In the hygienic stainless steel industry, surface integrity is everything. When you are handling mirror-polished 316L pharmaceutical tubes or precision ASME BPE fittings, a single scratch from a forklift tine isn't just a cosmetic flaw—it ruins the Ra value, creating bacterial traps that render the material scrap. Stop treating your high-value alloys like structural rebar.
The Cost of "Double Handling" in Stainless Service Centers
For a Stainless Steel Service Center or an OEM manufacturing hygienic components, the traditional method of storing long material—floor stacking or static cantilever racking—is a silent profit killer.
Consider the daily reality: You need to pull a bundle of 2-inch OD sanitary tubing located at the bottom of a stack. To get to it, your operator has to move three bundles of 4-inch industrial pipe. This is "Secondary Handling." In the carbon steel world, this wastes time. In the stainless world, this generates friction, scratches, and contamination.
Every time a fork truck maneuvers in a narrow aisle to fish out a bundle, you risk:
* **Surface Damage:** Compromising the mechanical polish or electropolish finish.
* **Cross-Contamination:** Carbon steel dust or contact with forks contaminating high-purity stainless.
* **Inventory Damage:** Bending long, thin-walled tubes due to improper fork spacing.
Safely storing high-value tube bundles without stacking damage.
The Logic: 100% Extension for Overhead Crane Access
The solution lies in changing *how* you access the material. By utilizing a
crank out rack 100% extension drawer system, you eliminate the forklift from the retrieval equation entirely.
Here is the operational shift:
1. **The Drawer Concept:** Each level of the rack is an independent, mobile drawer. Whether manual or electric, the arm extends 100% out into the aisle.
2. **Top-Down Access:** Once the drawer is extended, the material is fully exposed from above. You use your overhead crane (EOT crane) with nylon slings or vacuum lifters to pick the specific bundle you need.
3. **Zero Contact:** The crane lifts straight up. There is no dragging, no friction against other bundles, and no steel-on-steel contact with fork tines.
This system is engineered for the specific needs of high-purity tube handling. You can pick order #1234 (the bottom bundle) without touching the inventory stored above it.
Electric roll-out control allows for smooth, vibration-free access to sensitive materials.
Maximizing the "Clean Room" Footprint
In the pharmaceutical and food equipment manufacturing sectors, floor space—especially in climate-controlled or clean production areas—is incredibly expensive.
Standard racking requires aisles 12 to 14 feet wide to accommodate the turning radius of a heavy-duty forklift carrying 20-foot tube bundles. This is "dead air" that you are paying to heat, cool, and clean.
Because the
crank out rack 100% extension drawer utilizes an overhead crane, you can slash your aisle widths significantly. You only need enough space for the operator to walk and the drawer to extend.
* **Aisle Reduction:** Reduce operational footprint by up to 50%.
* **Vertical Density:** Safely store heavy stainless bars and thick-walled pipes higher up, knowing you don't need a high-reach forklift to retrieve them blindly.
Organizing by Grade and Heat Number
Traceability is non-negotiable in this industry. You cannot mix 304L with 316L, and you certainly cannot lose track of heat numbers for ASME BPE compliance.
The telescopic design allows for precise compartmentalization. By using dividers on the arms, you can separate different ODs, wall thicknesses, or alloy grades on the same level without them touching. This visual clarity reduces picking errors and ensures that the material certificate (MTR) always matches the tube being cut.
Orange dividers ensure strict separation of different alloy grades and diameters.

FAQ: Solutions for Hygienic Manufacturing
Q1: We handle polished sanitary tubing (20µin Ra). Can this rack prevent surface scratching?
Absolutely. The primary cause of scratching is the horizontal friction of sliding tubes out of a pigeonhole or static rack. With our system, you lift vertically using nylon slings. Furthermore, we can line the steel arms with UHMW plastic strips to ensure the stainless steel never touches carbon steel.
Q2: Is the electric model suitable for a clean manufacturing environment?
Yes. The electric drive provides a smooth, controlled motion that eliminates the jerking associated with forklifts. The powder-coated finish is durable and easy to wipe down, generating far less particulate matter than concrete dust churned up by forklift tires.
Q3: How does this help with ASME BPE compliance?
Compliance requires strict traceability and segregation. The drawer system allows you to designate specific levels for specific heat numbers or lots. The improved visibility makes inventory audits faster and prevents the accidental mixing of compliant and non-compliant stock.
Q4: Can we store solid stainless bar stock? It is much heavier than tubing.
Yes. The crank out rack 100% extension drawer is built with structural I-beam and H-beam steel. We can engineer drawers to handle high-density loads like solid bar stock (up to 10,000 lbs per level upon request) without deflection.
Q5: We have a bridge crane but it doesn't cover the entire warehouse. Can we still use this?
The rack must be placed under the crane's coverage area to maximize its value. However, because the system condenses storage space, you can often consolidate all your long inventory into a smaller footprint that fits perfectly under your existing crane rails, freeing up the rest of the warehouse for other operations.
