Heavy duty motorized roll out cantilever rack for industrial steel storage

In a high-volume steel service center, your inventory is your bank account. Yet, storing 20-foot polished stainless steel tubes or heavy solid bars on floor stacks is a recipe for surface damage and “buried” stock. Standard static racks force your forklifts into dangerous, narrow aisles, risking collisions with both your racking and your high-value inventory. It’s time to switch to a system built for the harsh reality of metal fabrication.

The Hidden Cost of “Good Enough” Storage in Metal Fabrication

For a metal fabrication shop or a steel distributor dealing in high-purity stainless steel (like ASME BPE standard tubes), the warehouse floor is a battlefield. You are dealing with heavy loads, abrasive metal dust, and the constant movement of machinery. In this environment, the traditional method of floor stacking or using static cantilever racks creates a bottleneck that bleeds profit.

The primary issue isn’t just space; it’s surface integrity en accessibility. When you store bundles of 316L stainless tubing with a 20 µin Ra finish on a static rack, retrieving the bottom bundle requires a forklift to move everything above it. This “secondary handling” is where scratches, dents, and contamination happen. In the hygienic processing world, a scratched tube isn’t just a defect; it’s scrap.

Engineering for the “Grind”: Why Durability Matters

When we talk about Duurzame racks voor zware industriele omgevingen, we aren’t talking about light-duty shelving. We are talking about structural steel systems designed to withstand the impact of daily industrial operations.

Unlike roll-formed steel that can buckle under side-impacts, our systems utilize structural H-beam bases (200x200mm) and thick-walled rectangular tube columns. This rigidity is essential. When a 5-ton bundle of solid bar stock is loaded, the rack must maintain zero deflection to ensure the telescopic arms function smoothly.

Sealed for Reliability

In a cutting or grinding workshop, metal particulate is everywhere. A standard sliding mechanism would jam within months. Our telescoopgiek systems utilize heavy-duty, sealed industrial bearings and a protected gear-and-rack transmission. This ensures that even after years of exposure to shop floor dust, a single operator can still crank out a fully loaded arm with minimal effort.

The Crane Advantage: Eliminating Forklift Damage

The most significant shift in modern steel warehousing is the move from forklift-dependent retrieval to overhead crane retrieval. Forklifts require wide aisles (often 12-14 feet) and rely on the driver’s visibility, which is often blocked by the load itself. This is the leading cause of “rack rash” and damage to long goods.

Onze Draagarmstelling features arms that extend 100% out into the aisle. This creates a clear vertical path for your overhead crane or vacuum lifter. You can pick up a specific bundle of polished tubes using soft nylon slings without ever touching adjacent bundles. This “pick-and-place” precision creates a zero-damage handling process essential for high-value alloys.

Recovering the “Hidden Factory” Space

In the metal service industry, square footage is a fixed cost, but volume is variable. Traditional static racks waste up to 60% of your floor space on forklift aisles. By switching to overhead crane accessible racking, you can slash aisle widths significantly. Since the crane operates from above, you only need enough space for the operator to walk, not for a forklift to turn.

We typically see clients condense three bays of static racking into one high-density roll-out system. This recovered floor space allows you to install additional processing equipment—like a new laser cutter or band saw—directly next to the storage, creating a lean “Point of Use” workflow.

Technical Specifications & ROI Comparison

To understand the tangible impact on your operations, compare the standard storage method against our industrial roll-out solution.

Functie Standard Static Cantilever Roll-Out / Telescopic Rack
Retrieval Method Forklift (Requires wide aisles) Overhead Crane / Vacuum Lifter
Picking Selectivity Poor (Must move top items to get bottom) 100% (Direct access to any level)
Material Damage Risk High (Fork impact, sliding friction) Near Zero (Vertical lift, no contact)
Single Arm Capacity Variable Up to 6,600 lbs (3,000 kg) per level
Aisle Width Required 12ft – 16ft Minimal (Operator walkway only)

Installation and Anchoring

Safety starts at the foundation. Because these racks handle dynamic loads (the shifting center of gravity when arms are extended), proper installation is non-negotiable. Our teams use heavy-duty expansion bolts to anchor the H-beam base deep into your concrete slab, ensuring stability even when fully loaded drawers are extended.

Veelgestelde vragen

1. Can these racks handle 20-foot (6 meter) stainless steel tube bundles without sagging?

Absolutely. We customize the number of columns and arm spacing based on the deflection properties of your material. For flexible materials like small-diameter tubing or plastic profiles, we add more support arms to prevent sagging. For rigid 20-foot steel bundles, a 4-column or 5-column setup is standard, ensuring the material remains perfectly straight.

2. What are the floor requirements for installing these heavy-duty racks?

Due to the high density of the load (often exceeding 20 tons per unit), a reinforced concrete floor is required. Typically, we look for a minimum slab thickness of 6 to 8 inches (150-200mm) with a specific psi rating. Our engineering team will review your facility’s floor specs before installation to ensure safety.

3. We use a vacuum lifter for our polished sheets and tubes. Is this compatible?

Yes, this is the ideal use case. Because the arms extend 100% clear of the rack structure, there are no overhead obstructions. Your vacuum lifter can descend directly onto the material stack without the risk of the lifter’s frame hitting the rack columns, which is a common problem with standard shelving.

4. How much force is required to crank out a fully loaded arm?

Despite holding loads of up to 6,600 lbs per level, our gear reduction system allows a single operator to crank the arm out with approximately 15-20 lbs of force. It is designed to be ergonomic and does not require heavy physical exertion. For even higher frequency operations, we offer motorized versions.

5. Can we store short cut-offs and long bars on the same rack?

Yes. We can outfit specific levels with steel trays, baskets, or closely spaced bridge arms to accommodate short “drops” or cut-offs. This prevents the clutter of short pieces piling up on the floor and keeps your inventory organized for the next job.
