ANTI TERRORISM FORCE PROTECTION (ATFP)

The United States Marines defines Antiterrorism/Force Protection as a “security program designed to protect military personnel, civilian employees, family members, facilities, and equipment in all locations and situations from the calculated use of violence or threat of violence to inculcate fear, intended to coerce or to intimidate governments or societies in the pursuit of goals that are generally political, religious or ideological.”

AT/FP perimeter security systems are generally used when the highest level of protection is needed. They are used around government buildings like the Pentagon, prisons, jails, nuclear power plants, Federal Reserve banks and other high-security buildings.  ATFP systems are designed to reduce the vulnerability of and to protect lives, facilities, equipment and information. In fencing, Anti-Terrorism & Force Protection refers to how much force a structure can withstand before becoming compromised by an attacker.

The following ratings have been used to issue contracts for Crash Rated Fences since 2000:

  • K4 rating is for a vehicle traveling 30 mph

  • K8 rating is for a vehicle traveling 40 mph

  • K12 rating is for a vehicle traveling 50 mph

K-Ratings are levels of barrier protection as determined by the Department of State (DoS). A 'K' Rating is also known as a Crash Test Certification. K Ratings are given to a fence, bollard, gate, or other barrier to indicate how effective that barrier is at protecting what it is guarding by measuring the barrier's stopping power in relation to the speed and weight to an incoming vehicle. The standard unit of measurement is based on a 15,000 lb. (6810 kg.) gross weight vehicle impacting a barrier perpendicularly.

In order to be DOS certified, the barrier must not bend beyond 39 inches past the preventative impact boundary of the barrier when penetrated by a vehicle.

 

What kind of wrought-iron, steel, or aluminum ornamental type of Fence is ATFP Compliant? Steel fences are the Anti-Terrorism/Force Protection standard for high-security government buildings; but basically any commercial or residential fence can be made ATFP compliant by installing cable or beam reinforcements.

Steel cables are cemented into the ground and wrung along the accompanying fence or gate. Bollards are short and thick (iron or steel) metal posts set at even intervals. They are often times used to control traffic, but bollards can also be used to make certain fencing ATFP compliant.Reinforcement measures and ornamental fences can make AT/FP fence or gate requirements very expensive.

Part of the United States Policy on Terrorism dictates that all lawful measures to prevent [terrorism] acts and bring to justice those who commit them will be taken. Therefore, while Anti-Terrorism Force Protection fencing systems may be costly, they are often necessary.

Barbed Wire & Barbed Tape: A Cutting Edge Partnership in Security Fencing

Without a doubt, the primary use for barbed wire and barbed tape ib the US is for perimeter security. This brief will give you a better understanding of the uses and benefits of this highly effective security fence application. Both barb wire and barb tape are almost always used in precarious commercial environments. Properties where large outdoor machinery automobiles, and large property areas that are out of direct eyesight will ensure that these areas are accounted for. The aggressive appearance of the wire is sometimes thought to detract from the visual appeal and diminish a commercial property's value. In actuality, an area secured with the addition of these tried and true fence materials provide a utilitarian security that affords immeasuable fence cost benefits both short and long term use.

Barb Basics

Barbed wire is a type of fencing wire that has sharp or pointed edges typically around 5 or so inches. It is used as an inexpensive yet effective added security measure for small and large, rural and urban properties alike. Originally for farm fence, it gained urban acclaim in the early 20th Century and expanded to a means of to keep people as well as city critters out of private and restricted areas. 

Barbed wire and barb tape were brought into the mainstream farming community by this guy. Glidden refined Henry Rose's original single-stranded barbed wire design and significantly improved upon it by using two strands of wire twisted together to hold the barbed spur wires firmly in place. Glidden’s wire also soon proved to be well suited to mass production techniques, and by 1880 more than 80 million pounds of inexpensive Glidden-style barbed wire was sold, making it the most popular wire in the nation.

A person or animal trying to pass through or over a fence will surely have discomfort and obtain possible serious injury from sharp barbs. A qualified and highly skilled fence company can construct or add these commercial fence features quickly and easily. Don't be mislead by the quick turnaround of this sort of fence installation. 

Fence pros have taken the required OSHA safety courses to know how this precarious security fence application should be handled and installed.Some projects may require, five, six and even seven strands of wire may be used to maximize fence height and minimize spacing between wood farm fence installations. The wire is aligned under tension between braced heavy fence posts. The addition of barb wire is widely used in the military security, state and federal prisons, detention houses, data centers, government buildings and other national security facilities. 

One of the biggest commercial uses for fence particularly barbed wire in Virginia is for enclosed farm fencing where animals are often transported, bought or sold.Ask a fence contractor and they'll concur that more often than not, a well-built yet minimally maintained 3 of 4 wirewire fence will suffice in most instances. 

Applications

12 ½ gauge is an industrial gauge that meets military specifications. 15 ½ gauge barb wire is typically used for light commercial grade and temporary fencing. One of the benefits to 15 ½ gauge is that the barbs are sharper. Barb wire comes in galvanized and vinyl coated steel. Vinyl coated  barb can come in green or black and the actual barbs are not coated. Barbwire is made of low carbon steel wire or galvanized wire with the twisting processing by the barbed wire machines.Materials: low carbon steel wire, PVC coated wire, zinc coated wire, iron wire.

Barb Wire Uses

-Land fencing and protection
-Animal cage
-Neighborhood and Business security fencing aid.

          -fencing with chain link fence or welded wire mesh fence.

  • Features:  No stretching required when installing
  • Barbs fixed between wires
  • Adaptable for all fencing needs.  
  • Uniformly zinc coated

Typically, a new roll of barbed wire is 80 rods [1,320 feet (ft.)] in length and consists of double strand galvanized wire with barbs attached  at intervals of about 4 inches.

A lower grade barb wire can be used to prevent animals on farms and refuges, but chain link with 3 to 6 strands on top is used for commercial or military grade fence.Barbwire fencing, hurricane fence, richmond barb wire fence, rva fence, barb wire fencing richmond

Here is a handy chart to help you start the conversation with your pro fence contractor what works for your property.
Generally accepted razor lengths:
  • short razor wire has barbs from 10 mm to 15 mm long
  • medium razor wire has barbs 20 mm to 25 mm long
  • long razor wire has barbs from 60 to 66 mm long.
  • Razor wire is much sharper than the barbs of barbed wire. The sharp edges of the wire can seriously
    injure any person attempting to pass through.

A Good Starting "Point".

Always contact a local AFA, Blue Ribbon or Osha Certifed Fence Contractor.

Depending on the nature of the fence you hope to install, you should always hire a professional to make sure the job is done correctly in a timely fashion. If your fence project requires design build, an experienced security contractor or commercial fence builder is definitely the way to go. Both professionals have the knowledge and expertise to get your new fence installed safely, and as quickly as possible.

Options for Commercial Access Gates and Fence Solutions

Posted by Michelle Goodwin on Thu, Jul 03, 2014

A Professional Fence Company should have a variety options for Commercial Gate applications. The gate systems are designed to restrict unwanted entry and ensure the protection of assets and employees. Gate systems are designed to work efficiently with repeated mechanical use in any setting. Hurricane Fence Company offers the latest in Commercial Gate System trends and technology in a plethora of scales and styles. These maneuverable fence barriers can be engineered to meet the needs of everything from small Residential Secured Access to the most complex structural demands.

The following are a few examples of routinely offered Commercial Gate Systems.  

Swing Arm Gates

Swing Arms are motorized barriers that raise a steel or aluminum arm from a horizontal position to a vertical position. They give you the ability to control pedestrian and/or vehicle traffic on roadways up to 38'. These gates can have an assortment of automatic controls, such as card readers, vehicle detectors/counters, reversing logic, which causes the arm to re-open should it strike an object, and anti tailgating devices, which keep multiple vehicles from pulling through on a single cycle. A switch in a security office can also be set up to control these gates.

Many Fence Contractors also offer High Speed Swing Arm Gates that will open in less than two seconds, using either 8 or 12' arms. Heavy duty gates, with arms up to 24', are also available if gate specifications require them.

Slide Gates

Sliding Gates are often the best solution for commercial premises with busy access points. You must have room set aside for the gate in the open position. Installers can customize slide gates to accommodate a wide range of commercial applications. Many different styles of slide gates are available of which the most common is a two-rail slide gate.

There are three rail slide gates that will allow the use of almost any material you wish to face the gate. For this the commonly used materials are plastic, wood, or metal. A well set up fence supplier can also custom fabricate a slide gate to match a wide range of already existing gate styles. 

Cantilever Gates

cantaliever gate cantaliever gate

Automation of a cantilever slide gate involves the addition of a slide gate operator that can be pad or post mounted. This provides a means to open or close the gate and the addition of safety devices such as safety loops, gate edges or photo eyes. Gate operators can be added to existing gates as well as new ones and integrated into any existing access control system.

The gate itself does not touch the ground and is supported by rollers, which are attached to two large side posts.

The gate will have a tail that is used to support itself when it is in the open position. One thing to keep in mind when considering the installation of a cantilever gate is that you must have adequate overhead clearance to ensure that the gate can open fully.

Cantilever Gate Systems can be constructed with nearly any fencing material, but the distance of the opening will play an important role in determining which type of materials you can use when constructing your Commercial Gate. Lighter fabrication materials should be considered when spanning wide opening, which will make the overall weight of the gate lighter.

How Can I Make My Gate Areas ATFP Compliant?

Posted by Kristen Fugere on Wed, Sep 26, 2012

Anti-Terrorism/Force Protection (AT-FP) is generally defined as a federal security program formed to protect personnel, information, and critical resources from outside attacks. These attacks could be attempted by the use of Rocket Propelled Grenades (RPG), truck bombs, or any means of weighted attack force. Areas of planned security could include law enforcement buildings, intelligence and training facilities.

Data Center ATFP GateAT/FP Entry Systems or Gate Systems are created by using passive and/or non-passive barriers.  These gate access systems are specifically designed to reach a level of protection that the facility mandates. These mandates are found in the projects specification section and are designed by highly qualified engineers.

Passive Barriers allow the passage of entering vehicles at all times. This can be achieved by placing jersey wall barriers in away that creates a maze for the vehicle to maneuver.  This effectively forces the vehicle to slow down while permitting access.  This is only one example of this type of passive barrier.

Non-Passive Barriers are actually permanent entry obstacles. These are things like bollards, wedge barricades, drop arms, slide gates and newly designed net systems. These barricades can be used in conjunction with fences and gates or can actually be mounted to fences and gates. They are used more often than passive barriers because they can be moved in and out of their location with ease. This allows instant entry and immediately re-barricaded areas. Pop up bollards and wedge barriers are a favorite among these non-passive barriers for their reliability and relative indestructibility.

To understand the AT/FP entry systems and their requirements, one must also understand the overall perimeter requirements of the system. ATFP passive perimeter security can be accomplished with the use of steel cables or steel guardrails. This can also be setup by any combination of natural and manmade features when natural barriers are not sufficient or present. This can be achieved with ditches and berms, or large bolder (3ft. x 5ft.) placement and forestation. Distance can also be a great ATFP device when used in combination with an uneven or bumpy surface. This will slow down any moving vehicle or a truck bomb that is attempting to implode a building surface. Remember that AT/FP perimeters are specifically intended to stop only vehicle traffic. This perimeter prevents a bomb threat, not theft.  

ATFP Compliant GateIt is easier to implement the AT/FP standards when working on new construction rather than attempting to retrofit the system into an existing environment.  When retrofitting, much of the plan design work will be required to be done onsite and in an emergent way. This can lead to design difficulties and can turn out to be very costly. Conceiving a building or site around AT/FP barrier implements is much easier than situating the AT/FP elements around already existing structures. Imagine attempting to widen the distance between a building and the adjacent road line. It would be simpler to initially plan this rather than propose it at a later point in time.

Another method of obtaining this level of protection is to utilize Engineered K4|K8|K12 Ratings.  These engineered barriers have not undergone the Department of State authorized test, but does meet engineering criteria for equivalent levels of protection. Most Non-DOS Certified systems (other than U.S. Army Corp of Engineers USACE or Military Handbook MIL-HDBK specified) will require an engineer stamp indicating compliance assuring the expected level of protection.

What Type Of Fence Styles Can Be ATFP Compliant?

Posted by Kristen Fugere on Wed, Sep 05, 2012

Essentially, any type of fence can be modified to meet AT/FP requirements.

Data Center Security FenceATFP stands for Anti-Terrorism/Force Protection, as defined by the US Army and other federal entities. This term refers to the amount of force a structure can withstand without being compromised by an incoming attack.

The AT-FP ratings are achieved by reinforcing a fence structure with steel cables that run along the fence, into the ground, terminating in concrete footers. These ratings are typically referred to as crash ratings, or “K” ratings. There are three K ratings that are achievable; K4, K8, and K12. The different ratings refer to the amount of weight the structure can resist and remain intact. 

Typically, if business or government institution is going to spend this amount of money on a high tech fence, they may also want a good-looking fence. The most aesthetically pleasing type of fence that can be modified to achieve ATFP ratings is ornamental fence. Ornamental fence is often referred to as “wrought iron”, but are in fact made of aluminum or steel. Iron is an outdated material. These contemporary fence alternatives are more economical, as well as outlasting their dated counterparts. These style fences are often found around the perimeter of military institutions, data centers, federal buildings or even schools.

Alternatively, jails and other institutions that must remain secure without the superficial attributes can also apply K rated cables to chain link fences, achieving the same degree of security. These ATFP compliant chainlink fences are usually constructed of 6 gauge wire as opposed to the more commercially applied 9 gauge wire. This thicker wire, coupled with cable reinforcement and either SS 40 or SCH 40 pipe, can achieve AT/FP federal security standards.

Data Center FenceWhile ornamental styles are the most common installations of crash rated fences, even a wooden fence could be modified to reach the same standard. One way to achieve AT/FP compliance in this type of fence installation is to install a line of bollards, again reinforced with steel cables, in front of a wood fence. This would allow it to attain a K-rated fence standard. Bollards are short, vertical posts used to protect potentially vulnerable structures or objects from damage by moving vehicles. Designed for versatility, these posts range in size from 24” to 42” in height, and come in variable diameters to meet a location’s specific security requirements. Bollards can be used to maintain a more natural look, while providing crash-rated security.

As you can see, Anti-terrorism Force Protection (ATFP) standards can be met in any number of ways in the fence industry. A knowledgeable fence contractor has the capability to help customers design and build crash-rated fences out any material the customer desires. As our society continues to evolve, so do potential acts of terror, and Top Notch Fence Company’s will stay on the cutting edge of technology to continue to provide our customers with ATFP compliant crash rated fences.
