Abstract
Abstract A component for erecting buildings and the like comprises a channel member preferably having a substantially squared-off C-shaped cross section with web portion, two flange portions on the web portion and two inwardly directed lips on the flange portions. A repeating pattern of longitudinally spaced large diameter apertures is provided in the web portion. A longitudinally repeating pattern of small diameter apertures is also provided in the web portion. A longitudinally repeating pattern of apertures is provided in each flange portion including a pentad with an aperture at four corners, defining an imaginary square and an aperture at the center of the square. A plurality of apertures is also provided in the inwardly directed lips. The building component is widely adaptable to a variety of different uses in building construction systems and for innumerable building designs.
