Anti-Ram Vehicle Barrier Fences

\r\n

What is an anti-ram vehicle barrier fence?

\r\n

An anti-ram vehicle barrier fence, also known as an anti-ram fence, is commonly installed on sites requiring more protection than a typical chain link barrier can provide. These high-security fences are specifically designed and tested to prevent Hostile Vehicle Attacks (HVA) and Vehicle Borne Improvised Explosive Device (VBIED).

\r\n

Anti-ram fencing can provide perimeter security against vehicle-borne assaults around an entire building, commercial facility, airport, correctional facility or military base. These anti-ram fence barrier systems provide a high level of protection for personnel, buildings, equipment, and hazardous materials that could be vulnerable to high-speed collisions, whether deliberate or accidental.

\r\n

How Does a Vehicle Barrier Fence Work?

\r\n

Many commercial sites, industrial and chemical plants, oil refineries and government locations are surrounded by high-security road barrier fences. Chain link fencing using standard 2 3/8ths inch diameter posts is simply not strong enough to stop penetration from a 50 mph truck loaded with explosives. Much stronger construction materials, utilizing high-level engineering, are required for anti-ram vehicle barrier fence border protection. Once designed and manufactured, expensive, live crash tests at certified testing labs must be conducted.

\r\n

What is a vehicle barrier anti-ram K-rating?

\r\n

There are several ratings test standards which can sometimes be confusing. In 1985, the Department of State (DOS) created K-ratings. They were later revised in 2003. A K-rating measures how far the front bumper of a standard 15,000-pound truck penetrates a vehicle barrier or barrier fence. In order to receive a K-rating, this distance must be less than 50-feet.

\r\n

For instance, a K-rated fence system’s stopping power is tested by crashing a 15,000-pound vehicle into the fence at a specific speed. How fast it is traveling will designate its K rating:

\r\n

K4 - 30 miles per hour
K8 - 40 miles per hour
K12 – 50 miles per hour

\r\n

The measured penetration distance is then designated by L1, L2 or L3. Each represents a specific incursion range:

\r\n

L3 = less than 3.3 feet.
L2 = 3.3 – 20 feet.
L1 = 20 - 50 feet.

\r\n

So a “K8L3” means the truck was traveling 40mph and was stopped with less than 3 feet of penetration.

\r\n

What is an ASTM F2656 anti-ram crash rating?

\r\n

ASTM International, formerly the American Society for Testing and Materials (ASTM), developed a newer rating called ASTM F2656 that currently is more widely used than K-ratings. Like K-ratings, ASTM F2656 also incorporates size of vehicle (15,000 lb.truck) and its traveling speed. M ratings share similarity to K ratings in that each tests standardized speeds of 30, 40 or 50 mph. For example, a vehicle barrier fence could have the following designations:

\r\n

M30 classification - A vehicle barrier fence rated for a 30 mph impact.
M40 classification - A vehicle barrier fence rated for a 40 mph impact.
M50 classification - A vehicle barrier fence rated for a 50 mph impact.

\r\n

As always with ratings, penetration distance is key. Instead of an “L”, ASTM F2656 ratings use a “P” designation that indicates how far the motor vehicle penetrates the barrier. P ratings range from P1 to P4. Using the vehicle barrier fence example, these are the possible designations for penetration distance:

\r\n

P1 - The vehicle moves no more than 1 meter (3.3 feet) past the vehicle barrier fence.
P2 - The vehicle moves no more than 1.01 to 7 meters (3.31 feet to 23 feet) past the vehicle barrier fence.
P3 - The vehicle moves no more than 7.01 to 30 meters (23.1 feet to 98.4 feet) past the vehicle barrier fence.
P4 - The vehicle moves further than 30 meters (98.41 feet) past the vehicle barrier fence.

\r\n

In summary, a M50 P1 rating translates to a 15,000 lb. truck traveling 50 mph being stopped by a vehicle barrier or anti-ram fence with less than 3.3 feet of penetration. It is imporant to note that unlike K-ratings, ASTM has no penetration distance limitation. P4 means that the penetration measurement exceeded 98.41 feet. Because of P4's \"unlimited\" distance, virtually any tested product can earn a P4 rating. For this reason, DoD only accepts ratings P1-P3.

\r\n

Are ASTM F2656 ratings better than K-ratings?

\r\n

ASTM ratings are valuable because they can also test a wider range of vehicle sizes. This is vitally important as hostile vehicle attacks increase using different types of transports to deliver destruction.

\r\n

C-ratings designate a small Car (2430 lbs.)

\r\n

PU-ratings designate a Pickup truck (5070 lbs.)

\r\n

H-ratings designate a heavy vehicle (65,000 lbs.)

\r\n

What is a PAS 68 rating?

\r\n

Created by the British Standards Institution (BSI), many international organizations use PAS standards. A PAS68 rating can be intimidating due to its lengthy, Algebraic-looking formula that represents multiple factors, including weight and type of the vehicle, speed, angle of impact, penetration distance and debris dispersion. PAS68 ratings are similar to ASTM and K-ratings in that they are a measurement of protection against higher speed vehicles (30, 40 or 50 mph). A PAS68 rating looks like a math formula from high school: V/7500 [N1]/48/90:0/0 – it might look a bit daunting so let’s break it down.

\r\n

V stands for Vehicle test

\r\n

3,500(N2) = weight and vehicle type

\r\n

48 = speed (48 kph or 29.83 mph)

\r\n

90 = angle of impact in degrees

\r\n

0 = penetration distance

\r\n

0 = how far major debris traveled after impact

\r\n

Ballistic Resistant Fences

\r\n

What are ballistic resistant fences?

\r\n

Ballistic resistant fences, often mistakenly called “bulletproof fences”, are designed and manufactured to protect people and property inside the fence perimeter from gunfire outside the fence line. Like their counterparts, ballistic resistant doors and ballistic resistant windows, bullet resistant fences must be rigorously tested.

\r\n

What materials are used to make ballistic resistant fences?

\r\n

Ballistic security fences can be made of fiberglass composite panels as well as steel or aluminum. Often overlays of fiberglass/resin composite panels are attached to expanded metal fencing to achieve the desired ballistic resistant protection.

\r\n

What locations use ballistic resistant fences?

\r\n

The need for and use of a bullet resistant fence is a function of your location and its inherent threat risk. Traditionally, ballistic resistant fencing was used to protect military bases from hostile sniper fire. Embassies in volatile regions also incorporate ballistic fencing in their perimeter security plan. However, ballistic fencing is being used more and more in “civilian” and commercial settings like airports. Schools and universities have begun using this perimeter protection as active shooter incidents have increased.

\r\n

A very concerning new threat emerged in 2022, electrical substation attacks. The challenge with protecting electrical equipment from gunfire is integrating ballistic protection with non-conductive fencing. When incorporating additional security protections, it is always advisable to consult and expert and insure that you comply with the Institute of Electrical and Electronic Engineers (IEEE) grounding requirements.

\r\n

How are ballistic resistant fences rated?

\r\n

There are several rating standards to test ballistic protection. One of the most common, if not gold standard, is UL 752. Manufacturers also use the ballistic standard developed by the National Institute of Justice. Also applicable is ASTM F2781 -- Standard Practice for Testing Forced Entry, Ballistic and Low Impact Resistance of Security Fence Systems.

\r\n

Are there bulletproof fences?

\r\n

It is vitally important to remember that while the term “bulletproof” is commonly used, there is no such thing as a bulletproof door, window or fence. Every round fired into ballistic resistant material degrades the stopping power. Fire enough rounds and eventually the material will fail. Firepower is also pertinent. Composite material that can stop a 9mm bullet doesn’t necessarily protect against a round fired from an AR-15. Understanding that no fence is bulletproof is essential to designing and installing effective perimeter security.

\r\n

What is perimeter security?

\r\n

Perimeter security involves high security fencing as well as personnel, additional physical deterrents and intrusion detection technology. Intrusion detection products include:

\r\n

Infrared and thermal cameras
Security lighting
Silent alarms
Motion detectors

\r\n

Available physical deterrents can include:

\r\n

Curved anti-climb palisades
Barbed wire
Spike toppers
Concertina razor wire

\r\n

What is the best security fence?

\r\n

This depends entirely on your project and numerous factors like location, function, threat assessment and budget. There is no “one-size-fits-all” high security fence. This is why it is vitally important to determine your location’s threat risk.

\r\n

Are ballistic resistant fences expensive?

\r\n

Yes, compared to residential chain link fencing. Perimeter security applications are highly customizable depending on location, dimensions and security needs.

Anti Climb Fences

\r\n

What is an anti climb fence?

\r\n

An anti climb fence, sometimes called anti climb security fencing or anti scale fencing, is precisely what it is named – a fence you cannot climb. These security fences prevent Intruders from achieving grip and footholds by employing tightly spaced welded wire, wire mesh, expanded metal, perforated metal and/or narrowly spaced palisades as the infill material between posts and rails. This design creates an unclimbable fence or unscalable fence.

\r\n

Some anti climb fences are designed with an outward curved top section that creates an impossible angle to overcome. Several anti climb palisade fences use this outward curve atop the fence along with a pointed spear-like end to further deter intruders. Many of these fence systems also offer additional security options like Concertina razor wire and barbed wire as well as motion detectors and security lighting.

\r\n

What is the difference between welded wire and wire mesh?

\r\n

Welded wire is professionally referred to as “welded wire mesh” and this inclusion of the term “mesh” is where confusion begins. Welded wire consists of perpendicular or orthogonal steel wires that are connected at their cross sections/intersections using resistance welding (or electric resistance welding). This process uses a strong electric current to heat up the two metal components until they melt at their resistance points (where the wires intersect) whereupon pressure is applied to forge them together. This forms a very strong grid of openings, or apertures, that can be sized according to need and design. When welded wire is used for anti climb fencing, the apertures are extremely tight or small to prevent foot and hand holds as well as protect against compromise by breaching tools.

\r\n

Woven wire mesh, often shortened to “wire mesh”, adds to the aforementioned confusion since both materials can be called “mesh”. Wire mesh is made from individual steel wires literally woven like cloth into an interlocking pattern. Generally, depending on the gauge (thickness) of the wire, woven wire mesh is more flexible and less resilient than welded wire.

\r\n

What is expanded metal and perforated metal infill?

\r\n

Expanded metal is a process where small cuts are made in a sheet of metal and then the entire piece is stretched (expanded) making larger, pre-determined apertures. Like welded wire, these small apertures prevent scaling and breaching.

\r\n

Perforated metal is a similar process in that the metal sheet has shapes (holes) punched out in various patterns and sizes.

\r\n

Are palisade fences anti climb fences?

\r\n

Many palisade fences are anti climb fences depending on how close together the “pales” are spaced. Pales are similar to pickets, the vertical bars or square tubes one often sees on wrought iron fences. Pales, however, are much stronger because they are made from roll formed steel and attached directly to the strength of the horizontal fence materials.

\r\n

Originally, palisade fences were made of wood and were called stake fences because the pales were imbedded in the ground. A perfect example of this is the stockade forts of the old US West that used sharpened logs buried vertically in the ground to create a palisade fence.

\r\n

Today’s modern steel palisade fences incorporate horizontal rails to affix the pales so they are not buried in the ground as an anchor point. You can find the best palisade, anti climb fences instantly using the Protogetic Filter.

\r\n

Where are anti climb fences used most?

\r\n

While there are consumer rated anti climb fences suitable for residential properties, more typically one encounters this level of security at high value target locations such as nuclear and electrical power plants, airports, chemical and petroleum storage facilities and military installations. A no climb security fence not only keeps intruders out, but it also can keep people within their required confines like prisons and psychiatric facilities as well as bridges and overpasses at risk for accidents or suicide attempts.

\r\n

Are anti climb fences the same as anti-ram fences?

\r\n

In short, no. A security anti climb fence is not necessarily designed to prevent a Hostile Vehicle Attack (HVA). However, some manufacturers do make anti-scale fencing that is anti-ram. For an anti climb fence to qualify as an anti-ram barrier, the perimeter fencing has to be tested just like an anti-ram vehicle barriers using ASTM F2656 criteria. You can find one of these special fences instantly at Protogetic.com.

\r\n

What are the advantages of an anti climb fence?

\r\n

An anti climb security fence prevents human compromise of the protected perimeter. The very small aperture of the infill material prevents scaling by eliminating hand and foot holds. These infill materials are typically steel and include: palisades, welded wire mesh, expanded metal and perforated metal. They are extremely robust so they can further slow or even thwart attempts to cut or breach the fence itself. This also makes most anti climb fences penetration resistant, sometimes simply called an anti-cut fence.

\r\n

Are all anti climb fences penetration resistant?

\r\n

Not at all but many are because penetration resistant fencing can be achieved by creating a very small aperture in the infill material – in simple terms, this means the spacing of the mesh or welded wire is so small that it prevents tools from fitting in the openings and thus cannot exert any leverage or bite to cut the wire infill. As such, it also prevents climbing. Some of these infill systems have such small apertures that they even limit or completely screen visibility should complete privacy be required.

\r\n

What other security options are available for an anti scale fence?

\r\n

Similar to blast resistant doors, many anti scale fences are also customizable in their sizing as well as security options which include, spike toppers, Concertina razor wire, barbed wire, ballistic shield, motion detectors, infrared sensors and security lighting.

\r\n

How high is an anti-climb fence?

\r\n

Anti climb fence heights, like regular residential fencing, vary by location and security levels. Research indicates that security fencing should be no lower than 2.1 meters or 6’ 10 inches high. Quite obviously, the higher the fence – the more difficult it is to climb. Exactly how tall your fence needs to be to provide optimal security is also a function of budget as well as building and zoning codes. Many anti climb fences can be custom made or come in predetermined panel heights ranging from 8 feet to 20 feet. The Protogetic Filter helps you find the right height fence for your project instantly.

\r\n

What materials are used in anti climb fencing?

\r\n

Most commonly, an anti scaling fence is made from steel, galvanized steel or stainless steel. This includes the vertical fence posts and the horizontal rails. The infill material, whether welded wire, wire mesh, perforated metal, expanded metal or palisades, is also usually steel though they can be made of aluminum, copper, brass and titanium.

\r\n

Are all non climbable fences metal?

\r\n

There are unclimbable fence types that are non metallic and thus non conductive. These security fences are made of special fiberglass composites or fiberglass reinforced polymers. Installing a non conductive, non climbable fence is critical when securing unique locations like power generating facilities and sub stations where some metal fences could accommodate current leakage and flashover voltage (where a high voltage electric current is accidentally discharged) thereby creating a dangerous, if not deadly, result. If your needs require a metal anti climb fence to surround a sub station or power plant, you need to make sure it complies with the Institute of Electrical and Electronic Engineers (IEEE) grounding standards.

\r\n

A non-conductive fence is also best installed where radar is active, like airports. A metal, non climbable fence can reflect radar, creating more interference patterns compared to a non-conductive fence. Protogetic has non-conductive fences from leading manufacturers. Tired of searching the internet? You can instantly find an anti climb, non-conductive fence using the Protogetic Filter for free!

\r\n

Are anti climb fences expensive?

\r\n

An anti climb fence utilizes infill material that is stronger, tighter spaced and less flexible than a chain link fence. More material that is higher quality of course costs more. Some anti climb security fencing relies on engineering to curve the upper portion of the fence outward as well as make connections and hardware inaccessible to cutting or being used as a foot or hand hold. These added security designs also add to the cost, making a no climb security fence more expensive than traditional chain link or picket fencing.

Demark Boundary Fences

\r\n

What is a demark boundary fence?

\r\n

A fence is said to be a demark boundary because it legally separates two properties. For practical purposes, it defines the property lines of your home and your neighbor’s. Besides defining legal ownership, demarcation fences also provide security by creating a perimeter boundary. The Department of Defense actually requires high security demark boundary fences to be installed at military bases and government facilities both as a warning that a facility is restricted and to delay or prevent incursion.

\r\n

What is perimeter security?

\r\n

Perimeter security requires a comprehensive plan that prevents unauthorized entry into a property or facility. It not only involves protective fencing but also:

\r\n

Equipment
Security Personnel
Access control

\r\n

What are demark boundary fences made of?

\r\n

In retail/consumer terms, a demark boundary fence can be nothing more than a simple wood picket, wrought iron or chain link fence. For high security demark boundary fences, the materials are engineered to be far more robust in order to resist or prevent breaching by manned attack or vehicle ramming. Rolled steel and aluminum are the most common materials used.

\r\n

Can a demark boundary fence also be a high security fence?

\r\n

Yes. There are many demark boundary fences that are also rated for numerous threats. Protogetic highly recommends that a threat assessment be performed to identify the best type of perimeter fencing for your project, including:

\r\n

Ballistic protection
Anti-ram
Penetration resistant
Anti-climb

\r\n

What security options are available for demark boundary fences?

\r\n

Demark boundary fences can be outfitted with surveillance and intrusion detection devices as well as physical deterrents.

\r\n

Infrared & thermal cameras
Motion detectors
Security lighting
Alarm systems
Warning signs
Barbed wire
Concertina razor wire
Spike toppers

\r\n

Is infill and fence fabric the same thing?

\r\n

Yes. Fence infill, or “fence fabric as the Department of Defense calls it, refers to the protective material that prevents entry between the fence panel’s frame posts and the top/bottom rails. The most popular infill material is chain link, but this is but one of many infill options available for fencing, depending on your budget. Besides chain link, other infill options include:

\r\n

Expanded metal
Wire mesh
Palisade
Non-conductive
Metal screen
Welded wire
Tubular pickets

\r\n

What type of demark boundary or security fence is best?

\r\n

No fence is impenetrable given enough time, tools, skill and manpower. There is also no one size fits all solution to perimeter security fencing. The best fence for your project is determined by a through examination of the risks and threats that could be in play. Once again, hiring a qualified security expert or engineer to perform a threat assessment is our first recommendation.

\r\n

What if my demark boundary fence needs to be DoD-approved?

\r\n

You’re in luck. Protogetic has developed and launched an industry-first, 100% digital, DoD Anti-Ram Vehicle Barrier List. You can find exactly what you need in seconds!

\r\n

How much do demark boundary security fences cost?

\r\n

Nearly every project in the protective design industry is unique. Many manufacturers will custom make exactly what your project requires. It should be no surprise that high security demark boundary fencing, access control products and anti-ram vehicle barriers cost more than the residential products found in home improvement stores.

Non-Conductive Fences

\r\n

What is a non-conductive fence?

\r\n

Like all high security fencing, a non-conductive fence demarks a boundary that is restricted as well as prevents or delays intrusion of that perimeter. However, most importantly, non-conductive fencing serves a very specialized purpose – protecting against electrical dangers like current leakage or flashover voltage or interference patterns that can adversely affect radar function.

\r\n

What materials are used to make non-conductive fences?

\r\n

Fiberglass composites or fiberglass-reinforced polymers are typically used to manufacture non-conductive security fences.

\r\n

What locations use non-conductive fences?

\r\n

Because non-conductive fencing is excellent at protecting against current leakage and flashover voltage, it is often used to secure the perimeter around power plants and electrical substations. Flashover voltage occurs when a dangerously high electrical current is discharged, endangering or even killing personnel and damaging equipment in close proximity. Protogetic recommends consulting with experts to make sure your fencing adheres to the grounding standards of the Institute of Electrical and Electronic Engineers (IEEE).

\r\n

Why do airports use non-conductive fences?

\r\n

Metal fencing is known to interfere with and reflect active radar. Since it is non-metallic, a non-conductive fence does not create interference patterns that disrupt an airport’s or airliner’s radar and instruments.

\r\n

How are non-conductive fences rated?

\r\n

One of the most commonly used standards is Unified Facilities Criteria -- UFC 4-022-03. Non-conductive fences that also protect against forced entry or gunfire are tested and rated by ASTM F2781 -- Standard Practice for Testing Forced Entry, Ballistic and Low Impact Resistance of Security Fence Systems.

\r\n

Can non-conductive fences also protect against other security threats?

\r\n

Yes. Non-conductive fences can also be anti-climb/climb resistant as well as anti-cut/penetration resistant or ballistic resistant. Depending on the project and threat/risk level, these are important considerations, especially with data showing increased attacks on the electrical grid and vulnerable substations.

\r\n

Are there impenetrable fences?

\r\n

The short answer is No. It is vitally important to remember that given enough time, attacking personnel and breaching tools, all fences can be breached. This must be kept squarely in mind when designing and implementing a perimeter security strategy. A non-conductive fence’s primary purpose is to protect personnel and infrastructure from dangerous or possibly fatal electrical discharge or interference. Its secondary goal, common to virtually all fences, is to create an imposing barrier & psychological presence that delays or deters attacks.

\r\n

What is intrusion detection?

\r\n

Intrusion detection is equipment specifically designed to surveil, guard and alert security personnel to breaches of the perimeter. They are often used with non-conductive fencing. These products include:

\r\n

Infrared and thermal cameras
Security lighting
Silent alarms
Motion detectors

\r\n

What other security options are available for high non-conductive fencing?

\r\n

In addition to threat-specific fence types, there are numerous security options available that can be added to a non-conductive fence. If the non-conductive fencing is being installed at an electric supply station, all metallic elements must be properly grounded and in compliance with the National Electrical Code Safety Committee standards. These would include metallic security components such as:

\r\n

Caution signs
Flood lights
Alarm systems
Spike toppers
Concertina razor wire
Barbed wire

\r\n

What is a ballistic shield?

\r\n

Ballistic shields are engineered to protect people and equipment inside the secured perimeter from gunfire. These panels are made of resin composites and laminated fiberglass. The ballistic projectile initiates a process of energy-absorbing delamination. Protogetic advises you to discuss installation of ballistic shields with security experts and engineers as well as the fence and shield manufacturer.

\r\n

Which non-conductive fence is best?

\r\n

This depends entirely on your project and numerous factors like location, function, threat assessment and budget. There is no one-size-fits-all high security or non-conductive fence. This is why it is vitally important to determine your threat risk.

\r\n

How much do non-conductive fences cost?

\r\n

Suffice it to say, non-conductive fencing is a lot more expensive than run of the mill residential fencing. For exact pricing, you can contact fence manufacturers directly using Protogetic.com’s free, no-obligation “GET A QUOTE” button located on every product page. You can also instantly download specifications, technical drawings and ratings certifications (where applicable).

Penetration Resistant Fences

\r\n

What is a penetration resistant fence?

\r\n

A penetration resistant fence, sometimes called an anti-cut fence, is a type of high security fence designed to prevent or delay breaching by an intruder using tools to cut the fence material and gain entry into a restricted access facility. This requires more robust fence materials than are used in residential fencing. A key characteristic of penetration resistant fencing is the aperture size and spacing of the openings in the infill/fence fabric. Very small apertures that are tightly spaced prevent breaching tools from getting any “bite” or leverage with which to bear down and cut the fence material.

\r\n

Are penetration resistant fences and anti-climb fencing the same?

\r\n

They’re not exactly the same but very similar in that each requires the infill fabric to have very small, tightly spaced apertures. In the case of anti-cut fencing, this prevents or delays breaching using cutting tools. The small apertures also prevent finger and toe holds, making climbing extremely difficult if not impossible.

\r\n

What part of the fence is infill?

\r\n

The Department of Defense refers to fence infill as “fence fabric”. This refers to the fencing material that actually creates the barrier between the panel’s frame posts and horizontal rails. Infill or fence fabric gives the fence its ‘look”. The most popular infill used is chain link because it is easy to install and very inexpensive. That’s great for residential and demark boundary fencing but not for high security, penetration resistant applications. Unless the chain link uses a very strong heavy gauge wire, it will not provide sufficient protection against intrusion. Most chain link can be breached in as little as 7 minutes.

\r\n

However, there are many other infill options that satisfy high security requirements depending on your budget and the aesthetic considerations of your project. To delay or even prevent forced entry, there are several infill options that can be penetration resistant:

\r\n

Welded wire
Wire mesh
Metal screen
Palisade
Expanded metal
Heavy gauge chain link

\r\n

What is the standard for penetration resistant fences?

\r\n

The main standard for high security fences is UFC 4-022-03: Security Fences and Gates. There are several test standards that apply to penetration resistant fences, including:

\r\n

ASTM F2781 -- Standard Practice for Testing Forced Entry, Ballistic and Low Impact Resistance of Security Fence Systems. This is a timed test using a six-crew attacking team armed with various breaching tools.

\r\n

LPS 1175 – this is the Loss Prevention Certification Board’s forced entry standard. Like ASTM F2781, LPS 1175 is a timed attack perpetrated by multiple personnel armed with breaching tools. However, where ASTM requires 6 attackers, LPS 1175 only requires 1, 2 or 3 attackers, depending on the security level being tested.

\r\n

How high should an anti-cut security fence be?

\r\n

Typically, the minimum height for a security fence is six feet. However, many security fences are taller, ranging from 8 feet to 16 feet or more.

\r\n

Where are penetration resistant fences used?

\r\n

Industrial facilities
Military bases
Airports
Oil refineries
Nuclear plants
Chemical plants
LNG terminals
Correctional centers

\r\n

What is a “clear zone”?

\r\n

A clear zone is simply an area around the fence-line or perimeter that provides an unobstructed view to provide easier intrusion detection. Thus, clear zones work in combination with a penetration resistant fence to detect and then delay unauthorized entry into the property so that countermeasures can be initiated.

\r\n

What is security lighting?

\r\n

Security lighting is implemented to assist intrusion detection by making areas visible during the night. Security lighting is just one element of the physical perimeter security strategy and is designed to enhance detection.

\r\n

What are some other security options for fencing?

\r\n

Anti-cut fencing can be paired with intrusion detection equipment such as:

\r\n

Motion detectors
Infrared & thermal cameras
Security alarms

\r\n

What physical deterrents can be added to anti-cut fencing?

\r\n

The following deterrents can be added to the fence top rail:

\r\n

Spike toppers
Barbed wire
Concertina razor wire
Curved Palisades
Ballistic shields

\r\n

High Security Fences

\r\n

What are high security fences?

\r\n

High security fences define and defend perimeters around protected or restricted-access areas by using advanced engineering, design and materials. High security fences also legally define property perimeters (demark boundary) and for specific locations, like military bases or embassies, they are actually required by the Department of Defense (DoD). Such fencing creates an intimidating psychological and physical deterrent against attack.

\r\n

What is perimeter security?

\r\n

Perimeter security encompasses not only high security fencing but also a networked strategy that includes:

\r\n

Security Personnel
Equipment
Access control

\r\n

Why are high security fences important?

\r\n

Given an adequate amount of manpower, time, weapons and tools, no fence is impenetrable. Therefore, the primary purpose of a perimeter security fence system is to delay attacks long enough to increase the probability of detection and institute defensive or evacuation counter-measures.

\r\n

In concert with this priority, high security fences also create the infrastructure needed to install surveillance and perimeter intrusion detection equipment such as motion detectors, infrared, thermal cameras, security lighting, and alarms.

\r\n

What types of high security fences are there?

\r\n

There are several types of fences depending on the threat posed to a facility. Each location might have a different type and level of threat, such as vehicle ramming (called a Hostile Vehicle Attack), physical attack (breaching), small arms fire or even non-aggressor protection for electrical dangers or radar interference. Protogetic highly recommends that a threat risk and vulnerability assessment be performed on Day One of your project.

\r\n

High security fence manufacturers can address your identified security requirements with several protective fence options:

\r\n

Ballistic resistant fence
Non-conductive fence
Anti-ram fence
Climb resistant fence
Penetration resistant fence

\r\n

What rating standard applies to security fencing?

\r\n

The overarching standard is the Unified Facilities Criteria -- UFC 4-022-03 Security Fences and Gates. However, there are numerous fence standards depending on the fence type and material. For instance:

\r\n

ASTM F2780 -- Standard Guide for Design and Construction of Expanded Metal Security Fences and Barriers

\r\n

ASTM F2548 -- Standard Specification for Expanded Metal Fence Systems for Security Purposes

\r\n

ASTM F900 -- Standard Specification for Industrial and Commercial Steel Swing Gates

\r\n

ASTM F1184 -- Standard Specification for Industrial and Commercial Horizontal Slide Gates

\r\n

ASTM F2200 -- Standard Specification for Automated Vehicular Gate Construction

\r\n

What is infill?

\r\n

Fence infill, or “fence fabric as the Department of Defense calls it, refers to the material covering the area that creates a barrier between the fence panel’s frame posts and top/bottom rails. Essentially, infill is what makes a fence look like a fence. Most commonly, this space is filled by chain link. However, there are many other infill options that address more rigorous security requirements as well as the aesthetic considerations and budget of your project. Infill options include:

\r\n

Palisade
Tubular pickets
Chain link
Metal screen
Welded wire
Wire mesh
Fiber rope
Expanded metal
Non-conductive

\r\n

What is chain link?

\r\n

The most common fencing in the world is by far chain link. You see it everywhere, every day. The vast majority of chain link fencing is standard consumer/residential grade and is made from helically wound wire that is then interwoven to create a continuous mesh. Unfortunately, in terms of providing high security, standard chain link provides only about 7- 15 seconds of delay before being breached or completely compromised.

\r\n

That is why there is high security chain link available that uses stronger gauge wires and smaller mesh openings to delay or prevent use of breaching/cutting tools. High security, heavier gauge chain link is obviously more expensive than the kind you buy at big box DIY stores.

\r\n

What is welded wire?

\r\n

Welded wire mesh sounds just like how it’s made – a grid of longitudinal and horizontal steel wires arranged at 90-degree angles are welded together. Compared to chain link, welded wire fencing is stronger and more resistance to penetration or cutting. It is also more climb resistant because the smaller welded wire mesh openings prevent an intruder from gaining a toe or finger hold.

\r\n

Is welded wire the same as wire mesh?

\r\n

No. Welded wire is technically known in the industry as welded wire mesh, which frequently causes confusion with woven wire mesh (too often abbreviated to just wire mesh). While both infill materials get called “mesh”, they are very different.

\r\n

Welded wire uses electric resistance welding to affix the metal wires. Woven wire mesh sounds precisely like it is made – literally weaving steel wires together like a piece of fabric. Another difference, depending on the wire gauge (thickness), welded wire is stronger whereas wire mesh is more pliable.

\r\n

What is expanded metal fencing?

\r\n

Like welded wire, expanded metal fencing also gets its name from the process employed to manufacture it. Numerous slits are cut into a sheet of steel and then mechanically stretched, creating a distinctive pattern of small diamond-shaped openings. These small diamonds are excellent for resisting climbing and cutting, making expanded metal fencing an excellent choice for providing medium and high security.

\r\n

What is Palisade fencing?

\r\n

Palisade fences have been in use for centuries and were sometimes called stake fences because the wooden pales were imbedded in the ground. The stockade forts of the American frontier used this method to create protective walls.

\r\n

The steel palisade fences used today for perimeter security no longer need to bury the pales in the ground. Instead, the pales (much like pickets) are attached to the fence’s top and bottom rails. The pales are extremely strong as they are fashioned from roll formed steel.

\r\n

What security options are available for high security fencing?

\r\n

In addition to threat-specific fence types, there are numerous security options available that can be added to your perimeter security fence system, including but not limited to:

\r\n

Traffic warning lights
Caution signs
Flood lights
Strobe lights
Alarm and loudspeaker systems
Intruder detection equipment
Barbed wire
Concertina razor wire
Spike toppers
Ballistic shield

\r\n

What is a ballistic shield?

\r\n

Ballistic shields are panels made of laminated fiberglass and resin composites. Their design is to absorb the kinetic energy of a bullet by systemic delamination. These panels are attached to the fence to protect occupants inside the fence line.

\r\n

What is barbed wire?

\r\n

Barbed wire is made by twisting two wires into a strand and wrapping very sharp barbs with 2 points (or 4 points) onto it at regular intervals. Barbed wire is most frequently used as a “fence topper” to add an additional and painful deterrent to a would be attacker seeking to scale the fence perimeter.

\r\n

What is concertina wire?

\r\n

Concertina is typically a metal strip of very sharp razor-like points that look somewhat like little butterflies or “X’s”. Concertina wire comes in large coils that can be expanded across the top of the fence. It is often used along with barbed wire for enhanced deterrence.

\r\n

What fence is best?

\r\n

There is no “best fence”. Nor should security be approached with a “one size fits all” mentality. There is, however, the best fence for your project. Protogetic always recommends having a qualified engineer or security professional perform a threat assessment to determine your project’s attack risk. This evaluation examines the building design, location, on-site personnel (military or civilian), threat risk and numerous other factors.

\r\n

What if my project requires a DoD-approved fence?

\r\n

You can instantly find Department of Defense approved vehicle barrier fences on Protogetic’s groundbreaking, 100% digital/searchable, DoD Anti-Ram Vehicle Barrier List.
