Abstract

Provided is a hot- dip galvanized steel sheet which not only exhibits excellent adhesion of a deposit even after press working but also ensures excellent post- coating corrosion resistance even after press working and which has excellent surface appearance. According to the present invention , the structure of a zinc deposit is controlled , said zinc deposit being formed by hot- dip galvanizing, while an intermetallic compound with prescribed characteristics is formed at a deposit/steel sheet interface. Further, the solidification structure of the deposit and the surface texture thereof are controlled. Specifically , the amount of Al in the deposit is adjusted to 0.3 to 0.6% by mass. Further, the amount of Al in the intermetallic compound is adjusted to 0.12 to 0.22gm*2, and the mean particle diameter of the intermetallic compound is adjusted to 1µm or less ,while the composition of the intermetallic compound is FeAl5 and/or FeAl3.
