Square Steel Tube – High Strength Hollow Section for Construction & Machinery
Square Steel Tube – High Strength Hollow Section for Construction & Machinery
Square steel tube, also known as square hollow section (SHS), is hollow rectangular structural steel with square cross-section. It features high torsional resistance, neat appearance and stable load-bearing capacity, widely favored in global construction, metal frames and industrial manufacturing.
Our product range covers black hot finished square tubes and pre-galvanized square tubes. Complete size and wall thickness options are available, custom fixed-length cutting supported. Main grades include Q235B, Q355D, S355J2H, fully compliant with EN10210, EN10219, GB and ASTM standards.
Excellent weldability and bending performance make square tubes ideal for warehouse frames, building supports, guardrails, machinery frames, truck chassis and outdoor engineering projects. Galvanized types provide superior anti-rust performance for humid coastal areas.
Every shipment is equipped with EN10204 3.1 MTC mill test certificate, with consistent batch and heat number matching the physical goods to meet overseas inspection standards.
We maintain abundant spot inventory for bulk export orders. Shipment departs from Qingdao Port via container or bulk vessel, supplying Africa, Southeast Asia, Central Asia and European markets with factory-direct competitive prices.
