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 m to 9 m, preferably at a depth of 0.8 m to 5.5 m. 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%.

This invention relates to thermal spray coatings and processes onto non-smooth surfaces. The coating and processes can coat non-smooth surfaces without substantial degradation of the underlying surface texture or profile of the non-smooth surfaces so as to sufficiently preserve the underlying surface texture or profile. The ability for coating fractional coverage to maintain the surface profile while maintaining wear resistance is unprecedented by conventional thermal spray processes.

Provided is a hot-dip galvanized steel sheet used for an automobile outer panel and so forth and, more specifically, to a method for producing a hot-dip galvanized steel sheet having excellent press formability and clarity after painting, and to a hot-dip galvanized steel sheet produced by the method.

An apparatus and method for rolling aluminum sheet uses a texture roll to roll the sheet while is it hot and has reduced yield strength. The texture rolling may be used to remediate defects in the sheet at a variety of stages in rolling, and may facilitate subsequent rolling stages.

A method for manufacturing parts is provided. The method includes cold rolling a substrate with work cylinders whose work surface has a roughness Ra.sub.2.5 of less than or equal to 3.6 m, depositing the metal coating on at least one face of the annealed substrate by electrodeposition to form the metal sheet and deforming the cut metal sheet to form the parts. The outer surface of the metal coating has a waviness Wa.sub.0.8 of less than or equal to 0.5 m after the deformation step. A part and vehicle are also provided.
