To provide a hot dip metal coating apparatus realizing more speeding up.
A blade type wiping apparatus 20 is arranged on the part at which a steel strip 1 comes out from the upper face of molten zinc 2 in a plating tank 10. The blade type wiping apparatus includes a pair of blades 22 supported by a blade support apparatus 21. In each blade 22, the downstream side is formed from a thin, almost wedge-shaped sheet, in the edge parts on the upstream and downstream sides, each cross-section is rounded so as to be a circular-arc shape, and it is tilted so that the edge part on the downstream side is made close to the steel strip 1 than the edge part on the upstream side. The molten zinc flows along the inside of each blade, and the lift of a large quantity of molten zinc by the steel strip is prevented, so that a load on a gas type wiping apparatus 30 arranged in the upper direction of the blade type wiping apparatus is reduced, splashes are less prone to occur, and speeding-up is made possible.
