A ceiling panel 6 has on each of two longitudinal sides at least one protrusion (24, 26) having a transverse edge (36, 38). The transverse edges are aligned with each other and constitute swing bearing surfaces on which the ceiling element may be swung down from its normal horizontal position in the false ceiling and suspended on two spaced parallel support rails in a generally vertical open position. The ceiling element is constructed of a single metal plate with stamped bent-off edge sections that form the protrusions that permit displacement of downward swung ceiling panels in the longitudinal direction of the support rails, and strengthen the ceiling panel so that it may have large longitudinal and transverse dimensions.
