STEEL PROFILE, SUPPORTING PROFILE AND METHOD FOR PRODUCING A STEEL PROFILE
The invention relates to a method for producing a steel profile comprising the steps of providing (A) a metal workpiece (2; 406), in particular a strip steel workpiece, having a thickness of at least 5 mm, forming (C) a weakened point in the region of an intended bend (13) in the metal workpiece (2), and bending (D) the metal workpiece (2) to produce a bend (13) on the metal workpiece (2). The method is distinguished by the fact that the machining (b) of the metal workpiece (2) is carried out before the bending (D). The invention also relates to a steel profile and to a supporting profile.
