PROBLEM TO BE SOLVED: To provide a process for continuous galvanizing of a metal strip capable of attaining an extremely low defect density for satisfying the request of a customer demanding a surface free from visual defects, and to provide an apparatus therefor. SOLUTION: In the process and the apparatus for the continuous dip-coating a metal strip 1 in a tank 11 containing a liquid metal bath 12, the metal strip 1 is made to run continuously through a duct 13, the lower part 13a of which is immersed in the liquid metal bath 12 to form a liquid seal 14 on the surface of the liquid metal, and a natural flow of the liquid metal from the surface of the liquid seal 14 is set up in two overflow compartments 25, 29 made in the duct 13 and each having an internal wall which extends the duct 13 in its lower part, and the level of liquid metal in the compartments is maintained at a level below the surface of the liquid seal 14.
