For the same overall dimensions and wall thickness, the section properties for square and rectangular hot-finished and cold-formed sections are different because the corner radii are different. Steel Hollow Sections are providing to be the most versatile and efficient form of structural steel for construction and mechanical applications. For typical Rectangular Hollow Sections (RHS) the geometric properties of the cross-section are defined in the following standards: EN 10210-2: Hot finished structural hollow sections of non-alloy and fine grain steels, EN 10219-2: Cold formed welded structural hollow sections of non-alloy and fine grain steels.
