- Utility and energy infrastructure
- Prisons and custodial environments
- Sensitive data and communications facilities
- Commercial and industrial premises
- Critical infrastructure and restricted compounds
- High value storage and operational sites
Key Benefits of SR3 (C5) High Security Fencing
The complete system complies with LPS 1175 SR3 (C5) Issue 8, providing a recognised classification for demanding perimeter-security specifications.
The system uses multiple 50mm x 50mm x 5mm RSA rails plus two 100mm x 50mm x 6mm RSA rails per standard bay. IPE or universal-beam posts are selected according to the fence height.
The mesh uses 4mm horizontal and 10mm vertical wires at 76.2mm x 12.7mm spacing. This narrow format restricts grip and access while retaining visibility through the perimeter.
High-grade T-head bolts, cup-square bolts and security nuts connect the pales, rails, cleats and stabilising components, helping protect critical system connections.
CombiGuard is available from 2400mm to 5200mm high. On systems above 3000mm, the mesh continues above the palisade section to achieve the required overall height.
Steel components are hot-dip galvanised or pre-galvanised as specified and polyester powder coated to a minimum thickness of 100 microns. Moss Green and Black are the standard colours.
