Pultrusion is a mechanical process of pulling resin-saturated fibers though a heated die.

Our one-piece polymer composite fiberglass door panel produced by our proprietary technology is free of side seams, metal fasteners or 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.

Our door panels have a fully pultruded shell encapsulating a non-corrosive and insulating core.

Unlike conventional fiberglass doors, our proprietary technology produces monolithic FRP door panels using polymers selected for their immunity to corrosive environments, UV stabilized resin and a reinforced content of 65% by weight.

Our unique machining process produces a 'homogenized' fiberglass door slab with NO seams which does NOT rely on gelcoat (as do 'hand laid' form-built FRP doors). This means that our door panels CANNOT delaminate, craze or fuz.

Additionally, our fiberglass doors contain NO corrosive material (ie: aluminum or steel) in their framing or embedded as hardware or full mortised hinge installation reinforcement. This means our doors simply cannot degrade from the inside>out.

It also means greater non-conductivity and greater resistance to every known degrading environmental factor. So why put up with that problem door any longer? Make sure every door in your new or retrofitted facility does what doors are supposed to do.

Specific product formulations and manufacturing parameters are confidential since our competitiveness in today’s marketplace depends on our ability to produce products which have unique physical characteristics such as strength, durability, toughness, resistance to abrasive or corrosive forces and flexibility.
