist, coolant splash and humidity. Herochu applies a double anti-corrosion coating over a zinc base, then a light blue topcoat. The zinc layer handles the moisture; the topcoat handles oil and abrasion from sheets sliding across the frame face.

Specification summary

Working with Herochu

Herochu supplies graphic design and 3D model design support so the rack can be checked against your floor plan before production, plus online technical support, free spare parts, and a 5-year warranty. Return and replacement service covers transport damage. Units ship to building material shops, manufacturing plants and machinery repair shops, and the same frame platform is used in Herochu’s automated laser cutting load/unload storage systems when a manual rack later needs to become part of a line.

If you are weighing a manual rack against a fully automated tower, start with throughput. Under roughly 15 sheet movements per shift, the manual pull-out unit is the cheaper answer and it does not need a PLC to run.
