ABSTRACT:
A method of forming a pair of sheet metal structural members simultaneously from a single elongated strip of sheet metal defining parallel side edges and comprising the steps of severing the strip sheet metal along a predetermined zig-zag separation path, thereby dividing the strip into two strip portions on opposite sides of the zig-zag separation path, each having generally zig-zag edges the zig-zag edges being in generally inter-fitting relation; forming edge flange formations along the zig-zag edges of each of the strip portions at an angle thereto, and, forming linear edge formations along the parallel side edges of the strip portions.
