Zaun’s 358 mesh, HiSec, uses the popular ‘358’ welded mesh configuration to repel potential intruders.

The 358 mesh security fencing attributes make it an excellent solution for high security applications. This fact is reflected by its use by the Home Office for prison facilities in the UK.

The close mesh formation therefore ensures that it is almost impossible to climb, and difficult to cut without power tools. Zaun has developed three fixing methods, ensuring the most appropriate and flexible solutions are available to meet specific installation specifications.

Whether you are using our ‘spider’ clip system for low risk sites, or our dual fix or single fix clamp bar system, HiSec 358 mesh system can work to mitigate the risk of potential attack.

For high security sites, the panel ends are held against the post by a single fix clamp bar which as a result makes levering the panels off very difficult.

The 358 security mesh system is available up to 5.2 metres in height in a single panel due to our leading system technologies and in-house manufacturing

To ensure we are able to supply a complete, single solution, pedestrian and vehicle access solutions have been carefully designed to address both aesthetic requirements along with ensuring the same security level of the mesh is maintained.

The 358 mesh system is also ideal for integrating with CCTV, PIDs and security topping enhancements such as barb and razor coils, all of which can be supplied as part of a complete turnkey solution.

Each system may also be galvanised only or galvanised and polyester powder coated in your choice of RAL colours. For a full list of colours Click Here.
