Heavy Duty Doors

The Tiger Heavy Duty Door Series starts with a core that consists of a 3/8" triangular cell phenolic-impregnated kraft honeycomb surrounded by a rigid high-modulus, pultruded FRP tubular structural stile, rail and midrail sub-frame. At each of the sealed corner joints and hardware locations of the sub-frame, non-hygroscopic polymer blocking is inserted as reinforcement, providing the ultimate in strength for screw retention and compression resistance.

The skins for the door begin with the application of an "in-mold" 25-30 mil gel coat. Then a chopped strand glass fiber mat is applied to form the connective tissue, followed by a muscular bi-axial glass fiber structural reinforcement layer that further strengthens the door skins.

Finally, the composite 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 - forming a bond that fully integrates all the components. This highly advanced method of assembly using press-mold technology is only available from Tiger Door. Each door is factory finished with a specially formulated multi-component polyurethane industrial chemical coating for the semi-gloss color topcoat.

The Tiger Heavy Duty Door Series comes with a limited lifetime warranty and provides excellent service life and corrosion resistance for the most severe environments.
