Our Approach

Trust Your Security Needs to the Company That's Been Doing it Since 1977

A total systems approach to access control and physical security requires integrating all security components including fences, gates, lights, alarms, etc. Because of terrorist tactics, vehicle bollards become essential elements in an effective physical security program. When integrated properly into a total system, vehicle bollards can satisfactorily meet this threat to sensitive resources.

Threats to Installations & Facilities 

Threats to installations and facilities can be from individuals with authorized access or from those with little or no affiliation with the installation. Levels of force, number of personnel involved, tools, and methods used vary and are determined by the perpetrator. The bollards manufactured, distributed, and installed by Superior Bollards are designed primarily to protect the assets within the installation.

Threat Assessments

When evaluating vehicle bollards, particular attention must be focused on the weights and velocities of vehicles that could be used to breach perimeter security. Failing to use the proper equipment to counter the threat may lead to a false sense of security.

Barrier Capability

Vehicle crash resistant bollards should be used at vehicle access points to sensitive areas. Supplemental gate and fencing reinforcements may also be needed to optimize vehicle bollard effectiveness.

Barrier Selection

The bollard system can be passive or active. Normally, an active system with the bollard in the active position, which must be deactivated to permit access, is preferable to one that must be activated to prevent access. The bollard must be capable of safe operation and activation from a remote location and must have high reliability.

The Problem

A vehicle moving towards a bollard has kinetic energy which is one measure of how much "hitting power" it possesses. Kinetic energy is derived from the vehicle velocity and its weight (mass). The amount of kinetic energy posed by a vehicle changes by the square of its velocity. For example, a vehicle moving at 90 KPH has 25 times as much kinetic energy as it would have moving at 16 KPH.  An armored car weighing 30 times as much as a compact car and moving at 10 MPH would have LESS HITTING POWER than the compact moving at 100 KPH !

Minimizing Impact

Because velocity is so crucial to total kinetic energy in the moving vehicle, every effort should be made by the security engineer to force the vehicle to slow down before it reaches the barricade. The most frequently used technique is to require a sharp turn immediately in front of the bollard. If the car speed can be reduced by 2/3, then the force of impact will be reduced by 9 times. Wherever possible, avoid a long straight shot at a control point.
