The CorruSec C5 (SR3) Fencing System represents the next generation in high-security perimeter protection, designed and manufactured by Zaun to meet the most demanding physical security standards.

Using a corrugated steel mesh core sandwiched between HiSec front and rear mesh panels, the system achieves LPS 1175 C5 (SR3) certification, providing a minimum delay of five minutes against toolset C. This construction offers exceptional rigidity and resistance to cutting and prying, making it ideal for protecting utilities, defence assets and critical national infrastructure.

Panels are 2.5 metres wide with 2540 mm post centres, a maximum 2.4-metre corrugated infill, and a minimum overall height of 2.4 metres. Both in-ground and base-plated options are available, using double rows of security fixings to maintain structural integrity under sustained attack.

Each component benefits from a zinc protective layer and polyester powder coating to BS 1722-16, ensuring a life expectancy of 15–20 years in standard environments, with enhanced marine coatings available for harsher C2–C5M conditions. Panels can be stepped or adapted to sloping ground, maintaining consistent security performance across varied terrain.

Built and tested in the UK, CorruSec C5 (SR3) embodies Zaun’s philosophy of Protection Through Innovation, offering a proven and trusted fencing solution for high-risk applications around the world.
