The invention relates to a method for finishing a hot-dip coated steel sheet, comprising the step of rolling a hot-dip coated steel sheet by using a finishing roller, wherein the surface roughness of the finishing roller Ra is less than or equal to 1 Mum. The method is especially suitable for hot galvanized steel sheets and hot galvanized and aluminized steel sheets with zinc spangles on the coated surface. The method can ensure good shape, surface quality and coating performance of the hot-dip coated steel sheet and can ensure that zinc spangle profiles on the coating surface are clear and maintain good appearance decoration performance. In addition, the method is also suitable for finishing hot galvanized and aluminized steel sheets and facilitates the application of the hot galvanized and aluminized steel sheets to the electric appliance manufacturing industry and other industries having higher requirements for shape, surface quality and coating performance of the hot galvanized and aluminized steel sheets.
