M. S. plates are available in different finishes, including hot-rolled, cold-rolled, and galvanized. Hot-rolled M. S. plates have a rough surface texture and are commonly used for structural applications, while cold-rolled M. S. plates have a smoother surface finish and are preferred for precision and aesthetic applications. Galvanized M. S. plates are coated with a layer of zinc for enhanced corrosion resistance, making them suitable for outdoor use and corrosive environments.
