It is a system created by mounting a PVC-coated wire mesh on a metal frame that determines the field boundaries around sports fields and prevents the balls used in sports competitions from coming out. Pipe material, in the dimensions specified in the project, in the desired pipe and wall thickness, is mounted on previously installed flanges with the help of welding, usually every three meters around the site. In accordance with the field size or project, vertical pipes are assembled together with horizontal pipes at desired points and in desired sizes by welding. All additional points in the system are assembled perfectly with the help of welding. The joints will be opened in the shape of a wolf’s mouth and welded in this way. Steel tension rope or tension wire is mounted on the created metal frame. Then, 50x50x3.50 mm or 40x40x3.50 mm PVC coated wire mesh is assembled and attached to the metal frame with the help of tie wires. Pedestrian gates are installed in the desired area of the field. All metal parts will be electrostatic oven painted.
