Duo-8 A1 rated fencing system (SR1 rated under issue 7) is a double wire welded mesh fencing system, ideal for applications where Secured By Design accreditation may be required.

The SR rated fencing system offers the same product benefits as the standard Duo-8 but with added security and tamper-resistant clamp bars and fixings.

The Duo-8 SR1 rated fencing system has been Secured By Design approved by 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 SR1 (under issue 7) and A1 under issue 8.

The Duo-8 SR1 is manufactured with dual 8mm horizontal wires sandwiching single 6mm vertical wires. This produces a 50mm x 200mm mesh pattern that is strong but vandal-resistant. Duo-8 SR1 is also available in our Dualguard option with 25mm x 200mm mesh apertures, please specify Duo-8 SR1 (Dualguard) when ordering.

The Duo-8 SR1 Rated Fencing system panels are available in 2m, 2.4m or 3m in height and 2520mm wide.

Coupled with Zaun’s tamper-resistant stainless steel fasteners, the result is a rigid perimeter fence that offers a high degree of vandal resistance. In addition, with an extremely high level of visibility, this SR1 rated fencing system is ideal for additional CCTV cameras.

The posts may be supplied using either 60mm x 40mm or 80mm x 40mm Rectangular Hollow Section (RHS). Lengths of 2750mm or 3100mm may be supplied for fixing in the ground (bolt down posts are also available).  Each post has spacing at a maximum of 2525mm centres.

Installers may fix the panels to the posts with full-height 40mm x 5mm clamp bars and stainless steel fixings. The full height clamp bars create a flush safe finish with the mesh ends behind the clamp bar. In addition, an enhanced over clip is applied on the uppermost and lowermost fixings.

Suitable security toppings are also available to enhance your site’s perimeter security further.

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 and paint layers. 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 maintaining 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.
