Abstract
A rolled product of metal with at least one structured surface with light spreading structure. The structured surface exhibits a groove-type pattern in the form of a series of circular arc lengths that runs in the roiling direction and is wave-like in cross-section. The maximum angle of inclination of a tangent to the circular arc lengths with respect to a plane defined by the surface is 1 to 15°, and the radius of the arc lengths is between 0.1 and 20 mm.
