Stainless Steel Cable Ladder Pickled Passivated 316L Grade 150mm-900mm Width

Stainless Steel Cable Ladder Corrosion Resistant is built for cable routes where aggressive chemistry, frequent washdown or salt laden air would destroy ordinary galvanized steel within a few seasons. The open rung form carries power, control and instrumentation cable while letting heat escape freely, so every circuit stays visible, ventilated and serviceable without dismantling the run.

Side rails are cold roll formed from 304 or 316L strip to ASTM A240 and EN 10088-2, then welded or riveted to round or square tube rungs at 225 mm or 300 mm centres. After fabrication the complete assembly is pickled and passivated, which restores the chromium oxide film on welds and cut edges and removes free iron picked up during handling and storage.

Because there is no zinc layer to deplete, the corrosion barrier is the full section thickness: a 2.0 mm rail is still 2.0 mm after a decade in a chloride atmosphere, so mechanical capacity does not decay with the coating. The alloy is non combustible, keeps useful strength beyond 800 degrees C and produces no toxic smoke, which matters where fire integrity and smoke control form part of the specification.

Grade selection drives service life. Type 304 handles food, beverage, pharmaceutical and general indoor washdown duty; type 316L adds molybdenum for chlorides and is the correct choice for desalination plants, coastal substations, pulp mills, fertiliser lines and offshore modules. Both grades are available with matching bends, tees, reducers and support brackets so the system stays electrically continuous for earthing.

BENDIN manufactures this ladder in its own 180 staff fabrication plant, with laser cutting, robotic welding and an in house passivation line under one roof, which is why we hold 25 working day lead times on 100 m orders while exporting 60 to 70 percent of output to more than 1000 industrial buyers. Three decades of cable management experience sit behind every drawing review, and each lot ships with mill certificates traceable to the heat number.

Ordering is straightforward: minimum 100 m, widths from 50 mm to 1200 mm, lengths of 2 m, 3 m or 6 m, pallet or crate packing, and L/C, T/T or Western Union terms. Send the cable schedule and route plan and our engineers will return a sized ladder with support spacing, load deflection reports and a complete bill of fittings.

BENDIN holds ISO 9001 quality certification and issues CE Declarations of Conformity. The standards above state the design and test basis of this product; third party test reports or national approvals are supplied on request and are not implied unless confirmed in the contract.

Dimensions, rung spacing and surface treatment are produced to project drawings. Load and deflection calculations are issued for spans above 3 m.

• Chemical, fertiliser and chlor alkali plants
• Food, beverage and pharmaceutical washdown areas
• Desalination plants and coastal substations
• Wastewater treatment and pumping stations
• Offshore modules, shipyards and port terminals

Q: Which grade should I choose, 304 or 316L?
A: Choose 304 for indoor washdown and general process areas. Choose 316L where chlorides, salt spray or desalination brine are present, because the molybdenum addition resists pitting and crevice corrosion.

Q: Is the ladder supplied with mill certificates?
A: Yes. Every lot ships with mill test certificates traceable to the heat number, plus a coating and dimensional record. Third party inspection can be arranged before shipment.

Q: Can you produce non standard widths and rung spacing?
A: Widths from 50 mm to 1200 mm and rung pitch of 225, 300 or 450 mm are produced to drawing, with matching bends, tees, reducers and brackets from the same material.

Q: What is the minimum order and lead time?
A: Minimum order is 100 m with a 25 working day lead time. Pallet or crate packing is standard, and L/C, T/T and Western Union terms are accepted.
