Abstract
A plated steel material includes a plated layer containing, by wt %: 0.5 to 14% of Al, 0.5 to 5% of Mg, and the balance being Zn and inevitable impurities. The plated steel material satisfies the following Equation: ([Mg]−[Mg])/[Mg]≥0.3. [Mg]means a content (wt %) of Mg in a surface of the plated layer, and [Mg]means a content (wt %) of Mg at a ½t position (t represents a thickness of the plated layer) from the surface of the plated layer in a thickness direction.
