As shown in FIG. 1A of the drawings, a metal ceiling plate is installed in a humid ceiling structure such as a parking lot and a bathroom of a conventional building.

The metal ceiling plate is constructed by mounting a suspension frame with various channels and clips from the anchor member suspended from the slab ceiling as shown in FIG. 1B, and then mounting the ceiling edges of the ceiling plate.

The metal ceiling plate constituting the ceiling of such a ceiling structure was designed by stamping the plate into various designs, cut to the designed size and dimensions, bent again, and finished by welding the four corners.

Therefore, the edge of the deterioration due to the welding was left, the product had to be painted, and additional expenses were generated due to the welding of the weld.

Recently, it is impossible to construct a ceiling with a metal ceiling plate made of a metal color of a metal plate such as aluminum or stainless steel.

In addition, a process having a step of simply pressing, cutting, and bending the rolled plate body in turn is possible as a mechanical molding apparatus, but in order to combine the edges, the edges may be welded as separate welding machines after bending. Since the end is made through a predetermined bending process, there is a problem that the welding worker has to weld by hand manually because the welding is impossible.

Therefore, there is a need for a method of joining corners to a metal ceiling plate without such a manual welding process, and a ceiling plate structure capable of achieving all processes of cutting, pressing, bending and joining as one molding apparatus has been required.

It is an object of the present invention to provide a metal ceiling plate in which the edge coupling of the metal ceiling plate is fitted without being welded.

Another object of the present invention is to provide a method of manufacturing a metal ceiling plate in which a process of stamping, cutting, bending, and joining is performed in one molding apparatus.
