Industrial Doors for the Harshest Environments

Along with our high-quality, commercial-grade doors, Lappen Security offers a line of specialty security doors manufactured to perform in the harshest and most-demanding of environments, including industrial facilities, pulp and paper mills, wastewater facilities, food processing plants and more.

High-Density (6lb./cu. Ft.) closed-cell polyurethane foam core reduces the weight of the door without diminishing its strength
Excellent thermal performance
Multiple layers of fiberglass reinforcing fabrics
Reinforcement Rail is 6" deep with 1/4" thick walls, providing for ample closer attachment
Two-Coat Polyurethane Industrial High Gloss Coating finish
FDA- and USDA-Compliant Coating provides excellent chemical, stain and abrasion resistance
Available in 10 standard colors, custom colors, or primer-only options
Fiberglass cannot corrode, rot or rust, making these doors ideal for corrosive environments
All standard industry hardware can be used with our FRP doors
