Abstract
A plated steel wire, according to one aspect of the present invention, comprises: a base steel wire; and a zinc alloy plated layer. The zinc alloy plated layer comprises, in percentage by weight: 1.0% to 3.0% of Al; 1.0% to 2.0% of Mg; 0.5% to 5.0% of Fe; and the balance being Zn and unavoidable impurities, and includes a Zn/MgZn2/Al ternary eutectic structure, a Zn single-phase structure, and an Fe—Zn—Al-based crystal structure, wherein the Fe—Zn—Al-based crystal structure is formed adjacent to the base steel wire, and can have an average thickness of ⅕ to ½ with respect to an average thickness of the zinc alloy plated layer.
