A high-security fence that resists for more than 10 minutes sustained attack with specialist power tools has been developed by steel mesh fencing manufacturer Zaun.

Zaun has received a revised Certificate of Product Approval from the Loss Prevention Certification Board (LPCB) to include its brand new CorruSec SR4 approved to Security Rating 4.

The fencing system incorporates corrugated HiSec fencing sandwiched between panels of Super10.  CorruSec SR4 has been subjected to sustained attack by testers from the Buildings Research Establishment (BRE) wielding category D tools, including 12V jigsaws and disk grinders, axes including an 850mm felling axe, a hooligan bar, 1.5kg lump hammer and 500mm long bolt cutters.

The fencing system is approved at heights from 2.8 to 6m above the ground, while options for 300mm of buried fencing, toppings and stepping up gradients of up to 19.5º are included in the design.

Further Zaun security systems have achieved Security Ratings including their HiSec Super10, Duo8 and HiSec 358 systems (certificate number 1164a/05) and are entered into the Red Book for LPS 1175: Issue 7.

To maintain accreditation and a listing in the LPCB Red Book, manufacturers must regularly demonstrate to independent auditors that they are producing products consistent with those tested.
