Cold-formed steel structural sections are manufactured by using various cold forming processes such as cold-roll forming, brake pressing, bend braking, etc. These cold forming processes bring changes into the material properties of final formed section profiles due to the effect of the cold working that takes place during the forming process, particularly at any formed bends or corners. Cold working causes strain hardening of the material being formed and generally increases yield and tensile stress and decreases ductility. The level of strength increase depends on the type of steel, history of cold working and method of forming used.
