AS1163 Rectangular hollow sections

Rectangular hollow sections are characterized by unequal sides and a uniform thickness, resulting in a rectangular-shaped  steel tube. They are available in various sizes and thicknesses to accommodate different design requirements. RHS includes welded pipe and seamless steel pipe. These sections are typically manufactured through a cold-forming process, where a flat steel plate or coil is formed into a rectangular shape and then welded along the edges to create the hollow section. This process ensures precise dimensions and consistent quality.
