Plastic paneling on metallic door frame

A door structure, comprising

• a) a metallic door frame, having opposite sides,
• b) plastic paneling received on the metallic frame in covering relation with at least one of said sides,
• c) there being two spaced apart stile components extending vertically and at least one rail component having edges abutting edges of said stile components,
• d) said plastic paneling defining rail and stile door components, and said metallic frame including rail and stile door components,
• e) the plastic paneling stile components extending closely and completely about the metal frame stile components, and the plastic paneling rail components extending closely and completely about the metal frame rail components,
• f) the plastic paneling stile components defined by first plastic extrusions slidably and guidedly received onto the metal frame stile components, and the plastic paneling rail components defined by a second plastic extrusion slidably and guidedly received onto the metal frame rail components, there being outwardly tapering protrusions projecting normal to flat side walls defined by the metal frame stile, and rail components into open spaces between the side walls of plastic and metal extrusions and toward plastic wall surfaces for acting as guides for said sliding for close interfitting, the protrusions projecting from at least three sides and spaced from the corners of the stile and rail components, one side of the walls of both the plastic and the metal extrusions being slidingly engaged without protrusions,
• g) there being threaded fasteners directly holding the second plastic extrusions endwise to the metal frame rail components.
