Galvanised Plain Sheets

Flat mild steel sheets with a coating of zinc to stop corrosion and rust are known as galvanized plain (GP) sheets. They are frequently utilized in commercial, residential, & industrial projects and are commonly known as plain GI sheets. Although they are less resistant to corrosion than pre-painted alternatives, GP sheets, which are renowned for their strength, durability, and long-lasting performance, provide dependable protection.
