Hot Sale Hot Dipped Galvanized Steel Pipe Q235B 1.5mm Gi Steel Pipe For Scaffolding
Galvanized pipe is made by coating steel or iron pipes with a protective layer of zinc, which helps prevent corrosion. This pipe is a type of metal pipe.
Before World War II, lead pipes were used for drinking water in plumbing systems, but it was later realized that lead pipes were a huge threat to health, which required some other new material to replace lead pipes. Iron and steel are prone to corrosion over time, although they were perfectly good options.
They were coated with zinc to protect against corrosion, and those pipes began to be used in plumbing pipes instead of lead.
Galvanized steel pipes were a popular choice for indoor plumbing in many homes built before the 1960s. These pipes are nearing the end of their life cycle for many homeowners, as their lifespan is around 20 to 80 years.
Since the mid-1940s, copper and plastic piping have become the preferred material, although industrial projects and steel reinforcement are needed, whereas galvanized pipes are still preferred for outdoor buildings.
