<p>#CMT# #/CMT# The flat metal element has a center area (28) comprising at least two sections (29,30) each consisting of two outer lying sub-sections (31,33,34,36) with a center sub-section (32,35) in between. The outer sub-sections are folded over in relation to the center sub-section to create an opening (22,23). The two sections of the center area form a part of the edge of the opening. The center area, inclusive of the two sections, is formed in one piece with edge areas (26,27) of the metal element. #CMT# : #/CMT# An independent claim is included for a use for the metal element which, among other things, may be for a profiled element, especially as a corner or support section, protective screen, fence section, filter mat or noise protection element. #CMT#USE : #/CMT# The metal element, among other things, may be for a profiled element, especially as a corner or support section, protective screen, fence section, filter mat or noise protection element. #CMT#ADVANTAGE : #/CMT# The openings in the metal element can be formed with no material loss, and at the same time no stresses are present inside the material. Furthermore, the metal element has high rigidity and in relation to the original material makes possible a large material expansion. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows two stages of manufacture of the flat metal element. 22,23 : opening 26,27 : edge areas of metal element 28 : center area 29,30 : sections of center area 31,33,34,36 : outer sub-sections of center area sections 32,35 : center sub-sections of center area section.</p> |
