摘要： A door comprising two metal panels and an internal core structure. The panels have their edges formed around a perimeter sub-frame of channel construction, the base of the channel being internally adjacent the respective edge of the door. Opposing edges of the panels are seam welded together to provide a flush finish, and the base of the channel is apertured to act as a heat sink and to allow weld gas to escape.
