An installation includes a first fixed return roller, positioned above the melted zinc bath level and along which passes the band to be galvanized, when exiting from a galvanization tromp. A second return roller is mounted on a mobile arm and guides the band, after galvanization to an excess metal removing device. A coating roller, mounted on a mobile arm is adapted to be brought to two positions, a first position where it dips into the zinc bath for coating a determined face of the band, and a second position where it is moved clear of the path followed by the band. A bottom roller is supported by a mobile arm so as to be movable to two positions, a working position at the bottom of the tank, so as to provide for the immersion of the band in contact with such roller for carrying out galvanization of both faces, and a rest position clear from the path followed by the band.
