The item is a precision seamless steel tube made from carbon steel grades 20# or 45# (or equivalent). The supplier provides outer diameters from 6 mm to 60 mm and wall thicknesses between 1 mm and 12 mm, with dimensions that can be customised to meet specific engineering drawings. Typical surface finishes include hot‑dip galvanised and black oxide, and the tubes are shipped in bundled or wooden‑crated packs suitable for container loading.
These tubes meet ASTM A106 and GB/T 8163 standards, which are widely recognised for automotive and industrial hydraulic components. Typical tensile strength is about 380 MPa for 20# steel and 550 MPa for 45# steel, and a common dimensional tolerance is ±0.1 mm on outer diameter, ensuring consistent performance in high‑stress applications. Standard length for bulk export is 6 m, although other lengths can be arranged on request.
The tubes are used in shock absorbers for cars and motorcycles, bicycle frames, fitness equipment and hydraulic systems in various machinery. OEMs, component manufacturers and equipment integrators are the main buyers. Trade terms such as FOB and CIF are offered, with payment options including L/C and T/T; exact conditions should be confirmed with the supplier before finalising the contract.

Before confirming a purchase, request the mill test report confirming the grade (20# or 45#) and verify the outer‑diameter and wall‑thickness tolerances. Confirm the surface‑finish specification and ask for a surface‑coating certificate if a galvanised or black‑oxide finish is required for the intended service environment.
Agree on the Incoterm - FOB or CIF are commonly used - and obtain a realistic lead‑time estimate based on the supplier’s current production schedule. Payment terms such as L/C or T/T should be documented in the purchase agreement and any advance payment requirements clarified.
Plan a third‑party inspection either at the factory or upon arrival to check dimensional accuracy, wall‑thickness uniformity and surface‑treatment quality. Request the final packing list, certificate of conformity and any required export documentation to ensure smooth customs clearance.
