Abstract

The invention proposes a steel section and a method for hot-rolling a steel section with recesses to be rolled in periodically at the flange ends, which emanate from a flange joint. For deep and long recesses (6, 8), the invention specifies certain material flow conditions and flow cross-sections and design guidelines for the grooved roll producing the recess. Rolled steel sections of this kind are used to form components made up of individual sections (1, 2, 3) and for connecting them together positively. <IMAGE>
