The invention discloses a
metal door and a manufacturing method thereof, and the method comprises the steps: respectively
punching hollow
grating assemblies on two
metal plates according to preset shapes and depths to obtain two
metal door skins;
filling materials are placed in the metal door
skin where the framework is placed; glass is placed in the reserved glass holes in the filling material, and one face of the glass corresponds to the hollowed-out
grating assembly; the other metal door
skin is placed on the framework where the filling material and the glass are placed, and the hollowed-out
grating assembly is located on the other face of the glass; and pressing by a press. According to the metal glass door, the hollowed-out grating
assembly which is integrally formed with the metal door
skin in a
stamping mode is used for replacing a
glazing bead on a metal glass door in the prior art, hollowed-out grating assemblies of any shape and depth can be stamped according to design requirements, metal glass
doors of any style can be manufactured, time and cost for manufacturing the
glazing bead are saved, and the manufacturing cost is reduced. The hollowed-out grating assembly and the metal door skin are integrally formed in a
punching mode, so that the surfaces of the hollowed-out grating assembly and the metal door skin are flush, transportation space is saved, firmness and durability are achieved, and cost is reduced.
