ABSTRACT:
A modular framework for a drop ceiling constructed from sheet steel strips in which individual frame members are rolled from a single strip into a cross-sectional shape including a hollow rectangular bulb portion, a flat web portion formed from two thicknesses of the sheet metal strip extending from the center of one wall of the rectangular portion, and a pair of L-shaped portions having one leg of each L-shaped portion lying in a common plane transverse to the web portion and joined respectively to the two thicknesses of the web portion, with the other leg of each L-shaped portion extending parallel to the web and projecting away from the bulb portion. Ends of the web portion have tabs which stab into openings of the web portion of another frame member to form a T connection between cross-members.
