Import Carbon Fiber Tubes — Buy in Bulk from Supplier in China

General Seasons Composite Co., Ltd supplies carbon fiber tubes manufactured in Guangdong, China. The tubes are offered in diameters from 6 mm up to 100 mm and achieve tensile strengths exceeding 500 MPa, while their density is roughly 30 % of that of aluminium, giving a weight reduction of about 70 %. The composite structure uses high‑grade Taiwanese or Japanese epoxy resin and carbon yarn, providing consistent mechanical performance.

In the carbon‑fiber industry, wall thickness typically ranges from 1 mm to 3 mm for the sizes mentioned, and a standard resin system of epoxy with a glass transition temperature above 180 °C is common. Typical surface finish is smooth with a tolerance on outer diameter of ±0.2 mm, and ellipticity is kept within ±0.5 % to ensure dimensional stability. The tubes are supplied in bundles of up to 20 pieces, each wrapped in anti‑static film to protect against moisture ingress. These specifications align with the requirements of aerospace and high‑performance automotive manufacturers.

The product is suited for aerospace wing spars, automotive chassis members, and high‑end sporting equipment where stiffness‑to‑weight ratio is critical. Buyers can request a minimum order quantity that matches their production schedule, and trade can be arranged on FOB or CIF terms with payment via L/C or T/T. Prior to shipment, the supplier can provide test certificates for tensile strength and dimensional inspection upon request.

General Seasons Composite Co., Ltd is based at 5f, No.9, Changfeng Industry Zone, Dongk Shenzhen, Guangdong 518106, China. The company is classified as an imported‑tier supplier and holds a harbour trust tier, indicating that it has been verified for basic commercial credibility on the platform. Its listed response metrics show a response rate of 0 % and no recorded average response time.

The firm lists carbon‑fiber composites as its core product line and offers custom tube dimensions to meet client specifications. While the public profile does not disclose production capacity, certifications, or client references, interested buyers can request detailed factory information and quality management documentation directly from the company.
