GALVALUME sheet steel is a 55% Al-Zn coated sheet steel product that is ideally suited for most types of roofing and siding applications as well as unexposed automotive parts, appliances and miscellaneous applications like furniture, outdoor cabinetry, computer cases, gutters, pipe, etc. These pans are a heavy duty 26 guage Pre-Coat pre-painted steel produced from substrates of Hot Dipped Galvanized steel that are painted in coil form with protective, baked on paint coatings. This is an extremely durable paint system that is tested to stand up to many years of external use and abuse from the elements which makes it a good for use in chew proof trays for pet cages. The baked on painted coating is highly scratch resistant and does not chip and is very easy to clean. Even if the paint does get scratched, having a Hot Dipped Galvanized coating below the painted surface protects the metal from rusting.
