ABSTRACT:
A metal roof truss for building construction includes top and bottom chord members. Each member is of U-shaped cross-section with each leg of the U having a radiused or rolled hem at the end of the legs of the U. The radiused or rolled hem provides stiffening to the members. In addition, the outward facing surface of the web of the U has dimpled knurling to reduce screw wander.
