ABSTRACT:
When a hot-dip zinc plating layer, which contains Al, is applied on rimmed steel having an Si level of less than 0.05% by weight or less, by the two-stage plating method, appearance failure can be prevented by setting the plating conditions as follows: in a first zinc bath consisting of zinc of 99.7% purity or more or in a second zinc bath which consists of zinc with 99.7% purity by weight or more and 0.05% or less of Al at a temperature of from more than 460.degree. C. to 490.degree. C. and for a dipping time of from 1 minute to 1.5 minutes; and, in a second zinc bath consisting of zinc of 99.7% purity by weight and from 2 to 10% by weight or less of Al at a temperature of from 400.degree. C. to less than 430.degree. C. and for a dipping time of from 0.5 minute to 1.5 minutes. This plating condition provides a plating structure that the Zn, Fe and Al are present in the essentially entire portion of the plating layer. The Zn-centration increases in the direction from the boundary to the top of said layer; the Al concentration decreases in the direction from the boundary to the top of said layer.
