03. HiSec A1 (SR1) Rated Fencing

HiSec SR1 fence from Zaun uses the popular 358 welded mesh configuration. Ideal for use in applications where Secured by Design accreditation is required. The HiSec SR1 fence system attributes therefore make it an excellent solution for high security applications including schools, prisons, utility suppliers or anywhere that a physical security protection is required.

The HiSec SR1 fences use the prison mesh configuration therefore making the fence system almost impossible to climb and very difficult to cut without power tools.

HiSec SR1 fence panels are available in 2.0, 2.4 and 3.0 metre in height. Coupled with Zaun’s tamper resistant fasteners, the result is a rigid perimeter fence that offers a high degree of vandal resistance and an extremely high level of through visibility.

The HiSec SR1 fence system offers the same product benefits as the standard HiSec, but with added security. Manufacturing is subject to stringent quality control, means all fences are of a uniformly high quality.

This system conforms to BS 1722: Part 14: Category 4 and carries certification to LPS 1175 SR1. This is required for Secured by Design and featured in the BRE Red Book.

To ensure we are able to supply a complete, single solution. Pedestrian and vehicle access solutions, carefully designed to address both aesthetic requirements. In addition to ensuring the same security level of the mesh maintained.

This SR1 fence is also ideal for integrating with CCTV, PIDs and security toppings, supplied as 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 layer and the paint. 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 maintenance of 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.
