Abstract

The problem addressed by the present invention is to provide a method for producing, on a continuous hot-dip galvanizing line, a hot-dip Al-Zn alloy coated steel sheet having outstanding corrosion resistance in the flat part and excellent corrosion resistance in worked parts by virtue of good workability, and a hot-dip Al-Zn alloy coated steel sheet obtained using said method. In order to address the aforementioned problem, the present invention is characterized in that the steel sheet after hot-dip galvanization is maintained for 5-60 seconds at a temperature of 250-375°C in a continuous hot-dip galvanizing facility.
