ABSTRACT:
A one-piece rollformed sheet metal structural shape for use in building construction, the shape being a generally triangular closed shape having mounting flanges extending outwardly at the bottom of the triangular shape and stiffening flanges extending outwardly from the opposite end of the shape, the stiffening flanges having a projection extending from the outer extremity of at least one of the stiffening flange(s) for increased stiffness. The stiffening projections may turn over or turn under or overlap the stiffening flanges for increased stiffness, prevention of moisture entering the interior of the shape, and securement of the stiffening flanges to each other providing greater strength to the shape.
