32、o entry: The panels can be made out of: a) zinc or zinc alloy coated wires (coated before welding); b) wires that are subsequently coated after fabrication, either with zinc or zinc alloy. In either a) or b) the panels may be subsequently organically coated. 3.2 mesh size distance measured between t
33、he centres of two neighbouring wires Note 1 to entry: Depending on the application, the mesh size can be uniform throughout the panel or varying. A uniform panel is shown in Figure 1. DIN EN 10223-7:2013-02 EN 10223-7:2012 (E) 6 Dimensions in millimetres Figure 1 Uniform panel 3.3 stiffness stiffnes
