Square Steel Tube-Hollow section
Chief Steel( Shanghai) Trading Co., Ltd. supplies square hollow steel tubes made from carbon steel grades Q235 and Q355. The catalogue lists dimensions from 20 × 20 mm up to 220 × 220 mm, with wall thicknesses ranging between 1.2 mm and 14 mm. Specific sizes such as 20 × 20 × 1.2‑2 mm, 30 × 30 × 1.5‑3 mm and 140 × 140 × 4‑10 mm are quoted in the source data. All tubes are produced to international standards including JIS G3466 and BS EN 10219, giving them a recognised strength‑to‑weight ratio for structural use.
The carbon‑steel grades provide typical tensile strengths of 350‑470 MPa for Q235 and 470‑630 MPa for Q355, with yield strengths of 235‑355 MPa and 355‑470 MPa respectively. Industry practice tolerates dimensional variation of ±0.5 mm and wall‑thickness variation of ±0.2 mm, which aligns with the specifications of these hollow sections. Surface finishes are commonly supplied plain or with a black coating for corrosion resistance, a typical option for outdoor frameworks. These technical attributes make the tubes suitable for furniture frames, infrastructure components and mechanical assemblies.
Importers such as construction firms, fabricators and equipment manufacturers often source these sections for load‑bearing frames and modular structures. The listing does not disclose a minimum order quantity or unit price, so buyers should request exact MOQ and quotation directly from the supplier. Shipping is normally arranged on FOB Shanghai terms, with payment options including L/C or T/T after verification of mill test certificates. Prospective buyers are advised to confirm lead‑time, packaging details and any required certifications before placing an order.

Sourcing Square Steel Tube-Hollow section from Chief Steel( Shanghai) Trading Co., Ltd. - China Import Guide
Before confirming a purchase, verify that the supplied steel grades and dimensions match the project specifications. Request a mill test certificate and a dimensional inspection report to ensure compliance with JIS G3466 or BS EN 10219. Checking the supplier’s harbour‑tier status and low response rate can also help gauge communication reliability.
Logistics for Chief Steel are typically arranged on FOB Shanghai terms.

Accepted payment methods usually include a confirmed L/C or T/T after verification of the quality documents.
Arrange a third‑party inspection at the loading port to validate dimensions, wall thickness and surface finish. Ensure that the inspection agency provides a detailed report covering tolerance compliance and any visual defects.
