G60 Galvanized Sheet Steel

For example g60 is galvanized with a two side triple spot coating weight of at least 0 60 oz ft 2.

G60 galvanized sheet steel.

And galvanized designated with a g g40 g60. The size of the crystallites in the galvanized coating is called spangle and it will greatly alter the appearance of the galvanized sheets.
