Marine Grade Cable Ladder Salt Spray Resistant 200mm-700mm Width for Offshore Use

Marine Grade Cable Ladder Salt Spray Resistant is built for the splash zone reality of ports, shipyards, jetties and offshore structures, where salt deposition, constant humidity and galvanic exposure attack cable support systems faster than any inland environment.

The ladder is produced in 316L stainless steel as the marine default, with aluminum 6063 and hot dip galvanized steel alternatives where weight or budget governs. Widths run from 200 mm to 700 mm, rail heights 100 mm to 150 mm, rung pitch 225 mm or 300 mm, in 2 m and 3 m modules with stainless fasteners throughout.

Type 316L is the grade that survives chlorides: the molybdenum addition raises resistance to pitting and crevice corrosion, and because the alloy is homogeneous there is no coating to chip, scratch or replace. In a salt spray test to ISO 9227 the section shows no red rust, while galvanized steel in the same exposure would show white rust and then base metal attack at cut edges.

For weight sensitive structures the aluminum version offers a naturally passivating oxide film and non magnetic behaviour, and anodizing adds a hard barrier for splash zones. Both materials are compatible with the same fitting family so a route can mix stainless in the wet zone and aluminum in the dry zone.

BENDIN produces marine grade ladder at 7000 m per working day with 180 staff, thirty years of cable route experience and 60 to 70 percent of output exported to shipyards, ports and offshore contractors. Material certificates are traceable to the heat number, and each order is checked for weld quality, straightness and fastener grade.

Minimum order 600 pcs, 25 working day delivery, 10 to 30 USD per piece, pallet packing, terms L/C, D/P or T/T. Tell us the exposure zone, the cable load and the structure type and we will confirm grade, fastener specification and support spacing.

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.

Q: Why 316L rather than 304 for marine air?
A: Molybdenum in 316L raises resistance to pitting and crevice corrosion in chlorides, which is the failure mode that shortens 304 life in salt spray zones.

Q: Are the fasteners the same grade?
A: Yes. A4-70 stainless fasteners are used so no galvanic couple forms between the ladder and the bolts, which is a common source of early corrosion.

Q: Can the route mix materials?
A: Yes. Stainless in the splash zone and aluminum in the dry zone is a common arrangement, and both use the same fitting family.

Q: What is the minimum order?
A: Minimum order 600 pcs, delivery 25 working days, prices from 10 to 30 USD per piece.
