CorruSec SR4 Fencing | LPS1175 SR Rated Fencing | Zaun

06. CorruSec D10 (SR4) Rated Fencing

CorruSec D10 (SR4) fencing is a patent-pending innovative high-security fencing system designed and developed by Zaun. Independently tested by BRE and entered into the RED BOOK, CorruSec D10 SR4 Fencing successfully passed and achieved the security rating LPS1175 SR4 under issue 7 and D10 under issue 8.

A unique construction specifically designed to provide a minimum delay time of at least 10 minutes when independently tested following the BRE SR4 testing protocol. The specially configured mesh system has been independently tested to defeat various attack methods, including hand and power tools. Ideal for protecting assets, including water utility sites, oil and gas compounds, data centres, and other critical, national importance (CNI). The robust fencing solution also provides good visibility for use with CCTV camera systems.

CorruSec D10 (SR4) is configured using HiSec Super 10 to the front and rear panels and a corrugated HiSec 3/5/10 mesh panel in the centre. Each flat panel features a 76.2mm x 12.7mm mesh configuration with 4mm horizontal and 10mm vertical wires. In addition, a buried version of CorruSec D10 (SR4) is available, where the rear HiSec Super 10 panel is replaced with standard HiSec 358.  Whichever configuration is used, care must be taken with weed suppression to ensure weeds cannot grow inside the fence.  This would apply to ANY multi-layer fence from any supplier.  The corrugated section was pressed to approximately 80mm in depth. All three layers are bolted together using bolts fixed into a grid pattern throughout the combined fence panel.

At a minimum height of 2.8 metres high, CorruSec D10 (SR4) features a maximum corrugated infill of 2.4 metres high. Supplied with widths of 2.5 metres with 2540mm post centres with a double row of fixings. Posts designed using 80x80mm SHS and available in either bolt down or in-ground post options. Full panel assembly fixed to the posts using 80mm full height clamp bars with fixing centres of 9 inches (228.6mm).


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 CorruSec perimeter security fencing system features a post and clamp bar configuration, providing a simple and easy installation method. Supplied with 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.


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

Note: If CorruSec is buried, careful consideration must be given to weed control to ensure vegetation does not grow between the panels when installed.

What is LPS 1175 for SR4 Fencing?

LPS 1175 is the requirements and testing procedures for the LPCB approval. A listing of intruder resistant building components, strong points, security enclosures, and 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 LPCB, the UK Government, Insurers, and the Police. It has rapidly become a core element of physical security specification across many sectors.

The standard comprises several security ratings with test requirements of ascending intensity. Measured in terms of attack tools and also time available to the attacker. This enables specifiers to select products according to the risks that they and their property face. LPS 1175 is used in a range of applications, from residential rights to critical infrastructure projects. (more…)
