Perimeter & Hostile Vehicle Protection, Vehicle Security Bollards & Barriers, Entrance Protection

Bristorm Perimeter Fences

The Bristorm fence is a wire rope vehicle security barrier designed to meet the specific threat of penetrative / ram attack by Vehicle Borne Improvised Explosive Devices (VBIED).

Bristorm 30, 40, 50 and LP fences consist of substantial main anchors, galvanized steel wire ropes and lightweight line posts, the Bristorm fence can withstand vehicle ramming attacks at 90 degrees to the fence line, absorbing the energy of the impact before repelling the vehicle and maintaining the vital stand-off distance.

The Bristorm Integrated Vehicle Personnel ( IVP) fence employs a dual post system that connects a standard anti-personnel fence to any of the standard Bristorm fences, allowing vehicular impact protection up to 7500kg at 50mph (80km/h). Combining the benefits of Bristorm fence with standard anti-personnel fence types allows massive flexibility at minimal cost. The Bristorm IVP brings Hostile Vehicle Mitigation (HVM) and anti-personnel protection into a single foundation without altering the performance of either system. This allows the IVP to sit significantly closer to that which it protects, meaning that it can be utilised across a vast number of sites and situations where distance between perimeter and asset is limited.

Bristorm Beam Perimeter Fence

Bristorm Beam is a new and innovative perimeter security barrier comprising a specially developed double height beam used in combination with tensioned wire ropes. It is a robust, shallow depth barrier that can withstand an impact from a 7500kg truck travelling at 30mph. Although superficially resembling a corrugated highway barrier, Bristorm Beam shares no major components with the lower rated highway safety systems.

Developed to meet the needs of sites where underground services limit the depth of excavation, the Bristorm Beam is an economical and steadfast alternative to bollards and fences. End anchors have a foundation depth of only 500mm and in many cases line posts are secured to an existing surface by chemical anchors. If a suitable surface is not present then a simple shallow beam foundation is all that is required.

The minimum installed length is 24m. There is no theoretical limit on the distance between anchor points however Bristorm recommends a maximum spacing of 200m to allow the easy tensioning of the ropes.

Bristorm Bollards

The Bristorm Bollard has been developed to complement the Bristorm anti-vehicle fence and is ideal for protecting small areas of a perimeter from vehicle ramming attack. Manufactured from steel tube and cast into a reinforced concrete foundation the Bristorm Bollard can be installed individually, in small groups, or as a complete perimeter line. The bollards are positioned so that the gap between neighbouring bollards is no more than 1200 mm. The flexibility of the Bristorm Bollard allows complex areas to be protected economically, and provides an easy way of increasing the security of small awkward areas. Bollards have the useful feature of being able to allow pedestrians to pass through the perimeter with the minimum of obstruction, but yet provide an effective countermeasure to unauthorised vehicle access. Bristorm Bollards can stop a 7500kg truck at 50mph.

Designed to withstand direct impact energies in excess of 1,800kJ, the bollard provides protection from extreme Vehicle Borne Improvised Explosive Device (VBIED) attack to sites where aesthetics and public perception are a consideration.

The Bristorm bollard can be installed with an optional electro-hydraulically raising / lowering unit to allow for vehicle access within the protected perimeter.

The new Bristorm Shallow Bollard has been developed for installation above services providing discrete protection against hostile vehicles. It has a foundation depth of just 400mm and can stop a 7500kg truck travelling at 30mph. Ideal for areas where services prevent deeper foundation products from being used.

Bristorm Roadblockers

Bristorm Roadblockers provide a high level of security against unauthorised vehicle access. Designed to withstand direct impact energies in excess of 1,852kJ, the blocker provides protection to sites from extreme Vehicle Borne Improvised Explosive Device (VBIED) attack.

The RB 780 CR is an electro-hydraulically operated blocking system with segment widths from 2m to 6m (in 500mm increments) and a height of 800mm when fully raised. The hydraulic power pack is controlled by a Programmable Logic Controller (PLC) enabling connection of virtually any access control to the blocker. The PLC can be configured to enable the Roadblocker to be raised in under one second in an emergency by using an optional hydraulic accumulator.

The Low Foundation Roadblocker RB 880 CR, has foundation depths of only 300mm and is ideal for use where the installation of a conventional roadblocker would interfere with existing underground services.

Available in 2m widths, the blocking segment has a raise height of 1,000mm to ensure that vehicle penetration during attack is kept well within the DoS / British minimum standard requirement for both US and European manufactured vehicles.
