What Is Galvanization?

Galvanization or galvanizing is a process dating back to the early 19th century. Two men, one English, the other French, came up with this method of treating steel or iron. They invented a means through which they fought off the effects of corrosion by coating the material with zinc. Stanislas Sorel (1803-1871), a French engineer, 1837 filed a patent in 1937 for the rust protection for iron.

This process, now called galvanization, describes one of the several means through which the application of zinc provides a protective coating to the surface of the substrate or base metal.
