Abstract

The present disclosure relates to a method for producing rectangular or square wall elements from flat sheet metal, including determining a length and width of a wall element, providing a flat sheet metal piece incising two longitudinal edge portions to form two incisions to form two tabs for each longitudinal edge portion separated by a respective incision from the remaining longitudinal edge portion, right-angled folding of a respective strip, formed by the incisions, right-angled folding of the tabs parallel to the longitudinal edge at the level of the base of the associated incision, right-angled folding of the longitudinal edge portions along the longitudinal edge, right-angled folding of the transverse edge portions parallel to the transverse edge to form a strip having a width corresponding to the transverse dimension of the tabs, and right-angled folding of the transverse edge portions along the transverse edge.
