Select an FRP structural profile by its section, span, loading and connections. Strongrate’s pultruded range includes channels, beams, tubes, angles and sheet for project assemblies. Start with the support layout and exposure conditions so the profile and resin can be reviewed together. Products are manufactured in Nantong, China, and ship from China.
Profile range
- Channels and beams: channels, I-beams and wide-flange beams.
- Tubes: square, rectangular, round and fluted profiles.
- Angles and sections: equal angles, embedded angles and T-shapes.
- Flat profiles: flat strip, sheet and kick plates.
- Decking: pultruded decking panels.

Specify fiberglass beams and connected members
Use the section drawing to distinguish an I-beam, wide-flange beam and channel. Similar outside dimensions do not establish equal stiffness or load capacity, and catalog linear weights are not beam load tables. Match each marked member to the assembly drawing and the following order fields.
| Schedule field | What to identify |
|---|---|
| Section | Profile name and drawing, overall depth, flange width, web and flange thickness, and installed orientation. |
| Member | Unique mark, finished length and quantity; use the same mark on the assembly drawing. |
| Structural review | Span, bearing locations, bracing, load cases and serviceability requirements for the responsible designer. |
| Connections and fabrication | Splices, connection plates, holes and cutouts; specify cutting or drilling separately from the length order. |
| Exposure and finish | Indoor or outdoor service, chemicals, concentrations, temperatures, resin requirement, surface and color. |
| Document control | Drawing and schedule revision, delivery location and required date. |
For walkway and platform framing, coordinate beam positions with grating bearing and panel fastening, panel joints, access openings and handrail attachments. Use the FRP material guide to check material terminology, then attach the member schedule and connection drawings to the project quotation package.
