Engineering design resources
Start with the task: select a section, define machining details, check a load table or agree the evidence needed for an order. Each resource has its own assumptions and product scope.
Engineering guidance for pultruded FRP specification
Pultruded FRP properties depend on reinforcement direction, resin and section geometry. Select a resource for the decision you need to make, then confirm the material, load case and configuration it covers. The project engineer sets the design and acceptance requirements.
Define a machined part. Use the cutting, drilling and machining guide for cut lengths, holes, slots, notches, datums and edge treatment. Send a drawing revision and identify the dimensions that control fit.
Review a section or connection. Start with the profile calculator for its stated preliminary checks. Hole spacing, edge distance, bearing, fasteners and any adhesive contribution need a connection-specific review. A section calculation does not verify a joint, and generic glass-fiber and carbon-fiber composites do not have interchangeable electrical behavior.
Check product evidence. Match test reports to the offered material and assembly in the evidence library. Use the blank inspection checklist to agree first-article and production records. For grating, read the load-table guide before applying a span or load value.

FRP profile machining: cutting, drilling, slots and notches
Illustrated HTML guide to specifying finished features, datums, tolerances, support and edge treatment. Build a drawing review brief and agree first-article and inspection requirements before ordering machined profiles.

FRP profile design manual (DOC-PF-2026-EN Rev. B)
Reference compiled from the website's data: material references, resin systems, the calculator's screening basis, catalog section properties, uniform-load examples, applications, fabrication and inspection. Read the assumptions and evidence scope alongside every table; a catalog reference is not a report for each listed configuration. Supersedes the withdrawn Rev. A.

Frequently asked questions
Are these design guides free?
Yes. The design guides on this site are free to use. CAD details and editable specification clauses are released to specifiers working on a project that may use F1 Composite material; request them from inquiry@f1composite.com with the project name.
Can your engineers stamp drawings?
We do not stamp drawings, but our team supports your engineer of record with material data, calculation methodology, and review of FRP-specific details. Where a local PE or CEng stamp is required, the stamping engineer is appointed locally, and we supply what they need to check the FRP elements.
How do you keep these guides current with code updates?
Check the date, revision and cited standard editions on the document you use. Ask us to confirm the current reference and its applicability to your project; a published guide does not automatically incorporate later code changes.
Need custom engineering support?
