Why does zinc not rust?

The zinc layer acts as a sacrificial metal for the steel. This means that the zinc layer will combine with the oxygen more readily than the iron in the steel will. This creates a zinc oxide layer that prevents the formation of iron oxide, thus eliminating the possibility of rust forming.
