Abstract

Provided is a Zn—A—Mg coated steel sheet having a plated layer including from 4 to 22% by mass of Al, from 1.0 to 6.5% by mass of Mg, from 0.001 to 1.000% by mass of Si, as well as Zn and impurities as the balance, wherein the structure of the plated layer contains an Al primary crystal, the Al primary crystal including: a cellular dendrite-shaped first Al primary crystal and a second axis spacing of from 0.5 to 2.0 μm; a minute equi-axed dendrite-shaped second Al primary crystal and a second axis spacing of from 0.5 to 2.0 μm; and a petal-shaped third Al primary crystal with a principal axis length of from 0.5 to 3.0 μm and a ternary eutectic structure of Al, Zn, and MgZnas a structure other than the Al primary crystal.
