Abstract (en)
[origin: US2020378116A1] A suspended ceiling grid main runner is provided that has a cross-section generally in the form of an inverted T, with a central web, a pair of panel support flanges extending from one edge of the web, and a reinforcing bulb extending from the other edge of the web. The main runner includes an integrally-formed interlocking connector, first and second series of longitudinally extending, spaced apart stitches in the web adjacent to the bulb and flanges, hemmed flanges including a cap, and an enlarged reinforcement bulb, which together increase the structural strength of the main runner sufficient to compensate for a reduction in the thickness of the metal strip from which the main runner is formed.
