What is the difference between galvanized steel and carbon steel?
Galvanizing is a way to protect carbon steel without completely changing its structure. When carbon steel is galvanized, a layer of zinc is spread over its surface. Zinc is much lower on the galvanic scale than carbon steel, which means it's more basic and more likely to give up its electrons than carbon steel.
