More ...Pipe galvanizing is a coating process that gives steel pipe a zinc coating to prevent corrosion and rust. Pipe galvanizing was widely used in residences constructed. When it was introduced, galvanized pipe was an alternative to lead pipe for water supply lines.

Features of Hot Galvanized Steel Pipe
Without pipe galvanizing, corrosion is a persistent danger to metal; therefore, it must be protected. It is possible to create oxidation in metal when corrosive elements such as salt, dirt, moisture, or chemicals come into contact with the iron in the metal. Rust is formed as a consequence of the reaction. Because of the corrosion of metal, pipes are at risk of collapsing or exploding.
Adding a coating of zinc to metal during the pipe galvanizing process serves to protect it against corrosion.
