Anti Climb Fencing HiSec Plus | High Security Fences | Zaun

10. HiSec Plus

Zaun’s HiSec Plus is an anti-climb fencing system for security applications. Using the popular ‘358’ welded mesh configuration on the attack face of the mesh, this unique panel also features additional wires to the rear to add additional strength and security to repel thieves, trespassers and intruders.

The HiSec Plus attributes make this system an excellent solution for security applications as the combination of increased vertical wire diameters of 6mm (compared to 4mm on standard 358) and double horizontal wires on the rear every 254mm provide a rigid and visually appealing option to the standard HiSec range. In addition, the close-mesh configuration of 76.2mm x 12.7mm ensures that it would be challenging to get a finger or foothold on the mesh fabric to scale and climb with additional climbing aids.

Using full-length clamp bars and fixings every 400mm (maximum), making it very difficult to lever and prize away from the post. The panel is flat against the post, and the panel ends are held against the post by a front plate which makes levering the panels off very difficult. The HiSec Plus system is available in single panels of up to 5.2 metres in height and 2515mm in width.

To ensure we can supply a complete, single solution, pedestrian and vehicle access solutions have also been carefully designed to address both aesthetic requirements and maintain the same security level of the mesh. Also ideal for integrating with CCTV, PIDs and security topping enhancements such as barb and razor coils, all supplied as part of a complete turnkey solution.


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.

Sloping Ground
