3. In a structural member, the combination of a central member comprising a plate having parallel enlarged edges and pairs of laterally extending flanges adjacent said edges, and a pair of side members at right angles to the central member, each comprising a plate having parallel flanges extending from one side and spaced to receive the enlarged edges of the central member, the parallel flanges of the side members being bent to fit around-the enlarged ed es of the central member and the flanges 0 the central member being bent down parallel to each other against the flanges ,of the side members.
