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 for galvanized steel pipe used greenhouse structure
