Abstract

A method of producing a light steel structural member includes the steps of: forming surface treatment in a piece of sheet material; forming a plurality of embosses in the sheet material; and shaping the sheet material into a predetermined shape to form a light steel structural member. A light steel structural member includes a web portion, and a pair of flange portions. The web portion has a web face. The pair of flange portions each extend generally orthogonally from each side of the web portion. Each flange portion is in a plane that is generally parallel to the plane of the other flange portion. Each of the flange portions has a flange face. At least one of the web face and the flange face has a plurality of embosses formed therein; and at least one of the web face and the flange face has a surface treatment formed therein.
