GRP Cable Ladder UV Resistant Pultruded 50mm-1200mm Width for Outdoor Sites

GRP Cable Ladder UV Resistant is the outdoor composite route for sites where sunlight is as damaging as chemistry: a glass reinforced plastic ladder formulated with UV stabilizers so the resin surface does not chalk, craze or lose mechanical strength after years of direct exposure.

The ladder is pultruded from E glass in an isophthalic polyester resin with UV absorbers and a fire retardant package, in the standard green finish, with 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 supplied in 3 m or 6 m lengths with stainless fasteners.

Ultraviolet degradation is the main failure mode of unprotected composites outdoors: the resin matrix erodes, glass fibres become exposed and the surface becomes chalky and weak. The stabilizer package and a surface veil in the pultrusion slow that process, so the ladder keeps its colour and its section properties through a long outdoor service life.

The material also delivers the properties that steel cannot: no corrosion, no conductive path, no radio shielding and roughly a quarter of the weight, which makes it practical on roofs, tank farms, solar sites and coastal structures where access for maintenance is difficult and expensive.

BENDIN produces GRP ladder at 10000 m per week with 180 staff and thirty years of composite experience, exporting 60 to 70 percent of output to overseas industrial projects. UV stabilizer content, resin cure and colour consistency are controlled batch by batch, and custom widths and colours are available.

Minimum order 100 m, 25 day delivery, 5 to 15 USD per metre, pallet packing, terms L/C, T/T or Western Union. Send the exposure conditions, the cable load and the span and we will confirm the resin formulation, the rail height and the support arrangement.

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: How is UV resistance achieved?
A: UV absorbers in the resin plus a surface veil protect the matrix from erosion, which is the mechanism that exposes glass and weakens an unprotected composite.

Q: Will the colour fade?
A: Some colour shift is normal outdoors, but the stabilizer package and pigment system keep the change limited and the mechanical properties unaffected.

Q: Is it lighter than steel?
A: Yes, roughly a quarter of the weight of an equivalent galvanized steel ladder, which matters on roofs and structures with limited access for lifting.

Q: What is the minimum order?
A: Minimum order 100 m, delivery 25 days, prices from 5 to 15 USD per metre.
