Your saw cutter is idle. Your operator is spending 20 minutes digging through stacks of bar stock, moving three bundles just to get to the one they need. This isn't just inefficient; it's a direct drain on your shop's profitability. Stop the material shuffle and start feeding your machines directly.

The Real Cost of Your Current Bar and Tube Storage System

For any steel service center or metal fabrication shop, the space between your bulk storage and your processing machines (like saw cutters, plasma tables, or CNCs) is a critical bottleneck. The traditional methods of storing long materials—either floor stacking or using standard fixed cantilever racks—create a "hidden factory" of waste that actively undermines your productivity and safety.

The Daily Grind of "Secondary Handling"

With conventional storage, materials are buried. To access a specific bundle of steel tubing at the bottom or back, your crew is forced into a time-consuming process of "secondary handling." This involves moving multiple, heavy bundles out of the way first. This isn't value-added work; it's pure waste. Each cycle can take 15-25 minutes, during which your expensive machinery sits idle, waiting for material. This directly translates to lost production capacity and missed deadlines.

The Inefficiency of Forklift Aisles

Standard cantilever racks demand wide aisles, typically 10-13 feet, to accommodate forklift movement and turning radius. This space is a "space liability"—it stores nothing and generates no revenue, yet you pay for every square foot. In a crowded facility where floor space is at a premium, this wasted area could be used for a new machine or a value-added processing station.

How a Crank Out Cantilever Rack Redefines Your Workflow

The solution isn't just a better rack; it's a fundamental shift in how you access and supply materials. A crank out cantilever rack, also known as a roll-out system, transforms static storage into a dynamic, high-density supply station right at the point of use.

100% Extension: End the Material Shuffle for Good

The core innovation is that every storage level acts like a heavy-duty drawer. Using a simple hand crank, a single operator can smoothly extend a fully loaded level—weighing up to 5 tons—completely out into the open. The target material is now fully exposed, with no other bundles obstructing access. This simple, reliable mechanism eliminates secondary handling entirely.

Overhead Crane Access: Reclaim 50% of Your Floor Space

Because the extended drawer presents the material in an open aisle, the primary handling tool shifts from a ground-based forklift to an overhead crane (EOT crane). Your crane can now access any bundle from directly above using slings or vacuum lifters. This is a game-changer. By eliminating the need for wide forklift aisles, you can place racks much closer together, instantly reclaiming up to 50% of the floor space previously dedicated to storage. This recovered space can be used to expand production, not just storage.

Feature Direct Benefit for Your Shop
100% Fully Extendable Arms Eliminates Secondary Handling: Access any specific bundle of bar stock or tubing in under 3 minutes. Feeds your saw cutters and CNC machines faster, dramatically increasing their uptime and overall throughput.
Overhead Crane Accessibility Saves up to 50% Floor Space: Frees up valuable square footage by eliminating wide forklift aisles. This allows you to add another production machine without a costly facility expansion.
Independent, Selective Levels Prevents Material Damage: No more dragging bundles over each other. Protects the surface finish of sensitive materials like stainless steel or aluminum profiles, reducing scrap costs. Enables true First-In, First-Out (FIFO) inventory management.
Heavy-Duty Steel Construction (H-Beam Base) Ensures Operational Safety: Drastically reduces forklift traffic in the storage area, a major source of accidents. Eliminates the risk of unstable material stacks collapsing during retrieval. The entire system is anchored securely to the floor.

Engineered for Your Specific Inventory and Throughput

Whether you're a high-volume steel distributor or a specialty fabrication shop, the system is tailored to your exact needs.

Manual Crank-Out System: Simplicity and Reliability

The hand-crank system is a marvel of mechanical advantage. A single person can effortlessly roll out a level loaded with thousands of pounds of steel. It's an ideal, cost-effective solution for storage bays accessed a few times per shift, providing a massive upgrade in safety and efficiency without the complexity of powered systems.

Electric Roll-Out System: Maximum Efficiency for High-Frequency Ops

For high-throughput environments where material is being moved constantly, the electric-powered overhead crane accessible racking is the ultimate solution. With the push of a button on a handheld remote, the operator can select and extend the desired level. This maximizes speed and minimizes operator effort, making it perfect for feeding your most critical and demanding production lines.

Built to Withstand the Industrial Environment

These racks are not office furniture; they are heavy-duty industrial equipment designed for decades of service. The foundation is built from structural H-beam steel, providing a rock-solid base. All components are protected by a durable powder-coat finish that resists chipping, scratching, and corrosion. The modular, bolted construction allows for a streamlined installation process, often pre-assembled in large sections to minimize disruption to your operations. Each unit is securely anchored to your concrete floor, ensuring absolute stability and safety.

Frequently Asked Questions

1. How does this system handle long materials, like 20-foot or 40-foot lengths of structural steel?

The system is modular. To accommodate longer materials, we simply add more vertical tower supports. For a 20-foot load, a three-tower configuration is common. This ensures the material is fully supported along its length, preventing sagging or bowing, and distributes the load evenly across the structure.

2. What are the concrete floor requirements for a fully loaded, high-capacity rack?

This is a critical consideration. Because the system creates very high-density storage, the point load on the floor can be substantial. We will provide detailed load calculations based on your specific rack configuration (number of levels, capacity per level, etc.). Your foundation must be a reinforced concrete slab of adequate thickness and strength (e.g., typically at least 6 inches and 3,000 PSI) to safely support the system and its anchor bolts.

3. Can the rack be customized to protect delicate materials like polished stainless steel or aluminum extrusions from scratches?

Absolutely. We can equip the steel arms with protective UHMW (Ultra-High-Molecular-Weight) plastic liners or other non-marring surfaces. Combined with the use of nylon slings on your overhead crane, this creates a "no-touch" handling process that virtually eliminates the risk of scratches and surface damage, significantly reducing your scrap rate for high-value materials.

4. What is the typical ROI when placing a crank out rack next to a CNC saw or plasma cutter?

The ROI is typically very rapid, often under 18 months. The calculation is straightforward: (Time saved per material change) x (Number of changes per day) x (Your machine's hourly operating cost). If your $200/hour machine waits an extra 15 minutes for material 10 times a day, that's 150 minutes of lost production, costing you $500 daily. By reducing that wait time to 3 minutes, you reclaim over $400 in productive capacity every single day.

5. We use a variety of material sizes. How does the rack accommodate this?

The system is highly adaptable. We offer optional, movable divider pins that can be placed along the length of the arms. This allows you to create smaller, dedicated compartments on a single level. You can store short remnants, smaller bundles, and full-length stock on the same drawer without them mixing, keeping your inventory perfectly organized and accessible.
