A Square Steel Tube is a metal product shaped into a square cross-section. Its dimensions are determined by measuring the equal-sized outer sides and the thickness of the walls. This type of steel is readily weldable, malleable, and easily cut, allowing for various shaping processes. Additionally, it can undergo a galvanized coating process, enhancing its resistance to corrosion and rust compared to other steel varieties.

The versatility of square steel tubes makes them suitable for applications in construction and structures, such as road signs, towing lathes, and supporting skyscrapers and bridges. Notable advantages include a high cost-performance ratio, impressive strength, and uniformity in quality.
