Abstract

A hollow flange section (1) consisting of an open cavity (4) defined by a pair of opposed cavity walls (5) and a cavity base (6). Two enclosed volumes are formed adjacent the cavity by lateral support members (3) extending from a base member (2) to intersect each cavity wall (5). The cavity base (6) and the base member (2) form an integral structure that resists skew deformation of the cavity. The enclosed volumes provide structural support that gives the hollow flange section greater strength. Also described is a composite beam formed from a pair of hollow flange sections with an intermediate web.
The composite beam has greater strength with less mass than comparable prior art beams.
