Abstract
Abstract Disclosed is an insulated metal door edge guard having a stainless steel body, a PVC cover, and a sheet of colored PVF. The PVC cover is coextruded completely around the metal body in strip form. Then, before the heat of the coextrusion step is lost, the PVF sheet is laminated onto one surface of the PVC cover. The combination is then roll formed into a door edge guard having a base and two legs. The ends of the legs are folded inward to form two beads. The PVC cover has two regions of decreased thickness on the interior of the beads to facilitate the roll forming of the beads.
