Perché le incastellature orizzontali di lamiera metallica battono i sistemi a sbalzo

For decades, the “Cantilever Rack” was the default choice for storing long items. But for sheet metal, it is fundamentally flawed. Placing flexible metal sheets on narrow arms leads to sagging, permanent warping, and dangerous “honeycombing” where inventory becomes trapped. The modern solution is the horizontal sheet metal storage racks system. Unlike cantilever arms that support material at just two or three points, our drawer-based design provides full-length structural support. This treats your expensive inventory like a precision asset, not just lumber, ensuring that every sheet remains perfectly flat and ready for the laser cutter. Parla con un esperto

Eliminating “Material Memory” and Warping

Thin gauge metals (under 3mm) have memory. If you store them on a cantilever rack, gravity causes the sheet to sag between the arms. Over weeks, this sag becomes a permanent “set” or wave in the metal.

When you feed this warped material into a high-speed fiber laser, the uneven surface can cause head collisions, ruining both the part and the nozzle. Our Dplarack system prevents this by providing a solid or grid-lined steel deck for every drawer. The material is supported across 100% of its surface area, neutralizing gravity and guaranteeing that the sheet comes out as flat as it went in.

The “Pick-Any-Sheet” Advantage

Cantilever racks suffer from the “Stacking Problem.” If you need the bundle on the bottom arm, you have to move the items on the floor blocking it. If you need a single sheet from a bundle, you have to climb up or use a forklift to bring the whole bundle down.

Al contrario, il nostro horizontal sheet metal storage racks function like a filing cabinet. Each drawer operates independently. You can crank open the bottom drawer just as easily as the top one, granting immediate access to any SKU without moving other inventory.

Safety: Enclosed vs. Exposed

Forklift accidents involving cantilever racks are common because the arms protrude into the aisle and the load is often unsecured.

Robust bolted connections (H-beams) replace the welded arms of cantilever racks, offering superior fatigue resistance.

We engineer safety into the structure itself: Containment: Material sits interno a steel drawer frame, not balanced on open arms. It cannot slide off if bumped. Aisle Clearance: No protruding arms means safer travel paths for personnel and equipment. Ergonomics: Operators pull material toward them using a geared crank, rather than reaching into the rack or prying sheets apart manually.

Comparison: Cantilever vs. Dplarack

For a quick decision guide, here is how the two systems stack up in a manufacturing environment.

Domande frequenti

1. Why is full support important for sheet metal?
Sheet metal is flexible. Without full support, it drapes over rack arms. This deformation makes it difficult to load onto automated cutting tables and can cause machine faults. Drawers keep the metal dead flat.

2. Can I store bar stock in these drawers too?
Yes. While cantilever is traditional for bar stock, our drawers are excellent for it, especially for shorter lengths (3m or less) or high-value materials that shouldn’t be scratched.

3. Is the Dplarack more expensive than cantilever?
Upfront, yes. It is a machine, not just static steel. However, when you factor in space savings (50% reduction), reduced scrap from damage, and faster picking times, the ROI is typically reached within 12 months.

4. Posso adattare il mio porta-sbalzo esistente?
No. The engineering principles are different. Our system uses dynamic loads (moving drawers) which require a specialized frame and foundation anchoring that standard cantilever uprights cannot support.

5. What is the weight limit compared to cantilever?
Heavy-duty cantilever arms can hold a lot, but so can we. Our drawers are rated up to 5,000 kg each. A single tower can hold 40 tons, matching or exceeding the density of most cantilever setups.
