Abstract
A method for forming a frame from an elongate strip of formable material and products formed thereby are disclosed. The method comprises the steps of notching the side edges of an elongate strip and providing slots in one edge; thereafter deforming the strip along four parallel lines which become the interior corners of frame members having a substantially rectangular cross section. A pair of complementary corner notches, each formed of a particular shape, allow the strip to be folded or deformed transversely of its length dimension, thereby forming a pair of intersecting frame members each having a substantially rectangular cross section defined by a front wall, parallel inside and outside side walls and a pair of flanges. The inside flange and side wall of each frame member provide a plurality of slotted openings spaced equal distances apart to receive the ends of steel rods which are interlaced and form a wire meshed screen.
