  • Patent number: 5775041
    Abstract: Durable, high strength entry systems and methods for their manufacture are provided. The entry systems are formed by assembling profiles produced by extruding and then machining and/or molding a composite material. The profiles are formed in a preferred embodiment by extruding a cellulose composite material to produce an extrusion which preferably contains hollow sections which reduce the weight and cost of the material. The extruded composite can be machined and/or molded after the extrusion process to provide means for securing the profiles to each other or to glass and panel inserts. Entry systems, such as sidelights, transoms and exterior doors, can be produced from the assembled profiles which are durable and strong and therefore resist corrosion, denting and decay. The entry systems can be produced from low cost wood substitutes and provide the appearance of real wood. The entry systems can be readily treated with paint or other finishing materials to provide the desired exterior finish.
