  • Patent number: 4691494
    Abstract: A metal framing system for building structures wherein the members have continuously roll formed and fabricated "C"-shaped, "T"-shaped, and "I"-shaped cross sections and wherein the flanges at their distal edges excluding plate members, include a roll formed multi-purpose end and surface fastener recess extending the length of the member. These recesses are adapted to supportedly receive threaded fasteners for use in conjunction with both interconnection of pre-punched transverse plates at the ends of the members and also for attachment of wall covering against the flanges of the members. This recess and extended distal edge, while providing full functional flange width, also eliminates "Q" column flange loss while substantially stiffening the distal edge of the flange. "C" section studs and joists members may have two additional end fastener recesses added to the webs where a total of four fasteners are required per member for attachment to plates.
