PURPOSE:To improve and control optionally the hot dipped thickness and the surface state of deposited metal by passing a long material through a molten hot dipping bath which is pressurized in the pressure higher than the atmosphere. CONSTITUTION:The following melting vessel 4 for hot dipping metal is used which is provided with an introduction hole 1 of a material to be hot dipped, a die 2 and a pressurizing device 3. The molten hot dipping metal 5 is pressurized in about 3kg/cm<2> pressure higher than the atmosphere with the pressurizing device 3. A metallic material 6 to be hot dipped is run into the molten metal 5 through the introduction hole 1 and drawn out through the die 2. By this method, the amount of the molten hot dipping metal adhered on the metallic material 6 such as a streak is increased and it is hot dipped in uniform thickness.
