DOOR COMPONENTS BY GREENLAND COMPOSITES Greenland Composites manufactures high quality exterior residential door parts. Our recycled wood/plastic composite materials have become the solution for rot and decay in steel and fiberglass exterior doors. Bottom and top door rails comprised of our composites have become the standard for major manufacturers of doors nation-wide. The benefits of wood plastic composites compared to wood, pvc, mdf, and other materials are significant. Dimensional stability: Eliminates twist, knots, and bonds permanently to steel and fiberglass door skin Resistance to rot & decay: Vast improvement in expected service life of exterior residential doors Moisture abatement: Water & moisture is prevented from entering doors thus eliminating structural deterioration Cost effectiveness: Proven cost reductions and price stability versus wood and other rail materials Sustainable resource: Forests are preserved and recycled / recovered PE and Wood fiber are utilized Environmentally sound: No hazardous materials or voc's in our formulations Resource utilization: Excellent use of recycled and recovered raw materials from U.S. landfills and waste stream Made in the U.S.A.: American Manufacturer, American Labor, and American Raw Materials
