摘要： A metal door has a unitary rectangular frame of generally uniform cross section providing stiles and rails, and a pair of substantially rectangular panels which are secured to the frame. The panels have opposed flanges overlying and engaged with the adjacent side margins of the stiles of the frame to secure the panels thereto. The door is fabricated by forming an elongate metal strip into a frame element of generally uniform cross section with channels between a generally planar central portion and inwardly offset marginal portions. A predetermined length of the strip is bent to form a substantially rectangular frame, the ends of which are fastened together. The panels have lips on their flanges and are assembled to the frame with the flanges inserted into the channels and the lips frictionally engaging the side walls thereof.
