PURPOSE:To reduce man-hour for production and to reduce working time and line by coiling a steel wire drawn to an irregular-shaped steel wire and subjecting the coiled wire to electrogalvanizing after cutting then subjecting the cut wire to a heat treatment and baking treatment. CONSTITUTION:A hard steel wire is drawn to a rectangular shape, is coiled and is cut and thereafter the cut wire is electrogalvanized. The wire is then subjected to a heat treatment and baking treatment, by which work strain and penetrated hydrogen are removed. If the wire is treated at and for an adequate temp. and time, the wire is accepted in the requirements specified in JIS which spacifies the hardness and the height after compression. The conventional stages in which the heat treatment and baking are performed before and after the electrogalvanizing are combined to one time, by which the man-hour is reduced and the working time and line are made shorter.
