Abstract: Provided is a metal strip for a pipe with which the weight of a pipe can be reduced while maintaining the strength of a joint portion that tends to be structurally the weakest. A metal strip L is formed by rolling. The thickness of each of a head end portion 1a and a tail end portion 1b, which are longitudinal end portions 1, is greater than the thickness of an intermediate portion excluding the longitudinal end portions 1. The metal strips are connected to each other in series by welding, and a pipe is made by performing a pipe-forming operation.

Abstract: A method of manufacturing a furcated composite post (1) comprising at least two strips (7, 8) that are joined together along their length in a furcated manner. The method comprises the steps of feeding one or more of the strips (7, 8) at a set rate to working rolls of a roll mill for profile rolling to a desired cross section/profile, feeding the strips (7, 8) at the same set rate to positioning rolls for holding the strips (7, 8) in a correct orientation for joining, and joining the strips together, preferably by welding the strips (7, 8) along their length.
