Final answer:
The stainless steel or aluminum coating process with hot-dipped zinc is referred to as galvanization, an electrochemical method for corrosion prevention.
Step-by-step explanation:
The process by which stainless steel or aluminum is coated with hot-dipped zinc is called galvanization. Galvanization is an electrochemical process used to prevent the corrosion of metals. By applying a thin layer of zinc, the steel or aluminum is offered prophylactic protection from oxygen in the air and also serves as cathodic protection. When exposed, the zinc will oxidize before the underlying metal.
