Abstract
A method for finishing molten metallic coatings applied to iron and steel strip by the use of an elongate, laminar flow fluid jet, which jet is used to control thickness and quality of the finished coating. The narrow dimension of the fluid jet is contoured across the strip width to produce the desired coating weight at all parts of the strip and to produce a coated strip edge free from excessively heavy coatings and/or oxide 'berries.'
