CPNI Enhanced Fencing ArmaWeave® Woven Mesh | Zaun

01. ArmaWeave® CPNI Approved Fencing

Zaun’s ArmaWeave® woven mesh high-security fencing has been designed specifically to be installed on sites of critical national importance (CNI).

The CPNI approved 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 of 17mm x 17mm and use of high tensile steel wires.

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

The unique properties of the ArmaWeave® CPNI approved fencing system means that this fencing system has the ability to rake. Thus, limiting the need for stepping panels on slopes and reducing installation costs significantly compared with standard welded mesh systems. Yet, still conforming to the highest-rated standards for fencing products defending against forcible attack.

Tested and approved for UK government use by CPNI (contact CPNI for details) and various government departments. ArmaWeave® meets the current criteria for a forcible attack. ArmaWeave has also been tested and approved by the MoD to use most of the market-leading PID Systems.

ArmaWeave® CPNI approved fencing also offers seamless integration with detection systems, including PIDs, CCTV and topping enhancements.

Unique Raking Abilities

ArmaWeave® CPNI approved fencing system, designed with specific tolerances enabling the system to rake and follow the site’s topography without compromising security or system rigidity. This makes ArmaWeave® the world’s only raking mesh system.

These unique raking abilities makes the system much easier to install on-site. Reducing civil work and additional civils for additional posts for stepping. Raking the panels on-site reduces the need for specially fabricated panels and pre-measuring of angles on site. Reducing cost for installation and material.

Posts & Fixings

The ArmaWeave® perimeter security fencing system features a post and clamp bar configuration, providing a simple and easy installation method. Supplied with bolts, nuts and washers and installed using either power or hand tools.

Note: For CPNI, the maximum change of direction is 45°. A flange is welded at the post at 45°, or a post with two welded flanges at 22.5°.


Posts are available in different lengths to accommodate panel heights and ground conditions. Additional variations are also available:
