Abstract
A metallic frame and, more particularly, a stainless steel door frame has a bent sheet metal frame element encompassing an inner space and the element has backbends which extend perpendicularly inward from the back ends of faces of the element. At least one slidably insertable sleeve is disposed inside the element and has flanges which are spot welded to the back ends. The sleeves serve as carriers for various door hardware such as hinge reinforcement and strike plates, clips having bendable tabs, and anchors.
