ABSTRACT Disclosed is a modular sheet metal door structure com- prising, in combination, a plurality of upright sheet metal modules of the same length fixedly connected to one another with the modules having coplanar main webs forming one surface of the door. Lateral modules of the plurality have an inner side web perpendicular to the main web, a connecting web integral with the inner side web which extends toward the vertical median plane of the door in a plane parallel to the main webs, and an outer side web parallel to the inner side web and narrower than the inner side web. A median one of the modules has parallel side webs with edges facing the connecting webs of adjacent lateral modules which are directly connected to it. A sheet metal sheath abuts; and is fixedly secured to the connect- ing webs to form the other surface of the door and sheet metal header means is fixedly secured to the upper and lower ends of the modules to provide the ends of the door.
