ABSTRACT:
An extruded metal structural component has a hollow generally rectangular section with the sides of the rectangular section adapted to interlock and engage with other structural components of the same cross section. The generally rectangular section includes on one side a shallow “U” shaped channel and the opposite side includes a projecting portion for mating receipt in the “U” shaped channel of a second structural component. The structural component includes a downwardly extending securing flange for engaging and securing connecting members when two such structural components form the top and bottom chord of a structural beam.
