Abstract
A steel stud member for use in supporting structures and having reduced thickness as compared with conventional studs, and having a web having side edges, flanges on the side edges, formed at angles to the web, the web and the flanges enclosing inside surfaces, and having outside surfaces for mounting structure, and plurality of narrow indented longitudinal ribs formed in the flanges, and in the web, indented inwardly from the outside to the inside of the flanges, providing greater load bearing capacity for a given gauge of steel. Also disclosed is a method of making such a steel member.
Claims20
A reinforced indented sheet metal stud (10) for use in construction and having a web (12) defining side edges and an axis, a first flange (14) along one side edge, and a second flange (16) along the other side edge, said web and said flanges defining inside surfaces and mounting surfaces opposite one another, and being characterized by;
- longitudinal indented ribs (20) formed along at least one of said first and second flanges, parallel to said web axis and,
- and wherein said indented ribs in said flanges are formed as depressions from said mounting surface extending into said inside surface, to avoid obstruction of said mounting surfaces of said flanges.
A method of making a reinforced indented sheet metal stud characterized by the steps of;
- forming a sheet metal strip having a web (12) with side edges, and flanges (14, 16) along each said side edge,
- forming longitudinal indented ribs (20) in said web
- forming longitudinal indented ribs (18) in said flanges,
- bending said flanges relative to said web whereby to define a mounting surface and an inside surface of said stud, said ribs being formed as depressions indented from said mounting surface into said inside surface, and, bending lips on said flanges.
