Structural GRP

Pultruded GRP profiles for fabrication and structural applications

GRP Pultrusions & Structural Profiles can be used in fabrication and structural-support applications where corrosion resistance and practical handling are important. Pultruded GRP profiles and reinforcement products give designers and contractors an alternative material option for a range of infrastructure and industrial projects.

Captrad can support early conversations around profile geometry, section size, length, connections and the operating environment. This helps establish whether a stocked section or a tailored solution is appropriate before procurement and fabrication are planned.

Typical profile and reinforcement uses

  • Fabricated frames, supports and secondary structures
  • Industrial, utilities and corrosive operating environments
  • Access, guarding and site-infrastructure components
  • Bespoke GRP fabrication and replacement projects

Profile options for fabrication and structural work

Captrad stocks pultruded GRP profiles for fabrication projects that need a lightweight, corrosion-resistant alternative to traditional materials. The standard range includes angle, box, channel and I-beam sections, alongside structural components used in frames, supports, access systems and bespoke composite assemblies.

Profile selection should begin with the required section, length, environment and connection arrangement. Share drawings, preferred profile geometry, quantities and any fabrication details so we can discuss suitable options and practical next steps for the project.

  • Stock angle, box, channel, I-beam and H-beam profile options
  • Flat strips, handrail profiles, tubes, rods and unistrut sections
  • Suitable for fabricated frames, supports and access structures
  • Support for bespoke composite assemblies and replacement work
