A GI (Galvanized Iron) pipe is a steel pipe coated with a layer of zinc to prevent corrosion. It’s commonly used for water supply, gas, and drainage systems. GI fittings are connectors, elbows, tees, and other components made from galvanized iron. These fittings are used to join and redirect GI pipes, ensuring a leak-resistant and durable connection. They are widely employed in plumbing and industrial applications due to their rust-resistant nature and ease of installation.
