PROBLEM TO BE SOLVED: To provide a steel strip having a corrosion-resistant alloy coating, having remarkably enhanced corrosion resistance of a coating and remarkably improved coating ductility, usable at a high cooling rate, and capable of shortening the length of a required cooling device.SOLUTION: There is provided an Al-Zn-Si-Mg alloy-coated strip having MgSi particles in a coating fine structure. The distribution of the MgSi particles is a distribution having only a small amount of MgSi particles or not having substantially MgSi particles at a surface region of a coating. |
