Stop Compromising Your Sanitary Finish.
For manufacturers of high-purity stainless steel tubes and hygienic components, a scratch isn't just a defect—it's a scrapped product. Conventional static racks force you to drag polished bundles across rough surfaces. Our jam-free, retractable arms eliminate friction, ensuring your 10 Ra finishes remain pristine from storage to the saw.
In the precision metal industry—specifically for those supplying the pharmaceutical, dairy, and semiconductor sectors—inventory quality is paramount. When you are dealing with electropolished stainless steel tubes (like 316L) or high-grade aluminum profiles, the standard "forklift and push" method is a liability.
Traditional fixed cantilever racks create a "dead zone" for inventory. To access a bundle of 2-inch OD tubes stored in the back, your forklift operator has to shuffle the front bundles. This secondary handling is where 90% of damage occurs. Fork tips graze the polished surfaces, or bundles slide against each other, creating micro-scratches that violate ASME BPE surface finish standards. Furthermore, if the retrieval arms jam or jerk during extraction, the sudden movement causes round stock to roll and collide, further compromising the surface integrity.
Traditional floor stacking and static racking restrict crane access, leading to dangerous manual rigging and product damage.
The solution lies in changing the mechanics of retrieval. Our Telescopic Cantilever Rack systems are engineered to function as industrial drawers for your heavy bar stock and piping. The core differentiator is the transmission system designed for smooth, non-jerky extension, even under full load (up to 5 tons per arm).
Unlike cheap knock-offs that rely on simple friction slides which bind under heavy weight, our system utilizes high-precision bearings and a gear-rack transmission. This ensures that whether you are using a manual crank or an electric drive, the motion is fluid and linear. This "jam-free" design is critical for safety; it prevents the "stick-slip" phenomenon where a stuck drawer suddenly releases, potentially destabilizing the load.
Precision bearing assemblies ensure the crank mechanism operates smoothly without jamming, even under heavy loads.
By allowing the cantilever arms to extend 100% out of the rack structure, we completely alter the material handling workflow. You no longer need to navigate a forklift down narrow aisles. Instead, you can utilize your shop's overhead crane (bridge crane) to perform vertical lifts.
For a Steel Service Center handling 20-foot lengths of tubing, this is a game-changer:
Consider a facility like GHWA, processing high-volume stainless steel components. The bottleneck often isn't the cutting speed of the laser or saw—it's the "feed" time. Waiting 15 minutes for a forklift driver to dig out the correct diameter tube kills efficiency.
By placing electric roll-out cantilever racks directly adjacent to the cutting station, operators can retrieve raw materials in under 3 minutes. The electric drive option allows the operator to extend the rack with a remote control while simultaneously positioning the vacuum lifter or crane, creating a seamless "Pit Stop" style workflow.
Designed for the rigors of heavy industrial environments, our racks are built from structural steel, not cold-rolled sheet metal. The base is anchored securely to your concrete slab to handle the moment forces when arms are fully extended.

Secure floor anchoring is essential for the stability of high-density storage systems.
Q1: Can we store polished stainless steel tubes directly on the steel arms?
While the arms are smooth powder-coated steel, for high-purity (Ra < 20µin) or electropolished tubes, we strongly recommend our optional UHMW (plastic) liners or rubber strips on the arms to ensure absolutely zero metal-to-metal contact.
Q2: How much force is required to crank out a fully loaded arm (e.g., 6,000 lbs)?
Our gear reduction ratio is designed for ergonomics. Even with a full 6,000 lb load of solid bar stock, a single operator can extend the arm with approximately 20-30 lbs of crank force. It is designed to be "jam-free" and smooth.
Q3: We have limited aisle space. How much space can this save compared to standard cantilever racks?
Because you load and unload from the top using a crane, you can eliminate the 12-15 foot wide aisles required for heavy-duty forklifts to turn. You can typically reduce your footprint by 50% or double your storage capacity in the same footprint.
Q4: Is the electric version necessary for a steel service center?
If your pick frequency is high (e.g., feeding a laser cutter every 10-15 minutes), the electric roll-out cantilever is recommended to reduce operator fatigue and speed up cycle times. For long-term storage or lower frequency picks, the manual crank is cost-effective.
Q5: Can these racks be installed on standard warehouse concrete floors?
Yes, but the concrete must meet specific psi and thickness requirements (typically minimum 6 inches of 3000 psi reinforced concrete) due to the high point loads. Our engineering team provides specific load data for your facility manager to verify.
