The product offered is a hot‑dipped galvanized steel square pipe manufactured from carbon steel grades Q195, Q235, Q345 and A500 (20#, 45#). Pipe dimensions range from 20 mm × 20 mm to 200 mm × 200 mm with wall thicknesses between 1.5 mm and 12 mm, and standard lengths are supplied between 4 m and 12 m. The zinc coating is applied at a weight of 180‑300 g/m², providing corrosion protection. The pipes conform to ASTM A53‑2007, ASTM A106‑2006 and BS1387 specifications.
These grades are common in structural steel applications where yield strength between 235 MPa and 345 MPa is required. Typical tensile strength for Q345 steel is 370‑500 MPa, which aligns with the performance expected from hot‑dip galvanized sections. In the industry, a coating weight of 180‑300 g/m² corresponds to a typical zinc thickness of about 55‑95 µm, delivering a service life of 30‑50 years in moderate atmospheres. The dimensional tolerance is usually ±0.5 mm, and standard packaging bundles the pipes in 10‑12 m lengths wrapped in steel band.
The pipes are used in construction frames, bridge components and infrastructure utilities where durability and corrosion resistance are critical. Importers should note that the supplier lists a flexible minimum order quantity and can provide either bulk or containerised packing, but exact MOQ must be confirmed directly. Shipping is typically arranged on a CIF or FOB basis from Chinese ports, with lead times dependent on order size. Buyers are advised to request mill certificates and coating thickness test reports before finalising the purchase.

Before placing an order, verify that the pipe dimensions, wall thickness and zinc coating weight match the specifications you require. Ask the supplier to supply a mill test certificate that confirms compliance with ASTM A53, ASTM A106 and BS1387, as well as a coating thickness report. Confirm the supplier’s production capacity and whether they can meet your required quantity within the project schedule.
Logistics should be clarified early; typical shipments originate from Chinese ports and can be arranged on FOB or CIF terms. Lead times are generally linked to order size and factory scheduling, so request an up‑to‑date delivery estimate. Payment methods such as L/C, D/P or T/T are mentioned, but confirm the exact incoterm and any advance payment requirements before signing a contract.
When the goods arrive, arrange a third‑party inspection to check dimensions, wall thickness and zinc coating weight against the agreed tolerances. Verify the presence of a valid mill test report and, if needed, conduct a corrosion resistance test on a sample. Proper documentation, including a certificate of origin and packing list, will facilitate customs clearance and ensure product quality.
