Hot Dipped Galvanized Steel Coils: What You Should Know
Hot dipped galvanized steel coils are steel coils that have been zinc-coated using the hot dipped galvanizing process. Steel coils are immersed in a molten zinc bath, which establishes a metallurgical bond with the steel substrate. This results in a protective zinc coating that helps prevent corrosion and increases the steels lifespan.
