A roll for use in a galvanizing pot comprises a hollow body 10 to be brought into contact with a steel strip, and shaft portions 20 connected to the body. The inner surface of the body 10 comprises large-diameter regions 10a on both sides and a small-diameter region 10b in the center. Each shaft portion 20 has a small-diameter portion 20a, a flange 20b and a large-diameter portion 20c, the large-diameter region 10a of the body 10 being connected to the large-diameter portion 20a of the shaft portion 20. Each shaft portion 20 is provided with pluralities of longitudinal grooves 25 extending through the large-diameter portion 20a and the flange 20b, the grooves 25 forming apertures 25a communicating with the inside of the roll when the shaft portions 20 are connected to both end portions of the body 10.
