Correct option is B
Galvanized iron (GI) is iron or steel coated with a protective layer of zinc to prevent rusting and corrosion. The zinc coating acts as a barrier, protecting the base metal from moisture and oxygen, which are the primary causes of corrosion. This process is commonly achieved through hot-dip galvanizing or electro-galvanizing.
Applications:
· Roofing sheets.
· Fencing and structural components.
· Water pipes and outdoor construction materials.
Advantages of Galvanized Iron:
· High corrosion resistance.
· Long-lasting protection in various environmental conditions.
· Cost-effective compared to stainless steel.
