Abstract
A beam, especially for building houses of wood, comprises a web (1) of steel plate, preferably galvanized steel sheet metal, and transverse flanges (2, 3) constituted by wooden elements (6) arranged on either side of edge portions (4, 5) of the web (1) which have been bent back or folded at least twice. The wooden elements (6) are attached to the web (1) by means of nails (7). Wooden posts (8) are arranged along the web (1) to the web in order to protect the web against buckling. The beam combines the beneficial properties of steel and wood. The steel provides stiffness and stability, while the wood permits nailing.
