Hot Dip Coated Steel Sheet

Abstract: The present invention employs a hot dip-coated steel sheet that comprises a hot dip-coated layer formed on a surface of a steel sheet. A pattern section and a non-pattern section are formed in the hot dip-coated layer. The pattern and non-pattern sections include a first region and a second region defined in the following, and the absolute value of the difference in the area percentage of the first region between the pattern and non-pattern sections is at least 30%. A cross-section parallel to the surface of the hot dip-coated layer and located at either one of positions of 3t/4, t/2, and t/4 from the surface is exposed. Then, virtual grid lines are drawn on each cross-section to divide the cross-section into a plurality of regions. A region, in which the ratio of the area fraction B of a [Zn phase] with respect to the total area fraction A of the [Zn phase] and a [ternary eutectic structure of Al/MgZn2/Zn] is at least 20%, is defined as the first region, and a region, in which said ratio is less than 20%, is defined as the second region.
