Import Galvanized Rectangular Steel Tube — Buy in Bulk from Supplier in China

The Galvanized Rectangular Steel Tube offered by Tianjin Baolai Steel Pipe Co., Ltd. conforms to ASTM A500 specifications, providing a rectangular cross‑section with outside dimensions ranging from 10 mm to 350 mm and wall thicknesses between 1.8 mm and 15.0 mm. The tubes are produced by electric resistance welding (ERW) and receive a hot‑dip galvanised coating for corrosion resistance. Tensile strength meets the ASTM A500 grade B requirement, delivering reliable load‑bearing capacity. The smooth surface finish facilitates welding and finishing operations.

The material is carbon steel that has been zinc‑plated, a standard practice in the structural steel industry to extend service life in both indoor and outdoor environments. Typical industry lengths are 6 m, 9 m and 12 m, and the tubes are frequently supplied in bundled packs on wooden pallets. In addition to ASTM compliance, the product carries ISO and CE certifications, confirming adherence to international quality systems. These attributes make the tube suitable for fabrication shops that demand consistency across large projects.

Primary users include construction contractors, automotive frame manufacturers and general fabricators who require dimensional accuracy and corrosion protection. Tianjin Baolai Steel Pipe Co., Ltd. states that MOQ can be adjusted to project size, packaging can be customised, and shipping is available on FOB or CIF terms. Prospective buyers should request the mill test report and confirm the coating thickness before finalising the order.
