Abstract: The zinc-base plated steel sheet has a steel sheet, a zinc-base plating layer on the steel sheet, and a composite coating film formed on the plating layer, which composite coating layer contains a P ingredient, an N ingredient, and at least one element selected from the group consisting of Mg, Al, Ca, Ti, Fe, Co, Ni, Cu, and Mo, and is prepared by applying an aqueous solution containing a cationic ingredient (?) and a phosphoric acid ingredient (?) onto the surface of plating layer on the zinc-base plated steel sheet, and then drying the applied aqueous solution, without giving washing with water, and which cationic ingredient (?) consists essentially of at least one metallic ion selected from the group consisting of Mg, Al, Ca, Ti, Fe, Co, Ni, Cu, Mo, and NH4+ ions.

Abstract: The method for manufacturing galvanized steel sheet has a step of adjusting the surface texture thereof by blasting solid particles against the surface thereof. The surface texture is defined by at least one parameter selected from the group of parameters consisting of mean roughness Ra on the surface of steel sheet, peak count PPI on the surface of steel sheet, and filtered centerline waviness Wca on the surface of steel sheet. The galvanized steel sheet has a surface in dimple-pattern texture.
