Steel is an alloy made primarily of iron and carbon, with small amounts of other elements. Zinc, on the other hand, is a chemical element, not an alloy. It is a metal with the atomic number 30 and is commonly used as a coating to protect other metals from corrosion through a process called galvanization. Galvanized steel, for example, is steel coated with a layer of zinc to prevent rusting and improve its durability. Zinc is also used in various other applications, including batteries, alloys, and as a dietary supplement.
