Buyer FAQ
Custom carbon fiber tube questions
What dimensions should I provide?
Send the section shape, inside or outside dimensions, wall thickness, length, quantity and critical tolerances. The thin-wall tube specification guide explains how to compare dimensional and construction proposals.
Can weave and finish be customized?
Visible weave and matte or gloss appearance can be reviewed with structural requirements. See the strength and load-direction guide when defining those structural requirements.
Can I request a sample?
Where appropriate, a sample can be reviewed and approved before repeat production.
Specification decisions
Choose the section, then define the interfaces
| Decision | What to define |
|---|---|
| Bore or outside fit | Identify the controlling surface for an insert, clamp or bearing; give the mating dimension and fit requirement. |
| Wall and reinforcement | Separate nominal wall thickness from fibre direction and appearance. Geometry alone does not specify a laminate. |
| Cut ends and secondary work | Mark finished length, cut angle, holes, bonded regions and any cosmetic zones. |
| Acceptance | Agree measurement positions and the drawing revision; request project-specific verification where loads or deflection matter. |
Worked specification example
For a nominal 20 × 18 mm round tube, the calculated wall is 1 mm. An internal insert needs a bore-fit requirement, while an external clamp needs an OD requirement. Neither fit tolerance can be inferred from the nominal dimensions.

Reference & scope
Rock West: roll-wrapped tube range. External supplier documentation illustrates specification practice, not CFW capability limits or an endorsement. This is purchasing preparation guidance, not project-specific engineering approval.
