Reply to comment by LameTrouT in How come some Galvanized steel panel have patterns? by LameTrouT

The patterns on the surface of galvanized steel are called 'spangle'. People who use galv steel order spangle size. Antimony is used in the molten zinc bath for spangle size control among other process controls. Metallurgist here.
