G.I. (Galvanized Iron) pipes and fittings are widely used in plumbing and construction due to their durability and resistance to corrosion. Galvanization involves coating iron or steel with a layer of zinc, which helps protect the metal from rust and extends its lifespan. These pipes are commonly employed for water supply, drainage, and various industrial applications. Their threaded fittings allow for easy assembly and disassembly, making them a practical choice for both permanent installations and temporary setups. Overall, G.I. pipes and fittings provide a reliable solution for transporting fluids in various environments.
