Galvanized steel items are first dipped in acid to remove oxides and then
into molten zinc. The zinc bonds to the surface of the steel much like
solder sticks to a copper wire. Hot dipped galvanizing is a heavier coating
than you would see on an electropated zinc product. The wall literature we
have from a galvanizing shop in our area predicts a life of up to fifty
years.
