Abstract
PURPOSE:To produce a Zn alloy plated steel sheet having superior corrosion resistance, chemical treatability and adhesion to paint by galvanizing a steel sheet with a galvanizing bath having a specified Pb concn. and by electroplating the galvanized steel sheet by a specified amt. with a Zn alloy plating bath having a specified Pb concn. CONSTITUTION:When a Zn alloy plated steel sheet is produced, a steel sheet is galvanized with a galvanizing bath having 0-1ppm Pb<++> concn. to form a first layer (lower layer). The galvanized steel sheet is electroplated by >=0.1g/m<2> with a Zn alloy plating bath having >=1ppm Pb<++> concn. to form a second layer (upper layer). Thus, a Zn alloy plated steel sheet useful as a rustproof steel sheet for an automobile body or household electrical appliances or as building materials is obtd.
