What is galvanized metal used for?
Uses for galvanized metals vary wildly, from large sheet metal pieces to small screws that are used in wood projects. Galvanized metal is a specially made material that provides added protection against corrosion and oxidation, characterized by an outer coating of zinc oxide. The zinc acts both as a physical barrier for the metal and as a chemical one. Since zinc is more reactive from an electrochemical perspective, it also acts as a sacrificial anode, meaning that it will draw all corrosive effects onto itself to spare the metal beneath.
