The process that forms it on them is called zinc plating The process can differ depending upon the metal finishing company’s preferences and the zinc plating application available Generally it starts by cleaning the metal’s surface using an alkaline detergent solution in order to

This process allows the zinc to permanently bond to the metal not only on the surface but within the steel itself making a secure and complete bond Other methods include continuous sheet galvanizing painting or spraying on the zinc and electroplating Using processing such as galvanization can be incredibly beneficial to the steel

Material adapted from Hudson TL Fox FD and Plumlee GS 1999 Metal Mining and the Environment p 7202731353839 Published by the American Geosciences Institute Environmental Awareness Series Modern mining operations actively strive to mitigate potential environmental consequences of extracting metals and such operations are strictly regulated in the United
