Corrosion Resistant Cable Ladder 6061 T6 Aluminum for Industrial Electrical Systems

Corrosion-Resistant Aluminum Cable Ladder for Industrial Electrical Systems is the long span aluminum route for plants where the cable has to cross a bay or a process area with few available support points, and where a steel ladder would either sag or need intermediate steelwork to hold it.

The ladder is extruded from 6061 T6 or 6063 T5 aluminum in 200 mm to 1200 mm widths with 100 mm to 300 mm rail height, rung pitch of 225 mm or 300 mm and module lengths of 2 m to 5.8 m. The deeper rail section and heat treated alloy are what allow support spans well beyond a standard steel ladder of the same weight.

Corrosion resistance is inherent: the alloy forms a protective oxide film that re seals after a scratch, and there is no zinc or paint layer to renew. In an industrial atmosphere of humidity, sulphur and mild chemical exposure, this removes the inspection and touch up cycle that galvanized routes need, and it eliminates rust staining on the structures below.

For an electrical system the aluminum brings two further benefits. It is non magnetic, so it does not heat through hysteresis when single core cables run in parallel, and it is a conductor, so the ladder itself can form part of the earthing path when the joints are bonded with the supplied kits.

BENDIN extrudes and fabricates this ladder in house with 10000 m weekly capacity, 180 staff and thirty years of cable route engineering, exporting 60 to 70 percent of output to industrial and power contractors. Alloy temper, wall thickness and straightness are checked on every batch, and custom widths and finishes are available.

Minimum order 100 m, delivery on request, 5 to 20 USD per metre, pallet packing, terms T/T, D/A or D/P. Send the route drawing, the cable load and the span between available supports and we will return the rail height, the alloy and a deflection calculation.

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: Which alloy suits a long span?
A: 6061 T6 with a deeper rail, because the heat treated alloy and the section geometry together provide the stiffness needed at 4-6 m support spacing.

Q: Does the ladder need painting?
A: No. The alloy forms its own protective oxide film. Anodizing adds a hard layer for humid or mildly coastal rooms, and powder coating is used for colour coding.

Q: Can it carry single core cables?
A: Yes. Being non magnetic, it avoids hysteresis heating and induced circulating currents when single core cables run in parallel.

Q: What is the minimum order?
A: Minimum order 100 m, prices from 5 to 20 USD per metre, on T/T, D/A or D/P terms.
