Abstract
A method for coating a moving steel strip with a metal or metal alloy coating, wherein the steel strip runs through a bath of molten metal or metal alloy to coat the steel strip, and the coated steel strip is wiped to control the thickness of the coating using foils or sheets. The bath of molten metal has a volume at most 10,000 times the volume V of the coating on the steel strip per second, volume V in m3 being given by the formula V=2×d×w×s, wherein d=the thickness of the coating in meters, w=the width of the strip in meters, and s=the velocity of the strip in meters per second.
