The product is a galvanized steel square tube supplied by Tianjin Baolai Steel Pipe Co., Ltd. in China. It is manufactured from carbon steel grades Q235B and Q345B and is hot‑dip galvanized. The tubes are offered with outside diameters from 10 mm up to 350 mm and wall thicknesses ranging between 1.8 mm and 15.0 mm, complying with ASTM A500 and BS EN 10219.
The catalogue includes grades Q235B, Q345B, S235JR, S275JR, STK400 and STK500, each delivering characteristic tensile strengths used in structural frames. Typical industry practice limits dimensional tolerance to ±0.5 mm and wall‑thickness tolerance to ±0.2 mm for these sections. Surface options comprise hot‑dip galvanizing, pre‑galvanizing, black paint or standard paint, providing corrosion protection for outdoor installations. The tubes are frequently cut to length, beveled or threaded according to project specifications.
These square tubes are widely installed in scaffolding, agricultural sheds, fencing and mechanical frameworks where high strength and corrosion resistance are required. Contractors, fabricators and infrastructure developers usually order in bulk and request custom lengths or bevels; the supplier notes that MOQ, incoterms and payment conditions should be confirmed directly. No price or lead‑time details are disclosed, so buyers should obtain a formal quotation and verify any certifications before finalising the purchase.

Before placing an order, buyers should request the mill test certificate that confirms the steel grade, chemical composition and tensile properties of the square tube. It is also advisable to obtain a coating thickness report to verify the hot‑dip galvanizing level. Confirm that the dimensions and tolerances match the project drawings, and ask for a sample if the application is critical. Verifying these details reduces the risk of non‑conformity during fabrication.
The supplier does not list specific incoterms or payment conditions, so importers must negotiate these terms directly. Common practice for steel products includes FOB Tianjin or CIF destination ports, with payment via T/T or LC after shipment documents are issued. Lead‑time can vary based on order size and required processing such as cutting or beveling, therefore a confirmed production schedule should be obtained. Clarifying logistics early helps avoid unexpected delays or additional freight costs.
For quality assurance, request a third‑party inspection report covering dimensions, coating thickness and weld quality if applicable. The supplier mentions capabilities such as precision cutting and beveling, which should be documented in the final inspection checklist. Ensure that the shipping documents include the certificate of conformity, mill test certificate and any relevant ISO or SGS reports that the buyer requires. Proper documentation facilitates customs clearance and validates product compliance.
