Introduction to GI Steel Coil
Galvanized iron (GI) steel coil is a type of steel 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 steel coils are commonly used in construction, automotive manufacturing, household appliances, and various industrial sectors. The zinc coating not only provides excellent corrosion resistance but also enhances the aesthetic appeal of the steel.
