A cart, hamper track, with removable liner includes a base assembly comprising a metal tubular continuous bottom frame formed of box girder construction and a top continuous metal tubular frame formed of sections certain ends of which are swaged to mate with other section ends. After mating assembly, these parts are welded together to form a non-detachable, unitary structure. Metal rods are welded to and depend from the top frame and have L-shaped bottom ends that cooperate and are supported by the bottom frame. The top and inner sidewall surfaces of the bottom box frame define openings that receive and support the horizontal end of the upstanding rods. The bottom frame also comprises two U-shaped butt welded sections. Openings are also defined in the frame member parts to enable excess paint to exit these parts during manufacture.
