ABSTRACT:
An elongated beam is constructed from a sheet metal panel and has upper and lower flange sections integrally connected by a web section. The web section has upper and lower inclined web portions which project in opposite directions from a vertical intermediate web portion and cooperate to provide the beam with a generally Z-shaped cross-sectional configuration to facilitate stacking of a plurality of beams in interfitting nested relation. The upper and lower flange sections are stiffened by members which may be longitudinally extending sheet metal strips or longitudinally spaced stiffening elements, and the upper and lower flange sections and adjacent portions of the web section are formed slightly different in size to permit interfitting of mating overlapping end portions of two longitudinally aligned beams after one beam is inverted relative to the other.
