Body for a machine comprising a body cavity for receiving material

A machine comprising a body mounted to a chassis, the body comprising:

• a front wall at a front end of the body;
• first and second side walls extending from the front wall to a rear end of the dump body, the first and second side walls each comprising a top side rail;
• and
• a base extending from the front wall to the rear end and between the first and second side walls such that the front wall, first and second side walls and base at least partially form a body cavity for receiving material, wherein:
• each top side rail comprises an upper side surface and a flange extending upwardly from the upper side surface adjacent to the body cavity, the upper side surface extending downwardly and outwardly away from the flange for directing material from the top side rail and away from the body cavity, wherein the flange is harder than the upper side surface.
