We would look primarily at the mesh aperture, wire diameter, steel grade/coating, and posts, rather than simply the brand name. There are several companies in South Africa selling products under the Clearview/ClearVu/clear-view description, and the quality of the actual fencing system can differ substantially. For example, manufacturers advertise locally manufactured high-security mesh, while other suppliers offer different mesh, coatings and post systems and furthermore, not all Clearview systems are suitable to coastal applications. Matrix Fencing can give you a proper South African market comparison of the major Clearview brands (e.g. Betafence Betaview, Guardiar, WireView, Cochrane and other locally available systems) and tell you which one I would position as the premium product for Matrix Fencing, including the best specification for coastal properties. Our recommendation For maximum residential security: - 76 × 12.7 mm (High-Density) is a high security choice. For a good balance of security and price: - 76 × 25 mm (Medium-Density) is an excellent choice. - 76 × 50 mm is more economical and provides good perimeter security, but it is less resistant to intrusion than the smaller apertures. The general principle is straightforward: the smaller the aperture, the harder the fence is to climb and penetrate. Clearview systems are specifically marketed around anti-climb, anti-cut characteristics and maintaining visibility for CCTV and surveillance.
