It is important to recognize that Security Fences alone will not stop a determined intruder. To be effective, security fences need to be augmented with personnel and other means of support. Security Fences are used to accomplish the following:
a) Define the perimeter of a restricted area
b) Provide a physical and psychological deterrent to entry
c) Prevent accidental entry
d) Optimize security force operations
e) Enhance detection and apprehension of intruders
f) Channel and control the flow of personnel and vehicles through
Additionally, the amount spent on security protection should be based on the cost of the item protected, “possible damage that the loss of the item could inflict upon the civilian population, and the importance of the item to the overall security and readiness posture of the command.”
Chain-Link Fence is the most common way to enclose restricted areas at military installations. Federal Specification RR-F-191 is the primary document for security fence requirements. While Chain Link Fencing is expensive (though much less so than Ornamental), it is relatively easy to maintain and provides intruders with little ability to conceal themselves.
Recent terrorist events involving suicide –type crash vehicles has led to the reinforcement of security fence using cables when trying to protect certain restricted areas. Tests have shown that adding a cabling system to existing chain link fence greatly restricts the potential penetration of vehicles. K4 barriers will stop a 15,000 pound vehicle traveling 30 mph, K8 will stop a 15,000 pound vehicle traveling at 40 mph and K12 will stop a 15,000 pound truck traveling at 50 mph. Hurricane Fence has the experience and expertise to furnish and install all levels of security fence currently available in the market.
Some examples of additional barriers are:
1. Active (pop-up) vehicle barriers
2. Active and passive bollards
3. Across the road bar-type barriers
4. Dragnet systems
5. Concrete planter boxes and jersey bounces
6. Buried heavy equipment tires
7. Concrete and concrete block walls
8. Highway type guard rails and cable systems.
