A waste container has an axle assembly comprising an axle with opposing axle end caps adapted to mount the wheels of the waste container. The axle comprises a metal rod encapsulated in plastic. An annular axle groove is formed near the ends of the axle in the encapsulating plastic. The metal rod provides the necessary strength for the axle and the encapsulating plastic protects the rod from corrosion while permitting the formation of the annular axle grooves used for mounting the axle to the wheel. The axle can easily be injection molded, reducing the cost and manufacturing time of prior axles while still providing corrosion protection.

[ What is claimed is:] [16.]16. In a wheel assembly comprising an axle with a groove at an end portion thereof, a wheel with a central hub having an opening passing therethrough for receiving the axle, a wheel retainer to retain the wheel on the axle and having a lug extending radially inwardly into the groove in the axle to secure the retainer to the axle, the improvement comprising:the axle comprises an elongated body formed of a molded synthetic resin and with the groove integrally formed in the elongated body at an end portion thereof; and a reinforcing rod encapsulated within the elongated body to form an internal support therefor and to strengthen the elongated body sufficiently to avoid undesirable deformation or failure of the axle during loading of the axle.
