Galvanization Process - photo: http://www.tlirr.com/galvanizing[/caption]The term galvanized refers to metal, most often steel, that has been put through the process of galvanization. The word is derived from the name of the Italian scientist Luigi Galvani, who in 1772, discovered the electrochemical process that takes place between metals during an experiment with frog legs, but that's a whole other story.
As described in Wikipedia, Galvanization (or galvanisation) is the process of applying a protective zinc coating to steel or iron, in order to prevent rusting. Further reading at galvanizit.org shows that the first record of zinc use in construction dates back to the first century AD, but that it was in 1742 that P.J. Malouin, a French chemist, presented to the Royal Academy of Sciences several experiments involving coating iron with molten zinc.
