Abstract: This invention relates to a method of simultaneously coating both sides of a moving strip with a solution, said strip having a pass line above the bath of said solution, comprising the steps of lifting a column of said solution out of said bath, said column being wider than said strip and higher than the pass line of said strip, passing said strip through said column of solution, and controlling the speed of said strip and the height and width of said column relative to the width of said strip and height of the strip pass line whereby both sides of said strip are coated simultaneously. The strip can be a galvanized strip treated with a chromate conversion coating or can be a tin plate treated with palm oil.
