Introduction to GI Coil
Galvanized iron (GI) coil is a type of steel coil that has been coated with a layer of zinc to protect it from corrosion. This process, known as galvanization, significantly extends the lifespan of the steel, making GI coils a popular choice in various industries. The zinc coating acts as a sacrificial anode, corroding first to prevent the underlying steel from rusting. GI coils are widely used in construction for roofing, wall cladding, and structural components, as well as in the manufacturing of appliances, automotive parts, and electrical enclosures. Their durability, cost - effectiveness, and versatility have made them an essential material in modern industrial applications.
