Abstract: A metal door includes a pair of sheet metal door panels. Each of the door panels includes a central body portion with top, bottom and opposing side edges. The doors include an integral flange along each side edge of each panel. The integral flange extends generally perpendicular to the central body portion. An integral inturned lip can be located along each flange and extend substantially parallel to the central body portion. The door panels are positioned such that the central body portions are in an opposing spaced apart relation to one another with the flanges adjacent to and aligned with one another. The inturned lips are positioned in contacting face-to-face relation. The metal door also includes an elongate connector overlying and clamping together each face-to-face pair of inturned lips to maintain the door panels in assembled relation.
