Abstract
Provided is a method of producing a hot-dip metal coated steel strip with which a hot-dip metal coated steel strip of high quality can be produced by sufficiently suppressing edge overcoating. The method comprises spraying gas from a pair of gas wiping nozzlesA andB onto a steel strip S while being pulled up from a molten metal bathto adjust a coating weight of molten metal on both sides of the steel strip S, wherein a pair of baffle platesandare respectively placed outside of both transverse edges of the steel strip, and a height B of a lower end of each of the pair of baffle platesandwith respect to a bath surface of the molten metal bath is set to +50 mm or less, where an upper side in a vertical direction is positive.
