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.

Bristorm LP (and IVP)


  • Tested to BSI PAS 68
  • Effective protection from 4×4 vehicles crossing rough ground approaches
  • Captures vehicle within the fence after impact
  • Visually unobtrusive with clear line of site
  • Minimal maintenance
  • Standard ground anchors reduce cost, and installation time
  • Can be close coupled with Anti-Personnel fence products (IVP)
  • Fast and easy installation


Bristorm LP and IVP has been developed to protect long perimeter sites from 4×4 vehicle attacks travelling at speeds up to 40 mph. Extremely economical, Bristorm LP is a visually unobtrusive and cost effective measure ideal for securing a perimeter from vehicle borne attack.

Bristorm LP, tested to BSI PAS 68, is an extremely effective Hostile Vehicle Mitigation (HVM) solution where long exposed perimeters are surrounded by uneven ground, such as airports, military installation and power stations etc.

IVP adds to the LP system with the ability to incorporate an anti-personnel fence in close proximity. The system allows close installation and shared foundations and therefore reduces installation costs. Impact from a vehicle only damages the anti-personnel fence at point of impact, leaving the rest of the perimeter intact and functioning.
