Storing 6-meter (20ft) metal sheets is the ultimate logistical headache in metal fabrication. If you are floor-stacking these giants, you are killing your laser cutter’s OEE (Overall Equipment Effectiveness). Every time your operator waits for a forklift to dig out a specific thickness of plate from the bottom of a stack, your expensive fiber laser is burning money, not metal. It’s time to stop the “digging” and start managing your raw material flow.
The “Floor Stacking” Trap in Large Format Fabrication
In the heavy fabrication industry—whether you are building truck bodies, structural beams, or architectural facades—handling 6-meter sheets (approx. 20 feet) presents unique challenges that standard pallet racking cannot solve. The sheer length causes material deflection (sagging), and the weight makes handling dangerous.
Most shops default to stacking bundles on the floor. This creates three critical bottlenecks:
- The “Honeycombing” Effect: You need a 6mm mild steel plate, but it’s buried under 10mm and 12mm bundles. Your forklift driver spends 20 minutes shuffling inventory while the laser sits idle.
- Surface Damage: Every time you drag a 6m stainless steel sheet off a stack, you risk scratching the surface. For architectural cladding, that’s an immediate reject.
- Space Waste: Floor stacking consumes massive square footage. In a high-rent industrial zone, using floor space for static storage is a financial loss.
The solution is not just “shelving”; it is a dynamic estantería para chapa designed specifically for extreme lengths and loads.
100% drawer extension allows for overhead crane access without moving other layers.
Why Roll-Out Racks are Essential for 6m Sheets
The core value of a Almacenamiento horizontal de chapas system lies in its drawer mechanism. Unlike cantilever racks where you still need a forklift to pick from the top, a roll-out system allows you to access any sheet, at any level, at any time.
1. Elimination of Material Deflection
When you lift a 6m sheet with a standard forklift, the ends droop. This can cause permanent deformation or make loading onto the laser bed difficult. Our estanterías para chapa de acero support the full length of the material. The drawers are engineered with structural steel beams that prevent sagging, ensuring your material stays flat and ready for precision cutting.
2. Seamless Crane Integration
For 6-meter sheets, overhead cranes (gantry cranes) or jib cranes with vacuum lifters are safer and faster than forklifts. Because our drawers extend 100%, your crane operator can pick a single sheet directly from the rack and transport it to the laser shuttle table. This eliminates the “forklift dance” in narrow aisles.
The Depalletizing Challenge: Solved
One of the biggest hidden costs in handling large format sheets is removing the wooden shipping skids. It is a dangerous, manual process that often leads to pinched fingers or back injuries.
Our system integrates a “Depalletizer” workflow. You simply place the bundle (with wood) into the depalletizer frame, and the system separates the metal from the wood, allowing you to load only the metal into the estante para sábanas desplegables. This keeps your storage density high (no wood taking up space) and reduces fire hazards.

Technical Specifications for 6m Systems
When selecting a system for large format sheets, robustness is non-negotiable. Here are the typical specifications for our heavy-duty line:
| Característica | Especificación |
|---|---|
| Sheet Size Capacity | Up to 6000mm x 2000mm (Approx. 20ft x 6.5ft) |
| Load Capacity Per Drawer | Up to 5,000 kg (11,000 lbs) |
| Extensión del cajón | 100% Full Extension |
| Operation Mode | Electric Crank or Heavy-Duty Forklift Retrieval |
| Densidad vertical | Up to 8-10 levels in a single tower |
From Chaos to Organized Production
Implementing a estantería de chapa system changes the rhythm of your workshop. Instead of a chaotic search for materials, your logistics become a precise operation.
Imagine this workflow: The ERP system releases a job for 6m x 2m x 8mm steel. The operator walks to the rack, cranks open drawer #4, uses the vacuum lifter to pick one sheet, and loads the laser. Time elapsed: 3 minutes. No forklifts blocking the aisle, no scratched material, no safety incidents. This is how modern fabrication competes.
Modular systems allow for massive storage capacity in laser cutting centers.
Frequently Asked Questions (FAQs)
1. Can one person operate a rack loaded with 6-meter steel plates?
Yes. For heavy loads (over 3 tons per drawer), we utilize a geared crank mechanism or electric drive that allows a single operator to open the drawer smoothly without physical strain.
2. How do you prevent the 6m sheets from sliding off when the drawer opens?
Safety is paramount. Our drawers feature rear stoppers and slightly angled designs or anti-slip surfaces to ensure the stack remains stable during movement. The opening speed is controlled to prevent inertia shift.
3. Can I store different lengths (e.g., 3m and 6m) in the same rack?
Yes, but it is not recommended to mix them in the same drawer for balance reasons. However, we can design a modular system where one bay is sized for 3m sheets and the adjacent bay is sized for 6m sheets, sharing the same uprights to save space.
4. Do I need a special forklift to load the rack initially?
For 6m racks, you typically need a forklift with a wide carriage or a spreader bar to load the bundles safely into the drawers (or use the depalletizer method). Once loaded, daily picking is usually done via overhead crane.
5. What is the maximum height for these racks?
We can build towers up to 6 meters high or more, depending on your ceiling clearance and crane hook height. High-bay systems maximize vertical cubic feet that are often wasted in fabrication shops.
