22、ements for steel wire welded mesh panels for fencing. The panels are used for fencing parks, schools, sport stadia, public buildings, factories, airports, military sites, etc. This International Standard specifies the general characteristics of welded mesh supplied as panels and recommended coatings
23、, properties and tolerances. This International Standard is applicable to panels made from round or shaped wires not thicker than 10 mm. The panels have round, rectangular or triangular wires and double horizontal wires. The use of V-shaped vertical wires is optional. 2 Normative references This Eur

31、llowing terms and definitions apply. 3.1 welded panels panels of various shape and design, made by electrically resistant welding at each wire intersection NOTEThe panels can be made out of: a) zinc or zinc alloy coated wires (coated before welding); b) wires that are subsequently coated after fabri
32、cation, either with zinc or zinc alloy. In either a) or b) the panels can be subsequently organically coated. 3.2 mesh size distance measured between the centres of two neighbouring wires NOTEDepending on the application, the mesh size can be uniform throughout the panel or varying.
