IEC 61537 FRP Cable Ladder Isophthalic Polyester 50mm-1200mm Width Pultruded

FRP Cable Ladder IEC 61537 is the composite route for projects that specify the international cable ladder standard and a non metallic material at the same time: chemical plants, water works and coastal installations where the design must demonstrate load, deflection and continuity performance against a recognised basis.

The ladder is pultruded from E glass reinforcement in an isophthalic polyester or vinyl ester resin with a fire retardant package, in widths from 50 mm to 1200 mm, rail heights of 50 mm to 200 mm and rung pitch of 225 mm, 300 mm or 450 mm. Modules are 3 m or 6 m with stainless fasteners and a matching fitting family of bends, tees and reducers.

IEC 61537 compliance is demonstrated through load and deflection testing at the specified span, plus the electrical requirements that apply to the system. For a composite ladder the continuity clause is met differently: the material is non conductive, so the route is used where an insulating support is the design intent, and no bonding is provided.

The composite gives a long service life in aggressive environments without a maintenance coating: it resists acids, alkalis, salt solutions and humidity, it does not corrode at cut ends, and it does not need repainting. That removes the recurring cost that dominates steel routes in a chemical plant or a water treatment works.

BENDIN pultrudes FRP ladder at up to 50000 m per week with 180 staff and thirty years of composite manufacturing experience, exporting 60 to 70 percent of output to chemical, water and energy projects worldwide. Resin cure, rung pull out strength and dimensional accuracy are controlled on every batch.

Minimum order 50 m, 10 to 20 working day delivery, prices on request, pallet packing, terms L/C, T/T or Western Union. Send the exposure chemistry, the span and the load and we will confirm the resin system, the rail height and the test documentation required.

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 resin for a chemical plant?
A: Vinyl ester for stronger acids, hypochlorite and solvent traces; isophthalic polyester for dilute acids, salts and general washdown. We confirm against your media list.

Q: How is load performance documented?
A: Through load and deflection testing at the specified span, with the calculation issued for the project and third party testing arranged where required.

Q: Does the route need a maintenance coating?
A: No. The composite does not corrode, so there is no repainting or galvanizing repair programme over its service life.

Q: What is the minimum order?
A: Minimum order 50 m, delivery 10 to 20 working days, pallet packing on L/C, T/T or Western Union terms.
