Safety/Danger of Grinding Galvanized Metal

Safety/Danger of Grinding Galvanized Metal

Zinc melts at about 790 176;F and boils to vapor at about 1650 176;F. Therefore zinc oxide vapor can absolutely be created by grinding galvanized steel without quot;meltingquot; the base metal in a welding operation or otherwise. The likelihood of producing the zinc vapor in significant quantities goes up with reduced thickness of the workpiece.
