Stop sacrificing your high-purity stainless steel tubes to “storage rash” and forklift damage. In a busy steel service center, every scratch on a polished surface means lost margin. Our Metal profile storage rack systems eliminate the need for dangerous “digging” by allowing 100% overhead crane access. Retrieve specific bar stock or tubing bundles in minutes, not hours.
The Hidden Cost of “Honeycombing” in Steel Service Centers
For operations managers in the metal processing industry—specifically those handling high-value assets like sanitary stainless steel tubes, precision bar stock, or aluminum profiles—storage is not just about space; it’s about surface integrity and retrieval velocity.
Traditional floor stacking or static cantilever racking forces you into a “Last-In, First-Out” (LIFO) nightmare. When a work order comes in for a specific heat number or a specialized alloy buried at the bottom of a stack, your operators are forced to perform “double handling.” They move five bundles to get to one.
This process creates three critical problems for a modern steel service center:
- Surface Damage: Every time a bundle is moved by a forklift, the risk of gouges, crimps, or scratches increases. For high-purity components (like those used in pharma or food & beverage), a scratch often means the material is downgraded to scrap.
- Machine Downtime: Your laser tube cutters and band saws sit idle while the forklift driver navigates the aisles to find stock.
- Safety Risks: Maneuvering 24ft long bundles in narrow aisles is the leading cause of rack impact accidents.
The Solution: Telescopic Capability for Crane-First Logistics
The game-changer for handling long profiles is the Telescopic Cantilever Rack (often called Crank-Out or Roll-Out racking). Unlike static racks, every level of this system functions as an independent drawer.

100% Extension: The Crane Advantage
By rotating a crank (or pressing a button on electric models), the cantilever arm extends 100% out of the rack structure. This exposes the entire length of the tube or profile bundle to the aisle.
Why does this matter? It allows you to switch from forklift retrieval to Overhead Crane (Bridge Crane) retrieval. Using nylon slings or vacuum lifters with a crane is the gold standard for handling sensitive materials like polished stainless steel or thin-wall aluminum. It eliminates the friction and impact associated with steel forklift tines.

Electric Efficiency for Heavy-Duty Applications
For facilities handling solid bar stock or large-diameter thick-wall pipes, the weight per level can exceed 6,000 lbs or even 10,000 lbs. In these scenarios, manual cranking is replaced by electric drive systems.
Our Electric Roll Out Cantilever Rack systems allow operators to stand at a safe distance and control the extension via remote. This is critical for feeding high-volume production lines where speed is essential. The smooth, controlled motion prevents the load from shifting—a common hazard when “jerking” loads with a forklift.

Technical Specifications: Built for the Steel Industry
Our racks are engineered using structural steel components, designed to withstand the rigorous environment of a metal processing plant. We do not use light-gauge roll-formed steel that buckles under impact.
| Feature | Specification | Operational Benefit |
|---|---|---|
| Load Capacity | Up to 11,000 lbs (5,000 kg) per arm level | Handles dense bundles of solid bar stock or heavy-wall structural tubing without deflection. |
| Material Length | Customizable for 20ft, 24ft, or 40ft profiles | Perfect for standard mill lengths, minimizing overhang and sagging. |
| Access Method | 100% Full Extension | Enables direct vertical picking via Overhead Crane (EOT), eliminating side-loading damage. |
| Safety Anchoring | Hilti / Heavy-duty Expansion Bolts | Ensures absolute stability against tipping moment when drawers are fully extended. |
| Surface Protection | Powder Coating / Optional UHMW Liners | Prevents carbon contamination on stainless steel; UHMW liners protect polished surfaces (Ra finish). |
Installation: Anchored for Stability
Because the crank out cantilever rack changes the center of gravity when fully loaded drawers are extended, proper installation is non-negotiable. Our teams focus on precise leveling and heavy-duty floor anchoring using industrial-grade expansion bolts. This ensures that even when a 6,000 lb drawer is fully extended, the unit remains rigid and safe.

Frequently Asked Questions (FAQ)
Q1: Can this rack system accommodate 24-foot stainless steel tubing bundles?
A: Yes. We customize the column spacing and number of arms specifically for your inventory length. For 20ft to 24ft material, we typically use 4 to 5 structural columns to ensure the tubing does not sag, maintaining straightness for your laser feeders.
Q2: We handle “Sanitary” grade tubes with polished finishes. How do you prevent scratches?
A: The primary protection is the 100% extension, which allows crane loading with soft nylon slings instead of steel forks. Additionally, we can install UHMW (Ultra High Molecular Weight Polyethylene) liners on the cantilever arms to provide a non-marring resting surface.
Q3: Does the rack require a guide rail system for forklifts?
A: No. One of the main advantages of our overhead crane accessible racking is that you can eliminate the wide aisles needed for forklift turning radii. You can place racks closer together or near processing equipment, as the primary access is from above.
Q4: What is the maintenance requirement for the crank-out mechanism?
A: Maintenance is minimal. The system uses sealed industrial bearings and a robust gear/rack transmission. We recommend a semi-annual inspection of the floor anchors and a simple lubrication of the drive gears to ensure smooth operation, even in dusty metal fabrication environments.
Q5: Can we retrofit existing static cantilever racks to become telescopic?
A: generally, no. The structural forces on a telescopic rack (torque and overturning moment) are significantly different from a static rack. Our systems use specialized I-beam bases and reinforced columns designed specifically to handle the dynamic loads of extending arms.
