The unique construction of Tiger Door's standard, non-fire-rated FRP door combines a beautiful, yet tough exterior surface with an aerospace-inspired honeycomb core construction, assembled by exclusive press-molded technology.

The Tiger Door core starts with a high-modulus, pultruded FRP tubular backbone. This structural stile and rail sub-frame provides a large portion of the door's tremendous endurance. At the corner joints and hardware locations of the sub-frame, non-hygroscopic one-piece blocks – molded from high density foam polyurethane – are inserted to provide the ultimate in corner strength. The cavities between the FRP sub-frame are then filled completely with a phenolic impregnated honeycomb.

The skins of the door begin with the application of an “in-mold” tough satin textured color gel coat. Chopped strand glass-fiber mat forms the connective tissue, followed by a muscular knitted 3-layer oriented strand glass fiber structural reinforcement. The multi-directional reinforcing further enhances the great strength of the door.

Finally, the skins are simultaneously fused onto both faces and all edges of the door under heat and pressure until cured – not only to the FRP sub-frame but to the entire honeycomb core as well.

The result of this process is a lightweight, extremely high corrosion-resistant, factory prefinished door assembly that carries a lifetime warranty. It is important to note that Tiger Door products contain no ferrous metal or wood components in their construction that could lead to premature failure.

Because of this construction, no other wood, steel, aluminum, or composite product offers the combination of strength, beauty and endurance embodied in a Tiger Door – the first choice in FRP doors.

Regardless of the specifications, Tiger Door engineers can design custom doors to meet the most demanding requirements. Special sizes and configurations are available. Contact us with your specific project requirements.
