The invention relates to a device for coating metal bars ( 1 ), particularly steel strips, by hot dipping. At least some sections of the metal bar ( 1 ) are vertically guided through a container receiving the molten coating metal ( 2 ), said metal bar ( 1 ) being guided by at least one roller ( 4 ) which runs on bearings. In order to increase the service life of the roller bearings, the roller, or at least the axis ( 5 ) thereof, penetrates the side walls ( 6 ) of the container ( 3 ) and is mounted outside the container ( 3 ).
