ABSTRACT:
A beam for a triangular wall section of a geodesic dome structure is made from a single rectangular sheet of metal. The longitudinal side edges of the metal sheet are bent to form a parallel pair of side walls that are non-perpendicular to the flat central base section that lies between them. The extremities of the side walls are curled inwardly. Each end of the beam thus formed is cut along a plane which lies perpendicular to the side walls but at an acute angle to the base section. Holes are formed in the base section for bolting it in back-to-back relation to the base section of another similar beam.
