Fire doors generally have a frame made from at least two different profiles of metal. The two profiles are joined together via securing members which protrude from the frame, these protruding parts consisting of screw heads, which may cause injury. According to the present invention, these protruding heads are avoided because the frame's outer profile 5, which forms the outer contour of the frame, has, inside its outer surface, a support flange for securing members 7 which cooperate with a profile 1 in the frame arranged inside the outer profile 5 of the frame. <IMAGE> |
