Abstract (en)
[origin: WO9117328A1] A fabricated structural beam (10) comprises at least one longitudinally folded member having a web portion (16) and a head portion (12, 14). In different embodiments, a plurality of folded members may be interleaved with one another to provide configurations of varying load carrying capabilities. In all cases, the folded head portion (12, 14) is made rigid by forming it into a tube that is closed on all sides. This is accomplished by fastening the folded material upon itself in the web portion (16).
