Who Requires Cable Reinforcement On Security Fences And Gates?

Posted by Dawn Lowndes on Thu, Feb 03, 2011
Cable fence reinforcement consists of 2 cables stretching laterally at heights of both 30 and 35 inches. The specific heights are set at 30” to address cars and 35” for trucks. These cables can be installed to meet the Anti-Terrorism Force Protection (ATFP) standards as detailed below. They are typically placed in conjunction with chainlink fence as an additional measure to stop a vehicle from penetrating any perimeter.

Cable reinforcement is commonly used by military bases, military and civilian airports and at nuclear power and industrial plants.  In addition to these federal institutions utilize this product for reserve banks, the Federal Bureau of Investigations and many other government offices.

Higher levels of protection are essential in the previously mentioned target areas for the protection of products, personnel and the general public.

Some specific examples of areas protected by cable reinforced fences or gates are:

Military – housing, equipment facilities and personnel offices.

        Airports - foot traffic, planes, fuel trucks and access roads.

        Industrial plants - toxic and explosive materials as well as vital power grids.

        Financial businesses with large structures and mass amounts of employees.

Over the last two decades, the Department of State established an Anti-Terrorism Force Protection (ATFP) rating system to help prevent vehicles from entering a facility’s perimeter and creating a bomb threat.  When deciding on an Anti-Terrorism Force Protection (ATFP) cable system one needs to review the following criteria for need:

Is this facility a potential target for terrorist to attack?

Where would this potential assault originate? 

Are there roads leading into the property in question?

Are there parking lots in which a car could achieve a speed with which perimeter penetration could occur?

When deciding what your threat area may be, you will need to determine the level of protection desired by determining what level of security is required at the facility.  For example a nuclear power plant would more than likely require a K-12 higher rated security fence.

There are K ratings for cable reinforcements that assist in determining impact and speed volumes. They are as follows:

  • A K-4 system, which is two 3/4" cabling with concrete anchoring deadman will stop a 15,000 pound vehicle traveling at 30 miles per hour.
  • A K-8 system with two 3/4" cabling and 1" cable with concrete deadman will halt a 15,000 pound vehicle at a maximum speed of 40 miles per hour.
  • A K-12 systemwith three 1" cables will prevent penetration of a 15,000 pound vehicle with a maximum acceleration 50 miles per hour.

When determining your needs and selecting a system make certain to knowledgeably assess your desired level of protection. The rate specificity can affect installation costs. When choosing your fence company it’s always a good idea to get at least three references on similar type projects.  If you no clarity on what to look at to determine your need a qualified fence professional will be able to help you in this process.
