Abstract: Provided is a hot dip zinc (Zn) alloy plated steel sheet having excellent corrosion resistance and surface qualities, and a method of manufacturing the same. For this purpose, provided is a high corrosion resistant hot dip Zn alloy plated steel sheet which includes an underlying steel sheet and a hot dip Zn alloy plating layer, wherein a composition of the hot dip Zn alloy plating layer includes 1 to 3 wt % of aluminum (Al), 1.5 to 4.0 wt % of magnesium (Mg), and Zn and unavoidable impurities as a remainder, in which Al+Mg is in a range of 2.5 to 7.0 wt % and Al: (Al+Mg) ratio is in a range of 0.38 to 0.48, and a method of manufacturing the high corrosion resistant hot dip Zn alloy plated steel sheet.

Abstract: There is provided a hot-dip Al—Zn coated steel sheet that has a steel sheet containing Si and Mn as a base steel sheet and has excellent coating appearance and corrosion resistance. The Al—Zn coating layer has an Al content in the range of 20% to 95% by mass. The Al—Zn coating layer has a Ca content in the range of 0.01% to 10% by mass. Alternatively, the Ca and Mg content is in the range of 0.01% to 10% by mass. A steel sheet surface layer within 100 ?m from a surface of the base steel sheet directly under the Al—Zn coating layer contains less than 0.060 g/m2 per surface of an oxide of at least one selected from Fe, Si, Mn, Al, P, B, Nb, Ti, Cr, Mo, Cu, and Ni in total.
