Tianjin Baolai Steel Pipe Co., Ltd. supplies carbon steel tubes that meet ASTM A500 ERW structural specifications. The tubes are manufactured from mild steel with a maximum carbon content of 0.26 % and manganese not exceeding 1.35 %. Available outside diameters range from 10 mm to 350 mm and wall thicknesses from 1.8 mm up to 15 mm, covering square, rectangular and round profiles. Each product is produced by electric resistance welding and can be supplied with mill test certificates.
In the steel tube market, ASTM A500 Grade B typically delivers a tensile strength around 310 MPa, which aligns with the mechanical requirements of many structural projects. Standard industry tolerances for diameter are ±0.2 mm and for wall thickness ±0.1 mm, providing predictable dimensional accuracy. Typical surface condition is hot‑rolled, and standard packaging involves bundling the tubes on pallets for safe handling during transport. These characteristics make the product compatible with bridges, scaffolding, and machinery frames where strength‑to‑weight ratio is critical.
Buyers such as construction contractors, equipment manufacturers and infrastructure developers commonly import these tubes for load‑bearing applications. The supplier offers flexible order quantities and can arrange shipment in either bundled or loose form, subject to confirmation of incoterms and payment terms. Prospective purchasers should request the latest ISO certificates and mill test reports to confirm compliance before finalising the contract.

Before placing an order, importers should confirm that the tube dimensions, material grade and chemical composition match the project requirements. Request the mill test certificate and the ISO certification referenced by the supplier to validate compliance with ASTM A500. Verify the supplier’s harbour trust tier status and ask for recent factory audit reports or third‑party inspection results. Clarify any minimum order quantity or packaging preferences early to avoid misunderstandings.
Discuss the preferred incoterm with the supplier, such as FOB Tianjin or CIF a destination port, to align responsibility for freight and insurance. Ask for an estimated production lead time and shipping schedule, noting that the supplier has not disclosed a specific timeframe. Payment terms are typically negotiated on a letter of credit basis for bulk steel orders, but the exact conditions should be agreed in the contract. Ensure that packaging - bundled on pallets or loose - matches the handling capabilities at the receiving port.
Arrange for a pre‑shipment inspection by a recognised third‑party agency to verify dimensional tolerances, wall thickness and surface condition. Request a full set of documentation, including the mill test report, certificate of origin, and a packing list detailing tube lengths and weights. Upon arrival, conduct a sampling test to confirm tensile strength and chemical composition against the supplied certificates. Maintaining these checks helps mitigate the risk of non‑conforming material entering the supply chain.
