ABSTRACT:
A grid tee of the double-web type in which the elements of the web are tied together by a plurality of clinched openings spaced apart along the length of the grid tee. The clinched openings are sized and shaped for receiving wires which support the grid tee from a superstructure of a building. The clinched openings are created in sequential operations of punching holes through the web elements, extruding edge portions of the web elements about the punched holes, and rolling-over the extruded edge portions to clinch the web elements together.
