Cold-Formed Square Hollow Sections - 250x250x12.5

Cold-formed square hollow sections (SHS) are symmetrical, box-shaped steel tubes created by rolling and shaping flat steel sheets at room temperature before welding the edges together. This cold manufacturing process hardens the metal, which increases its overall strength and ability to carry heavy loads. Because they have a perfectly square profile, they offer equal strength and resistance to bending in all directions. Their flat, neat sides also make them incredibly easy to cut, weld, and connect to other flat materials, making them highly popular for building frames, columns, and structural steelwork.
