Abstract
A modular sheet metal door structure consists of a plurality of upright modules of the same length which are fixedly connected to one another and have coplanar main webs forming one face of the door. A sheet metal sheath fixedly connected to side webs of the modules forms the other face of the door and has upright marginal portions which closely embrace the modules to form upright door sides. Identical sheet metal header means are fixedly secured to the ends of the modules to provide the ends of the door, and the header means are constructed to be detachably connected to stems by which the door may be suspended from track-mounted carriages for sidewise movement with either end of the door up.
