Square And Rectangular Steel Pipe
Square and rectangular steel pipes are welded hollow sections made from carbon steel grades Q195 to Q345, supplied in both square and rectangular cross‑sections. The product range covers square sizes from 20 × 20 mm up to 300 × 300 mm and rectangular sizes from 40 × 20 mm to 400 × 200 mm, with wall thicknesses between 0.7 mm and 17.75 mm. Lengths are offered from 4.5 m to 13 m and the pipes are available with a hot‑dip galvanized coating of 200 - 400 g m‑2 for corrosion protection. The pipes conform to GB/T 6728, ASTM A500 and EN 10219 standards and are classified as first‑grade quality.
For the Q345 grade, the typical tensile strength is 470‑630 MPa, while the Q235 grade provides a typical yield strength of 235 MPa. Standard weight calculations give an approximate mass of 5 kg m‑1 for a 100 × 100 mm section with 2 mm wall, scaling up to around 150 kg m‑1 for larger dimensions. Surface roughness is usually specified as Ra 0.8‑1.2 µm after galvanising, meeting most structural requirements. The supplier also offers custom lengths and finishes upon request.
These pipes are commonly used in building frames, scaffolding, fencing, furniture, agricultural equipment and low‑pressure fluid transport. Customers such as construction firms, equipment manufacturers and infrastructure developers typically source them in bulk for project‑specific specifications. The listing mentions flexible MOQ and FOB, CFR or CIF incoterms, with payment via T/T or L/C, but exact quantities, lead times and pricing must be confirmed with the supplier.

Sourcing Square And Rectangular Steel Pipe from Handan Zhengda Steel Pipe Co., Ltd - China Import Guide
Prior to ordering, confirm that the supplied pipes meet the required standards (GB/T 6728, ASTM A500, EN 10219) by requesting a mill test certificate and coating weight report. Verify the material grade (Q195‑Q345) and ensure the wall‑thickness tolerance aligns with your engineering specifications. Check that the galvanised coating thickness is documented, especially for applications exposed to harsh environments.
Discuss logistics early: agree on the incoterm (FOB, CFR or CIF), clarify the estimated lead time for production and shipment, and confirm the preferred payment method, typically T/T or L/C. Because the supplier’s public response rate is low, keep a written record of all terms discussed and obtain written confirmation of the agreed delivery schedule.
Arrange for a pre‑shipment inspection by an independent third‑party agency to verify dimensions, mechanical properties and coating quality. Request the full set of documentation, including the certificate of conformity, test reports, and any required customs paperwork for import into your country. Maintaining these checks helps ensure that the steel pipes meet project requirements and regulatory standards.
