摘要： A planishing roll has a surface structure, in particular for producing flat products from a metallic material, in particular from a steel material. The surface structure has a material ratio of 2% at a depth of 0.2 μm to 9 μm, preferably at a depth of 0.8 μm to 5.5 μm. The depth is measured, starting from a zero line, in the direction of an axis of rotation of the planishing roll, with the zero line running parallel to the axis of rotation of the planishing roll and. Starting from the surface of the planishing roll, the zero line is displaced in the direction of the axis of rotation of the planishing roll until the material ratio of the planishing roll is 0.1%.
