Abstract

Provided are a zinc alloy plated steel and a method for manufacturing same, the zinc alloy plated steel comprising: a base iron; a Zn plated layer formed on top of the base iron; and a Zn—Mg alloy layer formed on top of the Zn plated layer and obtained through mutual diffusion of Zn and Mg, wherein the ratio of the weight of Mg contained in the Zn—Mg alloy layer with respect to the total weight of the Zn plated layer and the Zn—Mg alloy layer is 0.13 to 0.24, and the sum of the adhesion quantity of the Zn layer and the Zn—Mg alloy layer is no more than 40 g/m(more than 0 g/m).
