Abstract

The invention is a cold formed, steel metal C-shaped structural member having an elongated web member with novel opposing angular intervening web extensions with variable exaggerated bends and extending laterally to opposing perpendicular flange members and extending to opposing end stiffening lips parallel to the center web member at the cross sectional ends.

1 . A metal structural member comprising: 
 an elongate web member having a first side and a second side; 
 a pair of angular intervening web extensions in the adjacent corners of the elongate web member, wherein the angular intervening web extensions having variable exaggerated bends and extending to opposite parallel flanges that are perpendicular to the elongate web member and terminating with stiffening lip members parallel to the elongate web member forming a structural member of a generally C-shaped cross section.  
   
   
   
       2 . The metal structural member in accordance with  claim 1  wherein two structural members can be abutted along the outer longitudinal wall of the members for increased lateral resistance.  
   
   
       3 . The metal structural member in accordance with  claim 1  wherein two structural members can be abutted along the outside parallel lip as a composite truss vertical beam or a structural component for increased lateral resistance.  
   
   
       4 . The metal structural member in accordance with  claim 1  wherein two structural members can be snapped-fit together and overlapping as a closed channel forming a composite truss vertical beam or a structural component for increased lateral resistance.
