Abstract

A hollow profile that has improved handling ability and a good ability to be attached to other components and a method for producing the hollow profile. In the method for producing a hollow profile having at least two half shell sheets, a first half shell sheet is applied to a first side of web plate along two axially running joint edges of the first half shell sheet, a second half shell sheet is applied to a second side of the web plate along two axially running joint edges of the second half shell sheet, and then the joint edges of the half shell sheets are subsequently joined to the web plate. An edge section of the web plate projects beyond the contact area of at least one joint edge so that at least one flange is formed for attaching other components. The hollow profile formed has two half shell sheets and a web plate disposed between the half shell sheets, which can form part of a vehicle body.
