The Pultrusion Method
Our doors are manufactured by a machine process that pulls resin-saturated glass fibers continuously through a heated die forming a monolithic polymer bond around a urethane foam core.
Our one-piece pultruded polymer door panel produced by our proprietary technology is free of side seams, metal fasteners and metal reinforcing plates. Since there are no side seams delamination is impossible.
Top cap and bottom cap are FRP profiles, chemically welded to the panel structure and fully sealed. Surface skins are 1/8" thick and consist of a combination of continuous strand and knit mat.
Integral stiles are 9/16" thick solid pultruded fiberglass along both sides the entire length of the panel making it possible to prep for butt hinges or a continuous hinge at any location along the stile.
Unlike conventional fiberglass doors, our proprietary technology produces FRP door panels using polyester resin selected for their extreme resistance to corrosive environments, combine this with a fiberglass content of 65% by weight. What you get is the strongest FRP Door System on the market.
Our "pultrusion" process produces a Monolithic fiberglass door slab with NO seams. This means that our door panels CANNOT delaminate, craze or fuz. Additionally, our fiberglass doors contain NO corrosive material (ie: aluminum, wood or steel) in the core or structure frame work. This means our doors simply cannot degrade from the inside out.
