Abstract

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