Frank Door Company's cold storage doors are wood free. We have provided our customers, U.S.D.A. inspectors, architects, designers and consultants wood free products for over a decade. Wood warps, rots, collects moisture and can harbor bacteria and other microbes like mildew, mold and fungus. To address these hygienic and safety concerns our sliding doors feature an internal aluminum structure coupled with steel corner brackets and mounting plates providing unprecedented strength and a hygienic wood-free door. Furthermore, our thermally insulated casings and headers are extruded from aluminum; providing durable sanitary door frames. High density polyethylene casings and headers are available on request.

Frank sliding doors are UL listed. With over 35 years of experience, Frank Door has acquired knowledge that allows us to provide our customers with the correct heat for their door. All doors are tested and inspected after wiring is complete for quality control and long heater wire life. Sliding doors have full perimeter heat in the door panel and heaters in the casings and headers. 230 volt heaters are available upon request.

Frank Door Company's DropTrac is constructed of heavy duty aircraft grade aluminum extrusions. Unique design advantages balance hygiene, style and performance in a package that can sustain years of use under the toughest conditions. Discover the DropTrac difference.
