METHOD FOR PRODUCING METAL FENCINGS (VERSIONS) AND FENCING OBTAINED WHILE IMPLEMENTING METHOD Russian patent published in 2018 - IPC E04H17/00 

FIELD: construction.

SUBSTANCE: method for producing metal fencings, which is characterized by manufacturing a decorative element of a fence span by cutting it by a CNC plasma cutter from a metal sheet, fixing the decorative fence element to a support, characterized in that the fence framework is made of a single metal profile or two metal profiles of the round, or U-shaped, or rectangular cross-section, the ends of which are pre-bent, and then the two framework parts are welded together by their ends; each decorative element of the fence span being formed from two identical parallel curves, which form the edges of the detail edge of the decorative element; the ends of each decorative element are then welded to the top part and the bottom part of the frame, forming the required pattern of the decorative elements inside the span. When cutting with a CNC plasma cutter from the metal sheet, the edges of one decorative element part form the front edge of the next part. Preferably, the welding process of all the elements of the fence span is carried out at the installation site.

EFFECT: simplifiying the technological operations with the possibility of creating a variety of forms of decorative elements, simplifying the transportation of the fencing elements and the fencing compactness, saving the metal consumption while manufacturing a fencing section.
