Surface treated, corrosion protected, metal object, the metal surface (2) of which presents a chosen surface structure and is coated with at least one coating layer (7) having a very even surface structure. The surface structure of the metal surface is profiled with a topography which presents uneven recesses (3) and protrusions (4) and which has also been provided with a surface having an area which is enlarged at least 4 times in relation to the very even surface (9) of the coating layer (7), by means of which a reduced velocity for the spreading of corrosion is obtained, as regarded in relation to the surface of the surface layer. |
