Your fiber laser cuts at 2,000 inches per minute, yet your forklift driver spends 15 minutes digging out the right gauge of steel from a floor stack. This disconnect isn’t just annoying; it’s a hidden tax on your shop’s profitability. Integrate a storage solution that matches the tempo of your automation without the six-figure price tag of a fully automated tower.
The “Last Mile” Problem in Metal Fabrication Logistics
In the modern fabrication shop, the bottleneck has shifted. It is no longer the cutting speed of your Amada or Trumpf laser; it is the material handling logistics prima the cut. If you are storing 4×8 or 5×10 sheets on wooden pallets spread across the floor, you are killing your flow.
Il Automated loading compatible sheet steel rack (Dplarack) is engineered to bridge the gap between raw material storage and high-speed processing. Unlike static shelving, this system transforms your inventory into a dynamic, accessible workflow node.
Figure 1: Placed centrally in the warehouse aisle, this drawer-style rack utilizes vertical space to solve the congestion caused by pallets spread on the floor.
Dual-Directional Access: The “Pass-Through” Workflow
The defining feature of our rack is the Bi-directional Access. In a typical JIT (Just-In-Time) layout, the rack serves as a physical firewall between your logistics zone (forklifts) and your production zone (operators).
- Rear Loading (The Dirty Zone): Forklifts load bundles of raw material (Cold Rolled, Galvanized, or Stainless) from the aisle side. The lack of a back panel allows for seamless loading.
- Front Picking (The Clean Zone): The machine operator cranks the drawer out towards the laser cutter or turret punch. Using a vacuum lifter or jib crane, they transfer the single sheet directly to the shuttle table.
This “Tunnel Effect” eliminates the safety risk of forklifts entering the tight spaces around operator stations.

Engineered for Heavy Industry: 5,000 lbs at Your Fingertips
Handling thick gauge plate (e.g., 1/2″ or 1″ mild steel) usually requires a forklift. However, waiting for a forklift driver causes machine downtime. Our Crank-out sheet rack utilizes a rack-and-pinion gearing system with a 1:1.5 ratio. This mechanical advantage allows a single operator to move a drawer loaded with 5,000 lbs (approx. 2.5 tons) of steel using just one hand.
The movement is supported by high-load industrial bearings, ensuring that even under maximum load, the drawer glides rather than grinds. This is critical for reducing operator fatigue and preventing back injuries associated with manual prying of sheets.
Figure 3: The black rotating crank handle connects to a transmission shaft supported by green bearing housings, the core mechanism that allows single-person operation of heavy loads.
Proteggere i vostri beni di valore elevato
For shops fabricating architectural cladding or food-grade equipment, surface quality is non-negotiable. Stacking sheets of #4 Finish Stainless Steel or Aluminum on top of each other invites scratches from debris caught between layers.
Utilizzando un Roll out sheet rack, each bundle acts as an independent SKU. There is no “digging” or “restacking.” You pull the specific drawer, lift the sheet with a vacuum cup, and the surface remains pristine. This significantly reduces scrap rates and rework costs.

Domande frequenti
1. Can this rack be loaded directly by an overhead crane?
Yes. Because the drawers extend 100% out of the rack structure, there is zero overhead obstruction. Your bridge crane or jib crane can drop bundles directly onto the drawer without needing to slide them in manually.
2. We use a vacuum lifter for feeding our laser. Is this compatible?
Absolutely. This is the ideal use case. The drawer rolls out, presenting the sheet to the vacuum lifter. The operator picks the sheet and moves it to the laser bed without ever touching the sharp edges of the metal.
3. What are the flooring requirements for installation?
We recommend a minimum of 6-inch thick reinforced concrete (C30 standard or better). The racks must be anchored to the floor using heavy-duty chemical anchor bolts to handle the cantilever forces when drawers are fully extended.
4. How does this compare to an automated tower system?
An automated tower costs upwards of $200,000 and requires complex software integration. Dplarack provides 80% of the storage density and accessibility benefits at roughly 10% of the cost, with zero software maintenance or electrical requirements.
5. Can we store sensitive materials like copper or polished aluminum?
Yes. We can outfit the drawers with UHMW (plastic) strips or rubber lining to ensure that the bottom sheet of your bundle never touches raw steel, preventing any risk of cross-contamination or scratching.
