Abstract
A method for making a beam from a metal sheet ( ), includes the steps of providing a metal sheet having opposite first and second side edges ( ) extending longitudinally along opposing sides of the metal sheet, and a first and a second generally parallel opposing face surfaces ( ) provided between the first and second edges. The first and second generally parallel opposing faces define a thickness of the metal sheet therebetween. The thickness of the metal sheet is split at one of the first and second side edges to form first and second integral flanges ( ) from a portion of the metal sheet such that inner ends of the first and second flanges remain integrally connected with an unsplit portion ( ) of the metal sheet. The first and second flanges are then bent so as to provide the metal sheet with a tubular portion extending along one side of and integrally formed with the unsplit portion. The first and second flanges are then fixed against movement relative to one another.
