GP (Galvanized Pipe) pipes are similar to GI (Galvanized Iron) pipes but can refer to a broader category including galvanized steel pipes. These pipes are coated with a layer of zinc to protect them from corrosion and rust. The galvanization process involves dipping the pipes into molten zinc, creating a protective barrier that enhances their durability and longevity. https://hitechpipes.in/galvanized-steel-pipes-gp-pipes-hi-tech-pipes
