Liaocheng Huijia Import And Export Trading Co., Ltd supplies square steel tubes made from carbon steel grades such as Q195, Q235, Q345, SS400 and STK500. The product range covers cross‑sections from 20 × 20 mm up to 400 × 400 mm with wall thicknesses between 2 mm and 20 mm. Standard lengths are offered from 3 m to 12 m, and custom lengths can be requested. All tubes are produced in China and are ready for export from the port of Tianjin.
The tubes are available in plain, beveled, black‑painted or hot‑dip galvanized finishes according to buyer requirements. Manufacturing processes include seamless, electric resistance welding (ERW) and cold‑drawn techniques, providing good dimensional stability. Typical industry tolerances for square sections are ±0.5 mm on overall dimensions and ±0.2 mm on wall thickness, which the supplier meets under ASTM, ASME, DIN, GB, JIS and BS standards. Inspection services such as SGB, BV, Lloyd’s, hydraulic testing, eddy‑current and infrared testing are offered to verify mechanical properties and surface quality.
Buyers in construction, bridge building, machinery manufacturing and chemical plant projects commonly order these tubes for load‑bearing frames and shelving. The company can supply up to 10 000 ton per month, packs the products in square bundles with seaworthy export packing, and welcomes small or non‑standard orders. Trade terms include L/C or T/T payment and delivery times ranging from 15 to 60 days depending on order size.

Before placing an order, confirm the exact cross‑section size, wall thickness and finish required, and ask the supplier to provide the relevant mill test certificates that reference the ASTM, ASME or GB standards cited. Verifying the coating type and any surface‑treatment specifications will help avoid mismatches during fabrication.
Logistics should be clarified by confirming the port of loading - Tianjin - and the preferred Incoterm, typically L/C or T/T with FOB terms. Lead‑time estimates vary from 15 to 60 days depending on order volume, so request a detailed delivery schedule. Payment conditions and any required advance deposits must be agreed in writing before production begins.
Arrange a third‑party inspection if required by your import regulations; the supplier can supply inspection reports from SGB, BV or Lloyd’s, as well as hydraulic, eddy‑current and infrared test results. Ensure that packing lists, commercial invoices and any required certificates of origin are prepared for customs clearance. Maintaining clear documentation will streamline the import process and reduce the risk of delays.
