Zinc(zn) is higher than iron(fe) in d electrochemical series, so it used to coat it, unlike d oda options dat ar lower in d series.

NOTE THAT GALVANIZATION HAS TO DO WITH ZINC.... SPECIFICALLY
LIKE ONLY ZINC CAN BE USED TO COAT OR GALVANIZED IRON OR STEEL

BUT TALKING OF ELECTROPLATING, IT'S BROAD, ANY ONE CAN BE USED, DEPENDING ON WHAT YOU WANT TO GET...

NOTE THAT GALVANIZATION IS ONE OF THE TYPE OF ELECTROPLATING THAT SPECIFICALLY DOES WITH ZN.
