ABSTRACT OF THE DISCLOSURE The present invention provides a lintel for supporting arches over doors, windows and like openings in a wall. The lintel is made of relatively thin sheet metal and has at least one load-carrying shank so that the lintel in spite of its thin construction can carry great loads during the walling of the arch. Each shank is provided with a longitudinally extending material weakening e.g. a series of slots, perforations, or at least one groove. The material weakening forms a fracture indication along which the shank can be folded or broken off, when the mortar has set and the brickwork has become self-supporting.
