Zinc melts at about 790 °F and boils to vapor at about 1650 °F. Therefore zinc oxide vapor can absolutely be created by grinding galvanized steel without "melting" 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.
