Cold Drawn Seamless (CDS) tube is a highly specialized steel tubing produced by piercing hot billets and subsequently cold drawing them over a mandrel. This cold working process ensures exceptional dimensional accuracy, excellent surface finish, and significantly enhanced mechanical properties (higher tensile and yield strength).
As a trusted factory, we manufacture seamless precision steel tubes that meet strict global standards including ASTM A519, EN 10305-1, and DIN 2391-2. Our CDS tubes are widely utilized in critical applications such as hydraulic and pneumatic cylinders, automotive parts, heavy machinery, and structural engineering.
