Heavy Duty Steel Cable Ladder ISO 1461 Hot Dip 75mm-250mm Side Height Build

Heavy Duty Cable Ladder Hot-Dip Galvanized carries main power feeders in plants where cable mass is measured in tonnes and the route has to survive two decades of weather, dust and vibration. Every component, rail, rung, weld and cut edge, is immersed in molten zinc after fabrication, so the coating reaches the surfaces that paint can never cover.

Rails are formed from S235JR or Q235B steel to EN 10025, in 2.0 mm to 3.0 mm thickness with 100 mm to 150 mm height, welded to rungs at 225 mm or 300 mm centres in 3 m and 6 m lengths. Zinc thickness is controlled to ISO 1461, typically 65 to 85 micrometres, which is the practical difference between a ten year and a thirty year route in an industrial atmosphere.

The zinc iron alloy layer is harder than the base steel, so it resists the abrasion of dragging heavy armoured cable and the knocks of site handling. Where the coating is scratched, the surrounding zinc protects the exposed steel sacrificially, which is why hot dip galvanizing outperforms paint in tunnels, washdown areas and coastal plants.

Widths run from 100 mm to 900 mm to match feeders from 4 x 95 mm2 up to large parallel runs, and the open rung design keeps ventilation high so cable derating stays mild. Bends, tees, reducers, covers and cantilever arms complete the route and keep the earthing path continuous from end to end.

BENDIN runs its own hot dip line and fabricates 10000 m per week with 180 staff and three decades of galvanizing discipline behind the coating control. We export 60 to 70 percent of production to construction, power and tunnelling contractors, and every batch is checked for coating thickness and adhesion before it is strapped to the pallet.

Minimum order 100 m with 5 to 25 day delivery depending on size, prices from 5 to 50 USD per metre, L/C, D/P, T/T or D/A accepted, and a 10 year guarantee on the galvanized finish. Send the cable schedule and we will size the ladder, the rung pitch and the support spacing for the spans your structure provides.

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.

• Outdoor pipe racks and industrial yards

Q: How long will the galvanized coating last?
A: In a C3-C4 industrial atmosphere a 65-85 um ISO 1461 coating typically gives twenty years or more of maintenance free service, and we offer a ten year guarantee on the finish.

Q: What load can it carry over a 4 m span?
A: Load depends on rail height, thickness and rung pitch. Send the cable schedule and span and we will issue a deflection calculation to the IEC 61537 limit of span over 200.

Q: Is a duplex coating available for coastal sites?
A: Yes. A powder coat over the galvanized layer gives a C5 duplex system for salt laden air, with the zinc still protecting any damaged area.

Q: What is the minimum order and price range?
A: Minimum order is 100 m, with prices from 5 to 50 USD per metre and delivery of 5 to 25 days depending on size.
