Square Tube
Tianjian Xinyue Steel Group offers square hollow sections made from stainless steel, available in grades 304, 316 and 321. The tubes comply with ASTM A500 and A554 standards and are supplied in nominal sizes ranging from 20 mm to 100 mm. Each tube is a hollow structural section with a square cross‑section, suitable for load‑bearing applications. The supplier highlights that the product is packaged in bundles or on pallets for secure transport.
In the steel industry, typical wall thickness for this size range is 2 mm to 6 mm, providing a balance between strength and weight. Typical dimensional tolerance is ±0.5 mm, and the surface finish is usually a mill finish that can be further processed by polishing or coating. Standard density for stainless steel is about 7.9 g·cm‑3, and the corrosion resistance varies by grade, with 316 offering superior performance in marine environments. These typical characteristics help designers select the appropriate tube for structural or chemical‑process applications.
Primary users include construction firms, machinery manufacturers and chemical‑plant engineers who need reliable corrosion‑resistant components. The product can be ordered in bulk, loaded onto pallets and shipped under FOB or CIF terms, with the exact minimum order quantity to be confirmed with the supplier. Buyers should request a mill test report to verify grade and mechanical properties before finalising the purchase. All trade specifics, such as incoterms and lead‑time, must be negotiated directly with Tianjian Xinyue Steel Group.

Sourcing Square Tube from Tianjian Xinyue Steel Group - China Import Guide
When initiating a purchase, verify the mill test report to confirm the exact grade, dimensions and mechanical properties of the square tube. Confirm the supplier’s registered address in Tianjin and ensure that the harbour trust tier status matches your compliance requirements. Request clarification on the minimum order quantity and any sampling options before committing to a full order.
Logistics for the square tube usually involve loading the palletised bundles onto container vessels from the Tianjin port, with FOB or CIF incoterms commonly applied. Lead‑time is generally 4‑6 weeks after order confirmation, but the exact schedule should be confirmed with Tianjin Xinyue. Discuss payment terms such as T/T or L/C and obtain a pro‑forma invoice reflecting the agreed incoterms.
Quality assurance should include third‑party inspection of the tube dimensions, wall thickness and surface condition, as well as verification of the mill test report. Buyers are advised to request certificates confirming compliance with ASTM A500/A554 and any applicable ISO standards. Maintaining thorough documentation will support customs clearance and downstream engineering approvals.
