Galvanizing is the process of applying a zinc coating to iron and steel to prevent corrosion. Hot-dip galvanizing, electrogalvanizing, and zinc spraying are three of the most used methods for adding zinc to iron and steel. The continuous sheet hot-dip technique is used to coat the majority of galvanized products Jet wiping is a process of hot-dip galvanization and is used to regulate the thickness of a liquid coat on a moving substrate by wiping the free surface. Nevertheless, some undulation phenomena occur over the zinc film due to the jet wiping action; among different actuators used to cope with this issue, the electromagnetic (EM) control system seems a viable solution.
