ABSTRACT:
A metal beam with a thermal break between opposite sides and method of making is disclosed. In a first embodiment a huck rivet extends through aligned holes in a pair of opposed beam sections having a base wall portion and a side wall portion. In a second embodiment a punch/swedge operation forms a rivet in the base wall portion of one beam section that extends through the other base wall portion of the other beam section. In a third embodiment a series of spaced, alternating tabs and recesses are formed in the beam section and the tabs overlap and are riveted at overlapping tabs only to form a gap in the formed beam. In a fourth embodiment oppositely opening hooks are formed in the inner sections of first and second beam sections that interfit and are seamed together to fasten the two beam sections with a continuous seam along the center of a composite beam.
