The steel base metal gets red hot on occasion locally (right at the grinding or cutting wheel) meaning it is 1600-1800 °F. 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.
