Aluminum sheet stock presents specific storage challenges. The metal’s soft surface scratches easily under contact with harder materials or adjacent sheets. Aluminum’s lower density means more sheets can fit per level — but only if the rack is configured with the right clear space and load distribution. Herochu addresses these requirements with a customizable crank operated aluminum sheet rack designed for fabrication shops handling aluminum, stainless, and mixed non-ferrous sheet stock.

Protecting Aluminum Sheet Surfaces

Aluminum’s value drops sharply when surface integrity is compromised. A scratch on a 5052 or 6061 sheet destined for visible architectural or consumer product applications can mean scrap or costly rework. The Herochu crank-out rack solves this by placing each sheet flat on its own drawer, separated from adjacent sheets by the drawer structure itself.

There is no stacking friction. No sheet slides against another during retrieval. Each drawer extends fully, presenting its contents for clean pickup by vacuum lifter, suction cup, or crane hook. For shops handling anodized, polished, or coated aluminum, this independent storage method directly reduces material loss from handling damage.

Crank Operation for Precision Handling

The crank mechanism on the Herochu aluminum sheet rack uses a gear-and-rack drive system that converts the rotational input at the handle into smooth, controlled horizontal drawer extension. This mechanical advantage means that even a fully loaded drawer requires only 20 lbs of torque at the crank handle — 20% less force than a conventional pull-out drawer under the same load.

For aluminum storage, this controlled extension matters. The smooth, steady motion of the crank drive prevents the sudden jerks that can occur with manual pull-out drawers, reducing the risk of sheet shifting during extension. The operator controls the speed of drawer travel, which is particularly important when handling thinner gauge aluminum sheets that can flex during movement.

Customization for Aluminum and Mixed Material Storage

Herochu manufactures each rack to the customer’s material specifications. Clear space between drawers can be reduced for thinner gauges or increased for thicker plate or sheets with protective film. Standard clear space is 120 mm, fully customizable.

Five standard models cover sheet sizes from 2500×1300 mm to 6000×2000 mm, with per-level capacities of 3,000 or 5,000 kg. Aluminum’s lower density means these capacities accommodate more sheets than equivalent steel loads — a 4000×2000 mm aluminum sheet at 3 mm weighs roughly 65 kg, so a 5,000 kg level holds over 75 sheets in a single drawer.

Fabrication Shop Workflow Integration

The crank-out rack’s value extends beyond storage into production workflow. Fabrication shops running laser cutters, waterjet systems, press brakes, and routing equipment benefit from having aluminum sheet positioned at the point of use. A rack placed beside a laser cutting cell allows the operator to crank out a drawer, lift the required sheet with a vacuum lifter, and place it directly on the cutting table — all within a single workflow step.

The full-extension drawer design makes this possible. Once cranked out, the drawer presents its entire contents for access. Overhead cranes, vacuum lifters, and forklifts can all interface with the extended drawer, allowing shops to use whatever lifting equipment they already operate.

Space Utilization and FIFO Control

Vertical stratification in the Herochu rack design converts floor space into storage volume. Six levels of drawers (customizable to four or eight) multiply storage capacity within the same footprint. For fabrication shops where floor space is at a premium, this vertical approach can increase storage density up to four times compared to horizontal stacking.

The drawer-based system also enables first-in, first-out (FIFO) inventory management. Each drawer is individually labeled and accessible, making it straightforward to track material grade, alloy, thickness, and receipt date. Aluminum stock that might otherwise sit unused in a stack — risking oxidation or surface degradation — remains visible and retrievable.

Structural Construction

The main frame is built from Q235B high-strength steel with a dual-beam design that ensures load distribution across each tier. While the stored material is aluminum, the rack structure itself must withstand the cumulative weight of dozens of sheets per level plus the drawer mechanism. The Q235B frame provides the rigidity needed to maintain drawer track alignment and prevent structural deflection over years of operation.

Powered Drawer Option

For high-throughput fabrication environments, Herochu offers a powered drawer option. The electric drive system replaces manual cranking with button-controlled extension and retraction, improving speed and reducing operator effort in demanding retrieval cycles.

Conclusion

A customizable crank operated aluminum sheet rack from Herochu provides the surface protection, operational control, and space efficiency that aluminum and non-ferrous sheet handling requires. The crank drive ensures smooth, operator-controlled drawer extension. The independent drawer storage eliminates sheet-to-sheet contact damage. The vertical design maximizes storage density within limited workshop floor space. For fabrication shops seeking organized, protected, and accessible aluminum sheet storage, Herochu delivers a configurable system built to match their specific material profile and workflow.
