Hot-dip galvanized steel sheet is excellent in adhesion with a hot-dip galvanized zinc layer, and has high tensile strength and good formability even when a steel sheet containing Si and Mn in relatively larger amounts is used as a basis steel sheet. The hot-dip galvanized steel sheet is composed of: a basis steel sheet containing Si in an amount of 0.05 to 2.5% and Mn in an amount of 0.2 to 3%, by mass; a Fe plated layer formed on the basis steel sheet; and a hot-dip galvanized zinc layer formed on the surface layer of the basis steel sheet via the Fe plated layer, wherein oxides containing Si and/or Mn are discontinuously dispersed in the vicinity of the interface between the basis steel sheet and the Fe plated layer.

PPGI/PPGL(color coated steel or prepainted steel coil) is a kind of steel plate with organic coating. Color steel plate is divided into single board, color steel composite board, floor board and so on. Widely used in large public buildings, public factories, movable board houses, and integrated house walls and roofs.
