Abstract
A structural member comprises an elongated hollow thin metal shell and a concrete filler moulded into the hollow thin metal shell. A pair of reinforcing end pieces is engaged in both ends of the shell and is embedded in the concrete filler in order to prevent both ends of the shell from deforming in the process of injecting concrete mortar into the shell and to prevent both end portions of the structural member from rupturing or breaking during transportation or construction thereof.
