Frequently Asked Questions | American Tinning & Galvanizing - Erie, PA

The molten zinc is applied at 830 to 850 degrees; the zinc will bond with the steel. It is the most common outdoor protective coating in use. Galvanizing is a favored because of its long maintenance-free service life. Zinc plating or electroplating is a process where zinc is applied by using a current of electricity. It is a thinner coating than hot dip galvanizing.
