Structural members having strength properties comparable or superior to those of solid wood are made from a composite wood material comprised of elongated wood flakes bonded together with a binder. The grain direction of the flakes extend generally parallel to their longitudinal axis and the flakes are oriented so that the longitudinal axis of at least a majority is generally parallel to the longitudinal axis of the structural member. The structural member is formed as a solid one-piece unit or assembled from two or more structural components which are made from the composite wood material and are joined together in angular relationship with an adhesive.
