The pattern of recesses (22) is present in an electroplated layer (21) on the external surface of the roller body; the metal layer (21) is of a hardness which is greater than the hardness of the metal of the roller body (20). The hardness of the metal of the roller body (20) is expediently up to 200 HV, and the hardness of the metal of the outside metal layer (21) at least 250 HV. The metal of the metal layer is advantageously selected from nickel, alloyed nickel and doped nickel. A roller body for use in a screen roller according to the invention is also described.
