Wire Rope Perimeter Security

The renowned Bristorm Anti-Vehicle Fence consists of an arrangement of high tensile steel ropes supported on steel line posts and secured by anchors posts. All steel components are galvanised for protection from the environment and the high modulus of elasticity of the steel ropes means that re-tensioning is not required. This combination results in minimal maintenance costs thus ensuring a cost effective, high security fencing solution is implemented to protect your perimeter from vehicle borne attacks. All Bristorm Hostile Vehicle Mitigation (HVM) Perimeter Fences are tested to PAS 68 and will mitigate 7500Kg vehicles travelling at speeds of 30, 40 and 50 mph.
