ZAM Coated Steel Cable Ladder Zinc Aluminium Magnesium 450mm Width Coastal Grade

Zinc Aluminium Magnesium Cable Ladder Coastal Grade is the coating system chosen for shoreline and marine industrial sites, where a conventional zinc coating is consumed too quickly by chloride deposition and a stainless route would exceed the project budget.

The ladder is formed from steel with the ZAM zinc aluminium magnesium coating, 450 mm usable width, 100 mm to 150 mm rail height and rung pitch of 225 mm or 300 mm, in 2 m, 2.4 m, 3 m and 6 m lengths. The 18 inch width carries mixed power and control bundles on a single route and still allows a two person lift onto a coastal frame.

ZAM coatings outperform plain galvanizing in chloride environments because the magnesium and aluminium additions change the corrosion product: the film that forms on the surface is more stable and less soluble, so the coating lasts two to three times longer in salt spray testing than a conventional zinc layer of the same mass. Cut edges also self heal through the sacrificial action of the surrounding alloy.

For a coastal route that means fewer inspections, no repainting programme and no rust staining on the concrete or steelwork below. The ladder is complemented by stainless fasteners and isolating washers so the joint does not become the first point of corrosion in a marine atmosphere.

BENDIN produces coated ladder at 3000 m per week for coastal and infrastructure orders, with 180 staff and thirty years of surface treatment experience, exporting 60 to 70 percent of output to ports, utilities and marine contractors. Coating mass, adhesion and colour are checked on every batch against the approved sample.

Minimum order 150 m, 20 to 30 day delivery, 8 to 50 USD per metre, pallet or wooden box packing, terms T/T or Western Union. Tell us the distance from the shoreline, the required service life and the cable load and we will confirm the coating class and the 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: What is the advantage of ZAM over galvanizing?
A: The magnesium and aluminium additions form a more stable, less soluble corrosion product, which extends salt spray life and protects cut edges by sacrificial action.

Q: Is it suitable for a jetty environment?
A: Yes, for C5 coastal and marine atmospheres, with stainless fasteners and isolating washers so the joint does not corrode first.

Q: Which lengths are available?
A: 2000, 2400, 3000 and 6000 mm as standard, cut to order for long runs.

Q: What is the minimum order?
A: Minimum order 150 m, delivery 20 to 30 days, prices from 8 to 50 USD per metre.
