The invention relates to a wall element of sheet metal, comprising a general wave shape consisting of a succession of waves, each comprising substantially rectangular plate parts mutually connecting at chosen angles, wherein all connecting lines between adjacent parts are mutually parallel, wherein a first part is followed by a second part connecting thereto at an angle, the second part is followed by a third part connecting thereto at an angle, such that the first and the third part are mutually parallel, the third part is followed by a fourth part connecting thereto at an angle, the fourth part is followed by the first part of a subsequent wave, and so on, characterized in that at least a number of the first and/or third parts are strengthened by a plate adhered thereto at least in each associated middle zone. |
