Abstract
An inventive method may perform a plating the surface of the metals sheet without using a molten plating metal. This method successively melts a supplied solidus plating metal in close proximity of the passing metal sheet and adheres the molten plating metal as a plating film to the surface of the metal sheet, where the metal sheet passes upwardly and the plating metal is supplied through an upwardly-directed nozzle disposed near the passing sheet, and when or immediately before the plating metal is supplied from the nozzle, it is molten by a heat melting means. The molten plating metal forms a pool at a corner defined between the surface of the passing sheet and the tip of the nozzle, and the molten metal of the pool forms a plating adheres to the sheet surface and forms the plating film.
