Zusammenfassung:	PURPOSE:To improve the chemical treatability of the plated surface of a steel sheet when the steel sheet is subjected to Zn alloy electroplating in plural plating vessels filled with plating baths having the same compsn., by specifying coating weight in the final plating vessel. CONSTITUTION:When a steel sheet is continuously subjected to Zn alloy electroplating in plural plating vessels filled with plating baths having the same compsn., coating weight in the final plating vessel is limited to
