Abstract

A method and apparatus for treating a freshly metallized substrate in which a metal substrate is passed through a bath of molten metal for the purpose of applying a coating thereto while a treating gas containing a reducing gas, a non-oxidizing gas or combination thereof is provided at the region where the metallized substrate exits the molten metal bath to thereby at least reduce oxidation of the metallized substrate and the surface of the molten metal bath.
