In high-purity stainless steel manufacturing, every square foot of your facility is calculated against production capacity. When you are storing 20-foot bundles of 316L sanitary tubing or heavy solid bar stock for your CNCs, traditional static racking is a “space thief.” It forces you to maintain wide forklift aisles and risks damaging the critical Ra surface finish of your hygienic components during retrieval. There is a way to reclaim 50% of that floor space while eliminating handling damage.
The “Hidden Cost” of Storing Sanitary Stainless Steel
For manufacturers producing ASME BPE compliant components, valves, or heat exchangers, the storage of raw materials is not just a logistical issue—it is a quality control checkpoint. Standard static cantilever racks present two major problems for this specific sector:
- The Forklift Aisle Tax: To access a 20-foot (6-meter) bundle of tubing with a forklift, you need an aisle width of at least 15 to 20 feet for the vehicle to turn safely. This is “dead air” that you are paying to heat, cool, and insure, but cannot use for production.
- Surface Integrity Risk: Maneuvering long, flexible stainless bundles into a static slot with forklift tines is the primary cause of scratches and gouges. For hygienic tubing where surface roughness (Ra) is critical, a single scratch can turn prime inventory into scrap.
The solution lies in changing the access method from “digging” with a forklift to “picking” with an overhead crane. This is where the Estante telescópica cantilever changes the geometry of your warehouse.

How the Mechanics Create Space
Unlike static racks, a roll-out cantilever system functions like a heavy-duty industrial drawer. The arms are not welded to the column; they sit on a precision-engineered transmission shaft and bearing housing assembly.
By rotating a crank handle, a single operator can extend a fully loaded arm (holding up to 6,000 lbs of solid bar stock) 100% out into the aisle. Because the material comes Fora to the operator, you no longer need to leave space for a forklift chassis to maneuver em. You can stack these racks much closer together, often condensing three rows of static racking into one high-density system.
Figure 2: The gear and rack transmission system allows for 100% extension, making the material fully accessible from above.
The “Crane-First” Workflow: Zero Scratches, Zero Waste
The most significant space-saving factor is verticality. In a stainless steel service center, you often cannot stack static racks very high because forklift visibility decreases at height, increasing the risk of dropping a bundle or damaging the rack.
With a crank out cantilever rack, once the drawer is extended, the material is completely exposed overhead. This allows you to use your shop’s overhead crane or a vacuum lifter to pick the material straight up.
Why this matters for Hygienic Manufacturing:
- No Contact: Vacuum lifters or nylon straps prevent metal-on-metal contact, preserving the polished finish of 304/316L tubes.
- Segurança: No more “fishing” for heavy bars at height. The load is stable and accessible.
- Densidade: You can build the racks up to 5 or 6 levels high (approx. 15-20 feet) and still access the top shelf as easily as the bottom one.

Organizing for Production Speed
Space isn’t just about square footage; it’s about flow. In many facilities, the Estantes acessíveis por guindaste aéreo is placed directly next to the laser tube cutter or band saw. This creates a “Point of Use” storage system.
Instead of transporting materials from a distant warehouse across the plant (risking contamination and damage), the raw stock is stored exactly where it is needed. The rack features adjustable dividers (stop blocks), allowing you to separate different ODs (Outside Diameters) or alloys (e.g., separating 304 from 316L to prevent mix-ups) on the same level.
Figure 4: Adjustable stop blocks ensure different tubing specifications are kept separate and secure during movement.
Conclusion: The ROI of Air Rights
Can a roll-out cantilever rack save space? Yes, typically 50% or more compared to static racking. But for the high-purity stainless industry, the value goes beyond floor space. It protects your inventory from physical damage, eliminates the safety hazards of forklift handling, and streamlines the feeding of your processing machinery.
Perguntas frequentes
| Q: Can we store delicate polished tubing without scratching it? |
| Absolutely. We recommend using protection strips (rubber or UHMW plastic) on the cantilever arms. Combined with overhead crane handling (using nylon straps or vacuum lifters), there is zero metal-to-metal friction during retrieval, preserving the Ra finish. |
| Q: What is the maximum length of stainless bar stock this system can handle? |
| The system is modular. We commonly design 8-column systems to handle standard 20-foot (6-meter) or even 40-foot (12-meter) bundles. The multi-column design prevents the material from sagging or bowing, which is critical for maintaining straightness tolerances. |
| Q: How much weight can a single drawer level hold? |
| Our heavy-duty models are engineered for density. A single arm can support up to 6,600 lbs depending on the configuration. A full level for 20-foot bar stock can easily support 10,000+ lbs, allowing you to store full bundles without breaking them down. |
| Q: Do we need to upgrade our floor foundation? |
| Typically, a standard industrial concrete floor (6 inches reinforced, 3000 psi) is sufficient. However, because the footprint is so small and the load is high, we calculate the PSI load for every project and will advise if footpads need to be enlarged to distribute the weight. |
| Q: Can this rack be placed directly next to a laser cutter? |
| Yes, this is the ideal application. It serves as a “Work-In-Progress” (WIP) station. Operators can hand-crank the drawer, lift the tube with a jib crane, and load the machine in under 2 minutes, minimizing machine downtime. |
