Galvanized Steel Pipes
Galvanized steel pipe is a metal tube that has been galvanized to prevent corrosion. It’s commonly used to transport water and wastewater but galvanized steel pipe also has many other uses. The process of galvanization involves dipping a steel pipe into a protective zinc coating to prevent corrosion (also known as zincification). Galvanized piping was commonly installed in homes built before 1960.
What galvanized pipes are used for:
In plumbing, galvanized steel pipe is often used as a drainage material — either above ground or below ground. In homes, galvanized steel piping can be found in both heating and cooling systems. And galvanized supply lines connect homes with city water supplies (where the zinc coating helps protect against lead contamination). If your steel pipes are cracked, you might need to call a repiping plumber to replace the pipes.
