Abstract
A roll for a hot-dip metal coating bath has a substantially cylindrical shape. At least an outer peripheral surface of the roll is formed of a ceramic material. A relatively coarse groove is formed on the outer peripheral surface of the roll in a direction crossing the rotation axis. A plurality of relatively fine grooves is formed in the bottom surface of the coarse groove along the longitudinal direction of the coarse groove. In place of the fine grooves extending in the longitudinal direction of the coarse groove, a plurality of rows of fine grooves may be formed along the crosswise direction of the coarse groove.
