Abstract:
A balanced, single-layered web beam for a grid in a drywall suspended ceiling, wherein opposing flanges at the bottom of the web are cantilevered directly from the bottom of the web. When the flanges are equally loaded by the drywall sheets, the resultant load on the beam passes through the vertical plane of the web, so the beam does not twist or bend.
