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.

Abstract: A wall assembly suitable for use on ships and offshore drilling platforms and in similar applications requiring fire resistance, low weight, and strength. The wall assembly includes a light weight principal panel having first and second fiber reinforced polymer skin layers joined to a core, and a metal frame adhered to the skin layers without any through fasteners. The frame preferably includes a first metal plate adhered to the first skin layer and a second metal plate adhered to the second skin layer and welded to the first metal plate. The frame is preferably welded to a metal support structure. The wall assembly may be used as a deck, floor, roof, vertical wall, gate or door.
