Providing Overhead Screen Doors and Ventilating Dock Doors for Your Facility Rasco Industries, Inc. was incorporated in 1992 with a product mission to provide high quality, overhead screen doors for food processing plants, distribution warehouses, manufacturing plants, and other facilities that had a requirement to use their loading dock door for ventilation while keeping out insects, birds and other pests. We worked closely with the American Baking Institute???s (AIB) food facility inspection group in Manhattan, Kansas and the U.S.D.A laboratory in Madison, Wisconsin to develop an industrial screen door that would meet the inspection, pest control and cleaning practices of food related facilities by acting as a bird, rodent and bug screen.
