This process ensures that an even layer of zinc or zinc alloy covers the steel, and allows for the creation of different grades of zinc coating, as the zinc or alloy can be applied in a thick layer for heavy-duty galvanization. GALVANIZED SHEETING: Stock Description. Electrolytic galvanization does not create as thick or heavy of a protective zinc layer as hot-dipping, and is therefore usually reserved for steel which will not see extensive outdoor exposure. Nuts, bolts, tools, and wires of all kinds are now galvanized because it is a cheap process, and helps boost the metal’s lifespan!
