Galvanized Square Tube
Tangshang Group Holding supplies hot‑dip galvanized square tube made from carbon steel with a zinc coating, suitable for structural use. The tube complies with international standards such as ASTM A500 and EN 10219, providing a recognised level of strength and dimensional accuracy. Typical dimensions range from 40 mm × 40 mm to 200 mm × 200 mm with wall thicknesses between 2 mm and 6 mm. Each section is delivered in standard lengths of six metres, weighing roughly 5 kg per metre depending on size.
Hot‑dip galvanising gives a zinc coating of at least 50 µm, which offers corrosion resistance for outdoor and industrial environments. The carbon‑steel base meets the mechanical properties of Grade B in ASTM A500, delivering a yield strength around 240 MPa. These characteristics make the product comparable to typical European and North‑American structural hollow sections. Suppliers often package the tubes in bundled packs on wooden pallets for ease of handling.
Importers typically request FOB or CIF terms and specify a flexible minimum order quantity per metric ton. Payment is usually arranged through a letter of credit, and buyers should confirm the exact size catalogue before placing an order. The tubes are widely used by construction firms, metal‑fabrication workshops, and infrastructure developers seeking durable framing components.

Sourcing Galvanized Square Tube from Tangshang Group Holding - China Import Guide
Before placing an order with Tangshang Group Holding, importers should obtain the complete size catalogue and request a mill test report that details the steel grade, tensile properties and zinc coating thickness. Verify that the dimensions, wall thickness and length match the project specifications, and ask for a certificate of compliance with ASTM A500 or EN 10219. It is also prudent to confirm the supplier’s export‑quality certification and any third‑party inspection reports that may be available.
Typical shipment terms are FOB or CIF from major Chinese ports, and the lead time is usually quoted after the final size and quantity are confirmed. Buyers should negotiate payment via a confirmed irrevocable letter of credit to protect both parties, and clarify whether the price is based on metric tonnage or per metre of tube. Confirm the exact incoterm, vessel schedule and any required documentation such as the commercial invoice and packing list before the goods are dispatched.
Upon arrival, arrange a third‑party inspection to verify dimensions, wall thickness, coating weight and mechanical properties against the supplied certificates. Request a final inspection report and, if needed, a non‑destructive test such as ultrasonic thickness measurement to ensure the galvanised layer meets the agreed specification. Keeping these records alongside the bill of lading will facilitate customs clearance and provide a traceable quality trail for future projects.
