    In practice both the roll and the strip surfaces are rough. In many rolling processes, the roll grinding process leads to a roll roughness with a pronounced lay, with asperities running along the rolling direction. This longitudinal roughness is in turn transferred to the strip. Isotropic roughness is also common, for example where the
