Overview

A plain pultruded channel is a profile length that can be specified for framing or fabricated into a support. Define the bearing faces, unsupported length, load direction and connection details before selecting a section from the table.

For a slotted strut, include the slot pattern and mating hardware. For cable routes, distinguish a support bracket from the tray or ladder it carries. The cable-system guide sets out the components and documentation needed to review a complete package.

  • Plain C and U sections
  • Specify holes and fittings
  • Color and surface by agreement
  • 6 m lengths or cut to size

Specify the channel formulation and surface finish with the support drawing. Confirm applicable material evidence and connection checks for the proposed section.

Resin routes to review

  • Isophthalic polyesterThe E23-ISO reference uses this resin family. Confirm its suitability for the profile and service conditions.
  • Fire-retardant polyesterState the required fire test and classification, then confirm evidence for the offered formulation and specimen scope.
  • Vinyl esterA candidate for chemical exposure. Provide the chemicals, concentrations, temperatures and exposure duration; specify fire requirements separately.
  • PolyurethaneReview the proposed profile, processing route and mechanical requirements with the supplier.
  • PhenolicA route to evaluate where fire, smoke or toxicity criteria apply. Confirm manufacturability and the relevant test evidence.

A change of resin, reinforcement, pigment or surface finish can change the applicable properties and evidence. Confirm the grade and reports for the offered configuration. Compare resin systems

Questions buyers ask

Is a fiberglass channel the same as a strut channel or cable tray?

This page lists plain pultruded C and U sections. A slotted strut requires defined slot geometry, compatible fittings and support loads. A complete cable tray or ladder also needs side rails, rungs or a base, splices and system documentation. State whether your inquiry covers profile lengths, fabricated supports or a complete cable system so the offered scope can be confirmed.

What colors are available for FRP channels?

State the required color or RAL reference and whether the channel will be used outdoors. Color, surface veil or coating, quantity and delivery are confirmed for the proposed formulation. Agree a sample and surface specification where appearance or UV exposure matters.

Can FRP channels be bolted to dissimilar materials?

Bolted connections can be evaluated using the channel and mating-part drawings. Specify fastener material, hole pattern, washers, bearing surfaces and exposure conditions. Check the complete connection for load transfer and corrosion of its metallic parts; selecting an FRP channel does not remove those checks.
