Heavy duty Steel and aluminum sheets rack measuring 3000 x 1500 mm

The 3,000 × 1,500 mm sheet is one of the most common formats in metal fabrication, and it is also one of the most frequently mis-stored. It is large enough that manual edge-lifting becomes a two-person job, but common enough that buyers often treat it as a “standard” size that any rack can handle. In practice, a rack designed for 2,500 × 1,250 mm pallets will not necessarily provide stable, flat support for a 3,000 mm sheet—especially when the material is aluminum, which behaves differently under load than mild steel.

Herochu’s HC-B3015-63 is built specifically around the 3,000 × 1,500 mm format, with six layers as standard and a per-level load rating of 3,000 kg. The frame uses Q235B high-strength steel and a dual-beam structure, and the clear space between levels is set at 120 mm with customization available for thicker stacks or mixed material types.

Why Material Type Changes the Rack Specification

Steel and aluminum do not place the same demands on a storage system. Aluminum is lighter per unit volume, but it is more susceptible to surface marking and localized deformation when supported on narrow contact points. A rack with widely spaced support arms may be adequate for structural steel but can leave pressure marks on brushed aluminum sheet. The support surface and the spacing of the load-bearing elements need to match the material being stored, not just the sheet dimensions.

Herochu approaches this through configurability rather than a one-size-fits-all shelf. The drawer surface, the clear height, and the layer count can be adjusted to the material mix in the building. For a workshop storing both 3,000 × 1,500 mm mild steel and aluminum sheet, the same rack frame can be configured with different drawer surfaces and load ratings per level.

The Retrieval Problem With Mixed Inventory

When steel and aluminum sheets share the same storage area, retrieval discipline becomes a safety issue. OSHA’s general storage requirements state that materials stored in tiers must be stacked, racked, blocked, or otherwise secured to prevent sliding, falling, or collapse. A floor stack of mixed sheets, with different thicknesses and surface finishes, is difficult to secure consistently. Edges catch, layers shift, and the person pulling a sheet has no mechanical control over the load above.

A drawer-based rack changes the access model. Each layer is a separate compartment. The operator extends the drawer for the target material, and the other layers remain stationary. This is not simply a convenience feature—it is a direct response to the stability requirement that unsecured stacks fail to meet.

Herochu’s manual drawer roll-out configuration for the 3,000 × 1,500 mm format is designed around this selective access principle. The drawer carries the stack, the frame carries the drawer, and the operator never reaches into the rack cavity to extract a sheet.

Customization Without Losing Structural Discipline

The risk with customizable storage is that flexibility erodes load discipline. A rack that can be configured “any way you want” can also be configured beyond its structural limits. Herochu’s approach is to treat customization as a specification exercise: the sheet format, the stack weight, the handling equipment, and the access frequency are defined first, and the layer count, clear height, and drawer type follow from those inputs.

For the 3,000 × 1,500 mm format, the practical configuration decisions are usually straightforward. A six-layer rack with 3,000 kg per tier suits most fabrication shops running mixed steel and aluminum inventory. Shops with heavier plate stacks or wider format sheets move to the 5,000 kg models in the same series.

Floor Space and the Hidden Cost of “Temporary” Storage

A 3,000 × 1,500 mm sheet occupies 4.5 square meters of floor space when laid flat. A stack of twenty sheets, including clearance for forklift access, can consume 15 square meters or more per storage position. Many workshops absorb this by designating “temporary” floor zones for incoming material—zones that quickly become permanent and displace production equipment.

A vertical stack in a rated rack replaces that floor footprint with a controlled storage footprint. The same material is held in layers rather than piles, and the aisle space required for access is fixed by the drawer extension rather than by the unpredictable geometry of a floor stack. For operations where floor space is the constraint, the rack is not an additional cost—it is a recovery of space already being consumed by unmanaged inventory.

FAQ

Q: Can one rack store both steel and aluminum sheets measuring 3000 × 1500 mm?
A: Yes, provided the drawer surface and support spacing are configured for the softer material. Herochu customizes the HC-B3015-63 with different drawer surfaces and clear heights so the same frame can serve mixed steel and aluminum inventory without marking or deformation.

Q: What is the standard load rating for a 3000 × 1500 mm sheet metal storage rack?
A: Herochu’s HC-B3015-63 is rated at 3,000 kg per level, with six layers as the standard configuration. Higher ratings are available in the same series for heavier plate stacks.
