Profiled element and method for producing a profiled element

Abstract

The invention relates to a profiled element, in particular a profiled construction element, for example a profiled dry construction, façade, or plaster element, comprising an in particular metal elongated main body, in which at least one opening is formed. The opening has at least one edge formed transversely to the longitudinal extension of the main body, which edge is formed at least partially by a bent-over section of the main body. The bent-over section, together with an adjacent section of the main body, forms an at least double-layer area of the main body. In order to increase the stiffness of the profiled element transversely to the longitudinal extension thereof, the bent-over section is connected to the adjacent section within the at least double-layer area. The invention further relates to a method for producing such a profiled element.
