Abstract
A flexible ceiling panel is preferably formed from sheet metal, such as aluminum sheet. Each ceiling panel has a generally rectangular shape (corresponding in width to the spacing between the main runners) and is formed with a hem on all four edges. A series of bendable tabs are formed integrally with the hem of the panel. To secure the panel to the associated grid system, the tabs are folded upwardly and outwardly from the panel along two axes to secure the panel to the grid system. Alternatively, a plurality of separate spring clips is used to secure the panel to the grid system. Each clip includes a first leg adapted to have at least a portion thereof received in the hem of the ceiling panel. A second leg extends generally perpendicularly from the first leg and includes a detent extending toward the first leg, the detent being adapted to secure the clip to the flange of the runner.
