摘要
Disclosed is a process for manufacturing an elongate steel beam such as an I-beam. Such beams have at least one flange portion and a web portion extending from the flange portion in a depth direction of the web portion. An initial elongate workpiece is provided, the cross sectional shape of the initial elongate workpiece varying with position along the workpiece. The initial elongate workpiece is then rolled so that the variation in cross sectional shape of the initial elongate workpiece is transformed into a corresponding variation in cross sectional shape of the web portion and/or of the flange portion with position along the beam.
