Abstract
A light steel structural member includes a web portion and a pair of flanges. The web portion has a web face. The pair of flange portions each extend generally orthogonally from each end of the web portion. The flange portions each having a plane and the planes are generally parallel each other and each flange has a flange face. At least one of the web face and the flange face has a plurality of embosses formed therein. In another embodiment the light steel structural member further includes a pair of restraining ribs. In a further embodiment the light steel structural member further includes a pair of lips and a pair of multi-cranked stiffeners. A method of making the light steel structural members is shown.
Claims68
A light steel structural member having a longitudinal axis comprising:
- a web portion having a web face having opposite longitudinal sides;
- a pair of flange portions each extending generally orthogonally from each end of the web portion, the flange portions each being in a plane that is generally parallel to the plane of the other flange portion, each of the flange portions having a flange face having opposite longitudinal sides;
- and
- wherein at least one of the web face and the flange faces has a plurality of segmented embosses formed therein, the segmented embosses having spaces between adjacent embosses and being arranged in generally parallel rectilinear rows, the spaces between the embosses of one row being offset with spaces between the embosses of at least one other row such that any cross section extending transversely to the longitudinal axis of the structural member and connecting the opposite sides of the at least one face intersects at least one of the embosses on the at least one face, the plurality of segmented embosses being portions of steel stretched out of plane one of inwardly and outwardly, being connected around the whole periphery and each emboss is fully contained within at least one of the web face and the flange faces.
