In the sanitary stainless steel industry, preserving the 20µin Ra surface finish of your electropolished tubes is just as critical as maximizing your facility's footprint. Stop letting wide forklift aisles and clumsy maneuvering eat up your cleanroom space and damage your high-value 316L stock.
For manufacturers of high-purity stainless steel components—like those supplying the pharmaceutical and dairy sectors—storage isn't just about putting things away. It is about maintaining the integrity of ASME BPE compliant materials while navigating the high cost of production floor space. When you are storing 20-foot lengths of electropolished or bright annealed tubing, the traditional static rack calculation fails.
The calculation for a Telescopic Cantilever Rack differs fundamentally because it changes the retrieval method. By switching from forklift access (side-loading) to overhead crane access (top-loading), you eliminate the largest variable in the space equation: the 12-to-14-foot maneuvering aisle.
In a standard layout storing 6-meter stainless bundles, you are forced to dedicate nearly 60% of your floor area to empty air just so a forklift can turn. This is "dead space" that generates no revenue.
By implementing a roll-out cantilever system, you can condense your storage footprint by up to 50%. The math is simple: a crank-out rack requires zero turning radius. You can place racks closer to your CNC sawing centers or laser cutting stations. The aisle only needs to be wide enough for a human operator, not a heavy-duty diesel machine.

Space savings are visible on a blueprint, but the financial impact of scrap reduction is seen on the P&L statement. In the hygienic tubing business, a scratch on the OD (Outer Diameter) or ID (Inner Diameter) of a pharmaceutical-grade tube often renders it useless.
Standard static racks force an operational behavior known as "digging" or "secondary handling." If the specific heat number or alloy grade you need is at the bottom of a stack or blocked by another bundle, the forklift operator must move the blocking material. Every movement is a risk. Steel forks clashing with stainless tubes causes carbon contamination and physical dents.
With an overhead crane accessible racking system, the operator extends the specific drawer 100% out of the rack structure. The crane, equipped with non-marring nylon slings, lifts the bundle vertically. There is no dragging, no digging, and no contact with steel forks. This direct access is the only way to guarantee the surface finish remains within spec.

The goal of a modern Steel Service Center or OEM manufacturer is flow. Bottlenecks occur when high-speed laser cutters wait for raw material. A safe storage of heavy pipes and tubes system placed directly adjacent to the feed table of a machine creates a "Point of Use" storage solution.
Instead of traversing the entire factory to fetch a bundle from the main warehouse, the operator simply cranks out the drawer and loads the machine using a jib crane. Cycle times for material changeovers drop from 20 minutes to under 5 minutes. This efficiency gain allows for smaller batch runs and higher mix flexibility without the penalty of long setup times.

When storing dense bundles of solid bar stock or heavy wall stainless pipes, the structural integrity of the rack is paramount. These are not light-duty shelves; they are heavy engineered structures.
The base must be anchored securely to a slab capable of handling the point loads. Unlike roll-formed steel that can twist under dynamic loads, high-quality rolling racks utilize structural I-beams and heavy-duty bearings to ensure that a fully loaded drawer (up to 6,600 lbs or more) moves smoothly without deflection.

When calculating the ROI of a rolling rack system, consider three factors:
|
Q: How do you prevent carbon contamination on stainless steel tubes stored on these racks? A: We offer UHMW (Ultra High Molecular Weight Polyethylene) liners on the cantilever arms. This creates a non-reactive barrier between the carbon steel rack structure and your stainless steel inventory, preventing iron contamination and scratches. |
|
Q: Can the racks accommodate 20-foot (6-meter) tube lengths without sagging? A: Yes. We configure the number of columns and arm spacing specifically for the length and deflection characteristics of your tubing. For 20-foot lengths, we typically use 4 or 5 arm supports to ensure the tubes remain perfectly straight. |
|
Q: What is the benefit of crane access over forklift access for sanitary tubing? A: Crane access allows for vertical lifting using soft nylon straps. This eliminates the risk of metal forklift tines scraping the polished surface of the tubes and avoids the crushing damage that can occur when forks are wedged between bundles. |
|
Q: How much floor space can I actually save? A: By eliminating the forklift turning aisles (often 12-15 feet wide) and utilizing vertical height more effectively, most facilities see a floor space savings of 40% to 50% compared to static floor stacking or standard cantilever racks. |
|
Q: Are these racks suitable for cleanroom environments? A: Yes. The racks are finished with a high-durability powder coating that is easy to clean and does not flake like standard paint, making them suitable for environments where particulate control is important. |
