Structural Tubing supplied by Threeway Steel Co., Ltd. is a hollow steel section used in load‑bearing structures. The tubing is manufactured from carbon structural steel grades S235, S275, S355, Q235 and Q345. Both square and round profiles are produced using the electric resistance welding (ERW) process. Each section conforms to the specifications of ASTM A500 and EN 10219.
Typical outer diameters range from 20 mm to 200 mm with wall thicknesses between 2 mm and 12 mm. Dimensional tolerances are generally ±0.5 mm on diameter and ±0.6 mm on wall thickness, matching standard industry practice. The mill finish is supplied as standard, and a protective paint coating can be requested as an optional finish. Lengths are normally supplied in 6 m cuts and are bundled on wooden pallets for shipment.
The tubing is widely employed in construction frameworks, fencing systems and support columns where strength and durability are required. Contractors, fabricators and engineering firms are the primary purchasers of this product. Buyers should confirm minimum order quantity, lead time and incoterms directly with Threeway Steel before placing an order.

Before placing an order, verify the steel grade, outer diameter, wall thickness and any required surface coating with Threeway Steel Co., Ltd. Request copies of the ASTM A500 and EN 10219 certificates to confirm compliance with international standards. Confirm whether the mill finish meets your project specifications or if a painted coating is needed, and ask for a sample if possible.
Discuss logistics early by asking the supplier to confirm the preferred Incoterms, typical lead time and payment terms. While the listing does not specify these details, common practice for bulk steel shipments includes FOB or CIF arrangements and payment by T/T or LC. Clarify the exact shipping port in China and any freight forwarder requirements to avoid delays.
Arrange for third‑party inspection or request the supplier’s in‑house test reports covering tensile strength, dimensional tolerance and surface quality. Documentation such as a mill test certificate (MTC) and a packing list should accompany the shipment. Establish a clear acceptance protocol, including permissible deviation limits and the procedure for handling non‑conforming items.
