Choosing the right steel square pipe starts with a reliable direct manufacturer. With years of production experience, we supply square and rectangular hollow sections (RHS/SHS) for construction, infrastructure, machinery, and structural fabrication. Every product is manufactured with strict process control to ensure consistent strength, dimensional accuracy, and dependable performance from production to installation.

    Our square steel tubing is available in outer dimensions from 20×20 mm to 300×300 mm, with custom sizes produced on request. Wall thickness ranges from 1.5 mm to 16.0 mm to meet both standard and heavy-duty engineering requirements. We manufacture mild steel, carbon steel, stainless steel, and pre-galvanized or hot-dip galvanized square pipes, as well as black steel finishes, giving customers flexible solutions for different environments and corrosion protection needs.

    Every production batch is inspected for dimensional tolerances, weld integrity, surface quality, and mechanical properties before shipment. Supported by advanced ERW/HFW production lines and an experienced technical team, we provide stable manufacturing capacity, competitive factory-direct pricing, and efficient worldwide delivery. As a trusted manufacturer and supplier, we also offer mill test reports (MTR), custom specifications, and responsive technical support to help customers select the right square steel pipe for every application.
