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 and makes it suitable for a wide range of applications. GI coils are commonly used in construction, automotive manufacturing, appliance production, and many other industries. The zinc coating acts as a sacrificial anode, corroding first to prevent the underlying steel from rusting. This makes GI coils a cost - effective and reliable choice for various projects.
