<p>The invention relates to a metal ceiling panel having flange portions with complementary engagement areas formed such that two juxtaposed panels can be interconnected in a tight manner. The shape of the flange portions corresponds to the contour of an inclined S whereby the joint between two such panels becomes even tighter in the event of a substantial increase of the temperature in the space below the ceiling panel. The shape of the flange portions also brigs about an increased stability of an underside covering for a ceiling formed by a plurality of such panels when exposed to a fire.</p> |
