Galfan® is used as a coating on steel products requiring higher ductility/formability, with the same galvanic and physical barrier protection as galvanized products. This alloy is often used as a coating for wire or tube products. Eastern Alloys can also produces several variations of Galfan® with higher aluminum content, which are used to help maintain and adjust the bath chemistry or used in lines that are using a double dip process.
