摘要：
A method of manufacturing a beam comprises rolling, in a longitudinally profiled rolling process, two flange pieces (6,7), such that one surface (8) of each rolled flange piece is profiled according to a predetermined thickness profile; and joining (12,13) the rolled flange pieces together via a web of the beam or by profiled surfaces of the flanges.
