Abstract
An elongated metal frame structure for connecting a large elongated container to a vehicle employed in transporting the container. The frame comprises a plurality of aluminum alloy tubes connected together at certain corners of the frame by corner assemblies. The assemblies comprise a 'standard' cast iron or steel fitting and at least one steel member connected to one face of the fitting. The exterior surfaces of each steel member are coated with materials that are effective in electrically separating the steel member from an aluminum tube of the frame when the corner assemblies and aluminum tubes are assembled together. The size of the steel members in cross section with the materials applied to the surfaces of the steel member is such that the steel member can slip into the end of the aluminum tube located at a corner of the frame.
