Abstract: A support and a process for preparing the support are disclosed. The support includes a metal pipe having two ends, a pair of plugs and a covering tube. The plugs are positioned in each end of the metal pipe and are formed from a thermoplastic resin. The plugs each include an outer portion having an outside diameter that is equal to the outside diameter of the metal pipe. The covering tube is formed from a thermoplastic resin that is compatible with the thermoplastic resin forming the plugs. The covering tube covers and closely contacts the entire outer surface of both the metal pipe and the outer portions of the plugs.
