ABSTRACT:
A method is provided for pultruding a glass reinforced plastic door panel that is field alterable to fit an out-of-true frame. A mixture of reinforcing fibers and resin is pulled through a set of dies to form a panel having a pair of face sheets that are spaced apart by a hinge side stile at one panel edge and a strike, or lock, side stile at the other panel edge. The hinge side stile is arranged perpendicularly to the face sheets to form a closed panel edge, and the strike side stile is formed as a thick-walled structural channel open to the panel side. The pultruded panel is thereafter cut to lengths equal to the desired height of a door panel.
