Dec 06, 2017 · By the 1960s, galvanized steel had replaced lead as the building block of choice for plumbing. Steel pipes are galvanized when they are dipped into molten zinc. This zinc coating helps prevent rust. However, after decades of use, corrosion and rust build up on the inside of these pipes, which can cause problems. Galvanized Steel Pipe Uncoated Steel Pipe Coated Steel Galvanized steel pipe is most commonly used in plumbing and other water-supply applications. Black steel pipe features an all-over black finish. It is commonly used in fire sprinkler systems thanks to its high heat resistance. Black steel pipe is also popular for other water transfer applications, including potable water, as well as in gas lines.
