Abstract: A hot dip coating device to provide a metal coating on a moving metal sheet, containing a liquid bath of metal coating material in use. The metal coating material on the moving metal sheet in use, including a container for the liquid bath, a guide or sink roll in the container below liquid bath surface level in use to guide the moving metal sheet through the bath, and a gas knife, above the liquid bath in use, having an outlet to project wiping gas on the metal coating on the metal sheet. At least one supporting roll with the guide or sink roll in use influence metal sheet shape in its width direction at the gas knife location. The one supporting roll is above liquid bath surface level to operate on the metal sheet before the metal sheet enters the bath.

Abstract: A method for producing a steel substrate coated with a chromium metal-chromium oxide (Cr—CrOx) coating layer in a continuous high speed plating line, operating at a line speed (v1) of at least 100 m·min?1, wherein one or both sides of the electrically conductive substrate in the form of a strip, moving through the line, is coated with a chromium metal-chromium oxide (Cr—CrOx) coating layer from a single electrolyte by using a plating process. A coated steel substrate and a packaging made thereof.
