Zusammenfassung:	PURPOSE:To easily obtain a Zn - high Al alloy plated steel sheet free from cracks in a plating layer on a working part and excellent in workability by means of a continuous line by applying Zn - high Al alloy plating to a steel sheet, blasting a plated surface, and then subjecting this plated steel sheet to heat treatment at a low temp. for a short time. CONSTITUTION:Zn - high Al alloy plating is applied to a steel sheet and blasting treatment is applied to the resulting plated surface, and successively, this plated steel sheet is subjected to heat treatment at a low temp. for a short time. Further, it is desirable to perform the above heat treatment under the conditions of about 150-270 deg.C and
