Galvanized sheets are steel or iron sheets coated with a layer of zinc to prevent rusting and corrosion. The galvanization process involves hot-dip coating or electro-galvanizing techniques. These sheets are widely used in construction, automotive, and appliance industries due to their durability and corrosion resistance. The zinc coating also provides sacrificial protection, meaning it corrodes instead of the underlying metal. Galvanized sheets are valued for their longevity and low maintenance.
