A steel sheet with two or more coatings and a method of producing the same are disclosed. The steel sheet has on at least one side a discontinuous surface layer of an Fe or Fe-Zn base alloy, preferably an Fe-Zn base alloy electrodeposit containing Sn in an amount of 0.01 to 50 mg/m2, usually in an amount of 1.0 to 50 mg/m2, preferably in an amount of 3.0 to 30 mg/m2, and also 5 to 50% by weight of Zn in case Fe-Zn alloy is used, and a layer of Zn-Ni or Zn-Fe alloy electrodeposit, which lies directly under said discontinuous surface layer. |
