ABSTRACT:
A steel door fabricated of sheet steel and having inner and outer end panels retained in spaced relation by inwardly-bent vertical edge portions has a plurality of inwardly-swaged recesses spaced along one edge of the door for the flush reception of hinge plates securable in place by the use of sheet metal screws received in bent sheet metal hinge support plates fixed within the door behind each of the recesses. The hinged edge of the door is formed along its length with a central, outwardly-extending portion of rectangular cross-sectional configuration along which the hinge plate recesses are formed and which, at the inside of the door, define side-wall portions within which complementary side wall portions of the bent metal hinge support plates are snugly received.
