Your laser cutter is idling while your operators dig through a pile of 6m stainless steel bundles. Stop the “secondary handling” madness. Store your high-value 304/316L sheets, tubes, and profiles in a system that feeds your production line, not one that chokes it.
The “Hidden Factory” in Metal Fabrication: Why Floor Stacking Kills Margins
In the high-precision world of metal service centers and fabrication shops—like those supplying the pharmaceutical or food & beverage industries—material integrity is everything. You aren’t just storing raw metal; you are storing value.
If you are managing 6-meter lengths of sanitary stainless steel tubing or polished sheets, you know the nightmare of Stapelen op de vloer. It creates a First-In-Last-Out (FILO) bottleneck. To access a specific heat number of material at the bottom of the stack for a rush order, your team has to move three other bundles. This “secondary handling” is where profits evaporate:
- Surface Damage: Every time a forklift spear enters a stack of polished tubes, you risk scratching the Ra 15µin finish, turning a premium product into scrap.
- Machine Downtime: A fiber laser or CNC saw costs hundreds of dollars an hour to operate. If it takes 20 minutes to retrieve the correct 6m sheet or tube bundle, that machine is burning cash, not metal.

Engineering for Access: The Draagarmstelling Voordeel
The solution for 6m sheet and tube storage isn’t just “stronger shelves”; it’s a fundamental change in retrieval mechanics. Our system utilizes a crank-out (or electric roll-out) mechanism that extends the cantilever arm 100% out of the rack structure.
Why Overhead Crane Access Changes the Game
Standard cantilever racks force you to use forklifts in wide aisles (often 4m+). By switching to a telescopic design, you unlock the power of your Overhead Crane (EOT Crane).
The crane can lower straps or a vacuum lifter directly onto the exposed material. This vertical lift path means:
- Zero Aisle Width: Racks can be placed closer together or near walls.
- No Scratches: No forklift tines scraping against adjacent bundles during extraction.
- Speed: A single operator can extend a drawer loaded with 3,000kg of 6m steel, pick the specific sheet or tube, and feed the machine in under 5 minutes.

Custom Rack Design for 6m Loads
Whether you are handling heavy wall structural steel or delicate aluminum profiles, the rack must match the load. We don’t do “one size fits all.” We engineer for the specific deflection limits and weight of your 6-meter stock.
| Functie | Manual (Crank-Out) | Electric (Motorized) |
|---|---|---|
| Load Capacity per Arm/Level | Up to 6,600 lbs (3,000 kg) | Up to 11,000 lbs (5,000 kg)+ |
| Ideal Application | Medium frequency access, Tool & Die, Maintenance | High-volume production feeding, Heavy Plate/Bar |
| Operatie | Ergonomic crank (15kg force to move 3 tons) | Remote control / Push button |
| Material Length | Customizable (Standard 6m / 20ft) | Customizable (Standard 6m / 20ft) |
For operations handling heavy 6m sheets or bar stock, the Manual Crank-Out system uses a high-reduction gear system, allowing a single operator to move tons of steel with minimal effort. This is crucial for maintaining safe storage of heavy pipes and tubes without relying on powered hydraulics for every movement.

Integration with High-Mix Production
Consider a scenario typical for a Steel Service Center like GHWA: You have an order for 50 polished stainless tubes, followed immediately by an order for structural H-beams. In a static rack system, switching between these inventory types is a logistical headache.
With crank out cantilever racks, you can dedicate specific levels to specific SKUs (e.g., 304L vs 316L). The rack becomes a dynamic part of your workflow. The operator identifies the material, hits the remote (for electric versions), and the drawer presents the material to the crane. It transforms your storage area from a static warehouse into an active “vending machine” for your saws and lasers.

Frequently Asked Questions: Metal Service Center Solutions
1. Can these racks handle the deflection of 6m flexible sheets or thin-wall tubes?
Yes. We customize the number of vertical columns and arms based on the material’s rigidity. For flexible 6m sheets or thin tubes, we increase the number of support arms (e.g., using 4 or 5 columns instead of 3) to prevent sagging and ensure the material stays straight.
2. How do you protect polished stainless steel (e.g., Ra 15µin) from rack damage?
We offer optional protective linings for the cantilever arms, such as UHMW (Ultra-High Molecular Weight Polyethylene) strips. This ensures your high-purity stainless tubes rest on a soft, non-marring surface rather than bare structural steel.
3. Does the system require special flooring?
Because these are high-density systems (storing up to 20-30 tons in a small footprint), a standard 6-inch reinforced concrete slab is usually sufficient, but we always perform a load calculation based on your specific floor specs to determine if larger footplates or chemical anchors are needed.
4. Can I store mixed lengths (e.g., 3m and 6m) on the same rack?
Absolutely. The cantilever design has no front columns, so you can place a 3m bundle on the left side and another on the right, or a full 6m bundle across the entire span. Adjustable arm dividers can also be added to separate different SKUs on the same level.
5. What is the aisle width requirement for the crane access?
Zero. Or rather, only enough space for a person to walk. Since you are lifting vertically with an overhead crane, you do not need the 3-4 meter turning radius required for a heavy-duty side-loader forklift. This typically recovers 50% of your floor space.
