Fiberglass angle (FRP) profiles

Equal-leg pultruded fiberglass L-profiles for bracing, ledgers and fabricated supports. Compare catalog sections, or submit an unequal-leg drawing for custom review. Define holes and load transfer separately for connection cleats.

Overview

FRP angles can form bracing members, edge supports and ledgers when the section and connections are designed for the application. Choose the leg dimensions and thickness, then define how each leg bears against or attaches to the surrounding structure.

A cut or drilled angle used as a cleat needs its own fabrication drawing and connection check. For unequal legs or an unlisted section, send the required geometry and quantity so tooling and manufacture can be reviewed.

  • Equal-leg catalog sections
  • Unequal legs: custom review
  • Specify cleat and hole details
  • 6 m lengths or cut to size

Properties

Material reference · E23-ISO

Published reference values for the general-purpose isophthalic polyester laminate. Match the section, formulation and supporting documents before selecting design values for an order.

The listed moduli, tensile and flexural strengths, and pin-bearing strength use EN 13706-3 E23 minimums. ILSS, density and glass content are the published E23-ISO material references. These values and method names do not constitute a test report for the selected profile. Full property table and test methods

For a connection angle, confirm the proposed laminate and assess the fasteners, holes, bearing surfaces and load direction together. Nominal section properties alone do not establish cleat capacity.

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

Are unequal-leg FRP angles available?

The table lists catalog sections. An unequal-leg or unlisted angle can be submitted for custom pultrusion review with leg dimensions, thickness, radii, tolerances, material and expected quantity. Tooling availability, feasibility and sample requirements are confirmed against that drawing before a production offer.

Does a catalog angle qualify as a structural connection cleat?

A catalog angle defines a section, while a cleat also needs cut length, holes, fasteners, bearing surfaces and a load case. The connection review must cover the actual load path, including local bearing, pull-through and loads applied away from the section centre. Include the mating parts and required acceptance basis with your inquiry.

Can FRP angles be used in concrete-embedded connections?

An embedded detail requires assessment of anchorage, concrete bearing, movement and the proposed laminate's compatibility with the exposure. Send the concrete and angle geometry, load directions and environmental conditions. Use material data and connection evidence relevant to that detail instead of assuming that a standard angle or resin name qualifies the assembly.
