Your fiber laser cutter costs hundreds of dollars per hour to run. So why is it sitting idle while your operator waits for a forklift to dig a specific gauge of stainless steel from the bottom of a stack? The Roll-out metal sheet rack isn’t just storage; it’s a high-efficiency feeding system designed to keep your laser beam on and your downtime near zero.
Stop the “Digging” Cycle: Why Floor Stacking Kills Laser Productivity
In a high-paced metal fabrication shop, the “cherry-picking” problem is the silent killer of profit margins. When you store 4×8 or 5×10 sheets of varying materials—mild steel, aluminum, stainless—in flat stacks on the floor, accessing the bottom sheet requires moving everything on top of it.
This process, often involving a forklift and two operators, can take 15 to 20 minutes. During that time, your laser cutter or turret punch press is idle. Furthermore, every time you double-handle material, you risk **surface scratches** and **edge damage**, particularly on sensitive materials like brushed stainless or aluminum. This leads to rejected parts downstream or expensive rework.

The Logic: 100% Accessibility for Rapid Machine Feeding
The core value of a Roll-out metal sheet rack lies in its drawer mechanism. Unlike static cantilever racks, each level of our rack functions as an independent, movable drawer that can be extended 100%.
Here is how it transforms the workflow at the laser cutting station:
1. **Identification:** The operator locates the required material (e.g., 16-gauge CR steel) visually without moving other stock.
2. **Extraction:** Using the ergonomic handle (or crank for heavy loads), the operator rolls the drawer out.
3. **Loading:** A vacuum lifter or jib crane picks the sheet directly from the drawer and places it onto the laser shuttle table.
4. **Cycle Time:** The entire process takes less than 2 minutes and can be performed by a **single operator**.
This “One-Touch” handling ensures that the material goes from storage to the cutting bed with zero friction, keeping your OEE (Overall Equipment Effectiveness) scores high.

Heavy-Duty Engineering for Metal Fabricators
We understand that a fabrication environment is harsh. Our racks are engineered using structural Q235 steel to withstand the daily abuse of loading heavy plate.
* **Load Capacity:** Standard drawers support up to **5,000 lbs (approx. 2.2 tons)** per level. This is sufficient for dense stacks of 1/2″ or 3/4″ plate.
* **Protection:** The roll-out design prevents sheets from sliding against each other, virtually eliminating surface abrasion—critical for mirror-finish or pre-painted sheets.
* **Space Efficiency:** By utilizing vertical space, you can store up to 50 tons of metal on a footprint of just 70 sq. ft., freeing up valuable floor space for additional welding stations or assembly areas.

ROI Analysis: Floor Stacking vs. Roll-Out Racks
For a shop running high-mix, low-volume production (job shop), the ROI is often realized in less than 6 months purely through labor savings and machine uptime.
| Metrisch | Traditional Floor Stacking | Roll-Out Sheet Rack |
|---|---|---|
| Retrieval Time | 10 – 20 Minutes (requires forklift & digging) | 1 – 2 Minutes (direct access) |
| Operators Required | 2 (one on forklift, one spotting/rigging) | 1 (using vacuum lifter/crane) |
| Materielle Schäden | High (scratches from sliding/restacking) | Near Zero (no contact between sheets) |
| Floor Space Usage | High (sprawling footprint) | Low (vertical density, saves ~60% space) |
| Sicherheitsrisiko | High (toppling stacks, pinch points) | Low (controlled movement, locked drawers) |
Customization for Your Workflow
Every fab shop is different. Whether you are processing standard 4′ x 8′ sheets, 5′ x 10′ oversized plates, or require a Blechregal integrated with an automated loading system, we can configure the height, drawer count, and load capacity to match your specific material mix.

Häufig gestellte Fragen (FAQ)
1. Can this rack handle 5′ x 10′ (60″ x 120″) sheets?
Yes, we offer standard models specifically designed for 5′ x 10′ sheets, as well as 4′ x 8′ and 6′ x 12′ sizes. We can also build custom dimensions for non-standard sheet sizes often used in the automotive or aerospace sectors.
2. What is the maximum weight capacity per drawer?
Our standard heavy-duty crank-out racks are rated for up to 5,000 lbs (approx. 2,268 kg) per drawer. For lighter applications (aluminum or thin gauge steel), we have manual pull-out versions rated for 2,200 lbs.
3. How do I load the rack initially?
You can load the rack using a forklift. For our “Full Forklift” models, the entire drawer acts as a cassette that can be removed and loaded at the receiving dock. For fixed-frame models, you can use a forklift with a depalletizer or an overhead crane to load the extended drawers.
4. Will the drawers slide out on their own?
No. Safety is our priority. Each drawer is equipped with a mechanical locking mechanism that secures the drawer in place when not in use. The drawer only moves when the operator disengages the lock.
5. Can I store skid/palletized material directly in the drawer?
Yes, depending on the model. Our “Full Forklift” style racks are designed to accept the sheet metal along with the wooden skid. However, for maximum density and to prevent wood debris from interfering with laser operations, we recommend depalletizing before storage.
