CPNI Rated Fencing | ArmaWeave Plus | High Security | Zaun Ltd

11. ArmaWeave® Plus CPNI Approved Fencing

ArmaWeave® Plus CPNI Rated Fencing system has been designed for installation on sites of critical national importance (CNI). Developed specifically for sites that need the highest possible level of perimeter protection.

The CPNI approved enhanced fencing system offers a more substantial delay from attack from hand and power tools than other traditional welded mesh fencing systems. Thanks to its tighter mesh pattern and use of high tensile steel wires.

The mesh properties are maintained because of the careful design to eradicate risk from attack. ArmaWeave® Plus CPNI rated fencing system is our highest rated high-security fencing system, giving a maximum delay from forcible attack.

ArmaWeave® Plus high-security fencing also offers seamless integration with detection systems, including PIDs, CCTV and topping enhancements.

Tested and approved for UK government use by CPNI (contact CPNI for details) and various government departments. ArmaWeave® Plus meets the current criteria for a forcible attack. Also tested and approved by the MoD to use with most of the markets leading PID Systems.

The tight woven mesh pattern offers no climbing aids and provides little room for blades and cutting tools to attack the fabric.

The unique properties of the ArmaWeave® Plus CPNI rated fencing system has the ability to be raked. Thus, limiting the need for stepping panels on slopes and reducing installation costs significantly compared with standard welded mesh systems while still conforming to the highest-rated standards for fencing products defending against forcible attacks.
