The frame of FlexScreen has a core made of phosphate enhanced high carbon oil tempered spring steel, which is the same material as garage door springs or the leaf springs on your car. The frame is sprayed with an exterior grade high-performance duralloy PVC coating, which is the same material on a green park bench or a dishwasher rack. The frame goes through 4000+ hours of salt spray testing, proving it can withstand the elements of even the most tumultuous of climates.
