<p>The invention provides lightweight metal studs and tracks for use in wall framing systems produced by passing flexible thin steel between rolls, thereby forming a C-shaped member with defined longitudinal support ribs or projections on the stud members and transverse support ribs or projections on the track members that both increase the span strength, automatically spaces the vertical stud members and locks the stud members into place along the track member with a frictional fit.</p> |
