Zusammenfassung:	FIELD: technological processes, metal processing. ^ SUBSTANCE: invention concerns rolling-mill production, particularly cold-formed section bars. Roll-formed section bar is shaped as channel or angle of two cold-formed stripe bars and features shelves and bent areas. Shelf edges carry "locks" formed by outer stripe edges bent inwards by 180°. ^ EFFECT: extended usability of roll-formed sections at lower cost. ^ 4 cl, 1 dwg, 2 ex
