ABSTRACT:
A light-weight sheet metal door for mobile homes, recreational vehicles, marine vessels and the like in which the bolt-edge of the door has a camber for maintaining a weather tight seal with the door frame. The edges of the door are defined by extruded metallic channel members, and the channel member defining the bolt-edge has been deflected beyond its elastic limit to provide the desired camber. The method of making the door includes the step of feeding the assembled door between forming elements to deflect the bolt-edge beyond the elastic limit of the associated channel member while maintaining the hinge-edge straight.
