Super 6 358 HiSec | Perimeter Security Fencing | Zaun Ltd

02. HiSec Super 6 CPNI Approved Fencing

HiSec Super 6 358 mesh was developed in consultation with the Home Office. Aimed at high profile and sensitive sites that require greater perimeter protection. HiSec Super 6 358 is based on the standard HiSec 358 mesh system. Still, it is even stronger, presenting a stronger barrier to anyone trying to gain unauthorised access to key assets and sites than standard 358.

The 4mm horizontal wires remain the same as the standard HiSec 358 mesh; however, the vertical wires are at 6mm diameter rather than the standard 4mm. The mesh pattern remains 76.2mm x 12.7mm, providing excellent visibility for use with CCTV cameras and other detection technology.

Supplied with tamper-proof fixings and full-length clamp bars to provide additional security for any intruders trying to break into the fence line. Typically supplied with panels overlapping at the post, but also available in a double-slotted clamp bar version if required.

HiSec Super 6 358 can also be used with a range of fence toppings and integrated solutions to provide a full turnkey high-security solution. Pedestrian and vehicle gates are also available to match the fence line.


All Zaun posts/panels/gates and painted auxiliary components (for example, clamp-bars, slide bolts etc.) benefit from a protective zinc layer and electrostatically applied polyester powder coating to BS1722 p16. Care is taken with pre-treatment to ensure sound adhesion between the zinc and paint layers. In a UK C1 environment, as defined in ISO 12944 p2, this should ensure a useful life expectancy of the fence of at least 15-20 years. Life expectancy in all environments can be extended by maintaining the fencing with regular washing. Useful life will be reduced if the fencing is damaged. Any coating damage should be repaired to reduce the effect on useful life.

Enhanced painting systems such as marine coatings are also available for improved life expectancy in C2-C5M environments.

Posts & Fixings

The HiSec Super 6 perimeter security fencing system features a post and clamp bar configuration, providing a simple and easy installation method. Supplied through 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°.

Sloping Ground

Panels can be stepped as required on the post. However, it is recommended that taller panels are either part-buried or additional posts are used on steeper gradients. Panels can also be sloped to follow lesser gradients.


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

Who is CPNI?

CPNI (Centre for Protection of National Infrastructure) is the government authority for protective security advice to the UK national infrastructure. Their role is to protect national security by helping to reduce the vulnerability of the national infrastructure to terrorism and other threats.

CPNI heavily promote the theory of deterring and detect so that protective security is put in place or built into the design, security measures or protocols to reduce the consequences of an attack.

CPNI advice on physical security, personnel security and cybersecurity/information assurance also explain how these components combine and reinforce each other to protect assets. More…
