A doctor beam for use in a printing unit, e.g. a flexographic printing unit, wherein the doctor beam has a front side with a U-shaped channel, wherein the doctor beam is made of metal and includes a surface coating produced by Plasma Electrolytic Oxidation (PEO), the surface coating at least covering the U-shaped channel, and wherein the doctor beam further includes a non-stick ceramic coating, whereby is achieved the possibility of using metal for making doctor beams without risking their degrading, neither due to chemical impact of the applied inks/lacquers/primers nor due to the destruction of the surface coating by cleaning liquids. The invention also concerns a method for treating the surface of a doctor beam and use of a doctor beam.
