Actually zinc is used in many ways (in tires, in brass) but the main use is in protecting steel against corrosion - galvanising. In this application it is applied as a surface coating (electrolytically or hot dip). The idea is that zinc provides a protective layer, and also being more electropositive than iron it will be preferentially corroded if steel is exposed. As far as I know stainless steel doesn't have any zinc in it. From what I've read there is currently no good substitute for zinc in galvanising. Most steel that is exposed to the weather will have zinc on it, then maybe paint. Car bodies, for example, are zinc coated before painting. galvanizeit.org Industrialisation seems to inevitably lead to a big increase in zinc consumption. All that construction going on in China is sucking up a lot of zinc.
