Frequently Asked Questions

What is the minimum order quantity for carbon fiber products?
We accept small-batch customization. Minimum quantities vary by product type — tubes and plates have lower MOQs, while custom-shaped parts depend on tooling requirements. Contact our sales team for a detailed quote.
What color and finish options are available?
Standard finishes include 3K plain/twill weave, UD unidirectional, and satin, primarily in black. Custom colors and surface coatings — including matte and gloss clear coats — are also available.
What is the typical lead time?
Standard product lead time is 15–25 working days. Custom products are evaluated based on process complexity. Rush service is available — please confirm timelines when requesting a quote.
