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 it suitable for a wide range of applications. GI coils are commonly used in the construction industry for roofing, wall cladding, and structural components. They are also utilized in manufacturing household appliances, automotive parts, and various metal products. The zinc coating provides a sacrificial layer that corrodes preferentially, safeguarding the underlying steel from rust and deterioration. The demand for GI coils is increasing due to their durability, cost - effectiveness, and versatility.
