Introduction to GI Sheet
Galvanized iron (GI) sheet is a type of steel sheet 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 sheets are widely used in construction, automotive manufacturing, household appliances, and many other industries due to their durability, affordability, and versatility. The zinc coating acts as a sacrificial anode, corroding first to protect the underlying steel. This makes GI sheets highly resistant to rust and other forms of environmental damage, even in harsh conditions.
