A beam having a gooseneck shape with two gooseneck portions. The beam may have a variety of cross sectional configurations. One such configuration has an upper front wall, a lower front wall, and an offset wall there between. The offset wall may be recessed, or offset away from the body of the beam. Also disclosed is a method of manufacturing the gooseneck beam by positioning a length of a material on a flat surface of a two-cam rotating member; gripping said material with said two-cam rotating member; restraining said length; rotating said two-cam rotating member to form a first and second; and pressing a portion of said material.
