Carbon Rectangular Steel Tube
Tianjin Baolai Steel Pipe Co., Ltd. supplies carbon rectangular steel tubes manufactured in Tianjin, China. The tubes are produced by an ERW process and conform to ASTM A500 and BS EN39 standards. Available grades include Q235B, Q345B, S235JR and S275JR, with outside dimensions from 10 mm up to 350 mm and wall thicknesses between 1.8 mm and 15.0 mm. The supplier also lists additional grades such as STK400 and STK500 in its catalogue.
Typical industry practice for structural steel tubing uses hot‑dipped galvanised, pre‑galvanised, black or painted finishes, and Baolai offers all these surface options. Dimensional tolerances of ±0.5 mm and length tolerance of ±5 mm are common for this product class, providing reliable fit for construction frames. The company can cut tubes to any length, apply bevels of any required angle, and provide threading compatible with fluid and gas conveyance. These capabilities align with standard fabrication requirements for scaffolding, bridges and mechanical assemblies.
Importers usually request bulk quantities for export, and Baolai states that competitive pricing is available for large orders with global shipping arrangements. Payment and Incoterm details are not disclosed in the listing and should be confirmed directly with the supplier. The firm operates two factories - a pipe‑manufacturing plant and a pre‑galvanising facility - allowing integrated processing. Potential buyers include construction contractors, equipment manufacturers and infrastructure developers seeking reliable rectangular steel sections.

Sourcing Carbon Rectangular Steel Tube from Tianjin Baolai Steel Pipe Co., Ltd. - China Import Guide
Before placing an order, verify the exact grades, dimensions and surface finishes required for your project and request material test reports that confirm compliance with ASTM A500 and BS EN39. Because the supplier’s response rate is currently zero, consider conducting a preliminary audit of the factory or requesting third‑party inspection reports to ensure production capability and quality control processes are satisfactory.
Logistics for bulk steel tubes are typically arranged via sea freight from Tianjin ports, with Incoterms such as FOB Tianjin or CIF Shanghai commonly used. Lead‑time, payment terms and any required export documentation are not disclosed in the listing, so these must be agreed with the supplier in advance. Discuss container loading plans, weight limits and any special handling requirements to avoid unexpected freight charges.
When importing, arrange for pre‑shipment inspection to check dimensions, wall thickness, surface finish and tensile properties against the agreed specifications. Upon arrival, request the mill test certificate, heat number traceability and coating thickness report. Establish a post‑delivery quality protocol that includes random sample testing and a clear warranty claim procedure with the supplier.
