Standard FRP profiles are pultruded structural shapes such as channels, I‑beams, and angles. They are used in frameworks and supports where corrosion resistance is required. This page explains the main selection factors for these profiles.
Product Family Overview
Standard profiles are produced in constant cross‑sections, providing predictable mechanical properties. Common shapes include channels, I‑beams, angles, bars, and tubes. Mechanical properties are referenced against EN 13706 grades E23 and E17.
Selection Considerations
- Load direction – pultruded profiles are stronger along the fiber axis.
- Section modulus and moment of inertia – determine bending capacity.
- Resin system – affects chemical resistance and fire behavior.
- Deflection limits – often govern design due to lower modulus than steel.
Frequently Asked Questions
How do I choose between channel, I‑beam, and angle?
The shape depends on the structural function: channels and angles for bracing or secondary framing, I‑beams for primary bending members, and tubes for columns or handrails. The final choice requires structural analysis.
Can I get custom profile sizes?
Custom pultrusion tooling is possible, but standard shapes are more cost‑effective for moderate quantities. Contact our engineering team to evaluate the feasibility of a custom cross‑section.
