SR2 Rated Fencing System | B3 Rated Fencing | Security | Zaun Ltd

04. HiSec SR2 (B3) Rated Fencing

HiSec SR2 Rated Fencing (B3 Rated Fencing under Issue 8) has been developed by Zaun in consultation with the Home Office as our premier high-security system. Aimed at high profile and sensitive sites requiring the greatest perimeter protection.

The HiSec SR2 Rated Fencing solution is based on the original 358 HiSec system but is even stronger. HiSec SR2 is manufactured with 4mm horizontal wires and 10mm diameter vertical wires with 76.2mm spacings, providing a strong barrier to anyone trying to gain unauthorised access to a site.

The SR2 rated fencing system has also achieved Secured by Design accreditation from the Association of Chief Police Officers and Security Rating certification to LPS1175 and entry into the Red Book from the Buildings Research Establishment (BRE), achieving the security rating B3 under issue 8 (SR2 under issue 7).

HiSec SR2 uses the RHS post configuration with a full-length clamp bar and stainless steel through bolts, washers and nuts to leave no weakness in the fence line. Slotted fixing holes ensure the installation is easy and leaves a neat, flush fitting.

Despite all this, HiSec SR2 presents a value solution that negates the need for a double skin 358 system or any additional clamp bars or fixings that you wouldn’t expect in a standard mesh fencing system. This keeps installation costs down to a minimum.

HiSec SR2 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.


Finish

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 the 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.

Posts & Fixings

The HiSec Super SR2 perimeter security fencing system features a post and clamp bar configuration, providing a simple and easy installation method. Supplied with stainless steel through bolts, washers and nuts and installed using either power or hand tools.


Sloping Ground

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


Variations

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


Matching SR2 / B3 Rated Security Gates

Pedestrian gates are single leaf 1.2m wide (or width to suit), framed in a 50mm x 50mm RHS with Zaun HiSec mesh clad to the front face of the gate frame, with slide latch. Gate supplied with 2 x suitable gate posts.

Vehicle access gates are double leaf (single leaf vehicle gates available) 3.0m wide (or width to suit), framed in 50mm x 50mm RHS, with Zaun HiSec mesh clad to the front face of the gate frame, with drop bolts and slide latch. Gate supplied with 2 x suitable gate posts.

What is LPS1175?

SR Ratings and LPS 1175 is the requirements and testing procedures for the LPCB approval. A listing of intruder-resistant building components, strong points, security enclosures, free-standing barriers, fencing, and gates.

LPS 1175 covers the broadest scope of physical security products and services of any publicly available standard globally. LPS 1175 results from many years of work by LPCB, the UK Government, Insurers, and the Police. It has rapidly become a core element of physical security specification across many sectors. More…
