OPTIONS & FEATURES
Modular barrier fence™ are commonly utilized in special high security events at local, state, and federal levels. Temporary high security fencing is required for crowd control and to temporarily close off restricted areas at special events.
Most users and government agencies rely on a combination of concrete barriers and traditional security fencing mounted on top of those barriers. Some end users specify barrier fences for other reasons.
For example railroad companies specify those fences to protect railroad cars in railroad yards instead of traditional security fences. However, Barrier fences eliminate the need of digging near railroad tracks which is not desirable due to space constraints and the presence of underground cabling along the tracks.
The optional DualGuard™ mesh significantly increases the time required to breach the fence. The ASTM F2781-15 Standard Practice for Testing Forced Entry, Ballistic and Low Impact Resistance of Security Fence Systems defines a successful breach if the attacker manages to cut a 2’ x 2’ opening into the fence.
While access to the first mesh is straight forward, access to the second mesh of the DualGuard™ mesh is much more difficult resulting in a significant increase in breach time.
An additional design feature of DualGuard™ is to rotate one mesh by 90 degrees relative to the other mesh which will make cutting those meshes even more difficult.
Tests have shown that the times to breach two meshes mounted a few inches parallel will require at least twice the amount of time required to breach the two meshes individually. This is a true occurrence of 1 + 1 > 4.
CHAMELEON MODULAR BARRIER FENCE™
The Chameleon Modular Barrier Fence™ is an expanded metal barrier fence similar to the design described in the ASTM F2780 guide. However, it has some additional options to add extra security. Besides razor and barbed wire, expanded metal splices from barrier to barrier and an DualGuard™ expanded metal mesh can be added for extra security.
Fence elements are typically connected barrier to barrier with splices across the fence meshes being optional. Also, Fence meshes typically overlap the concrete barrier to prevent a stepping onto the concrete barrier.
ANC MODULAR BARRIER FENCE™
The ANC Modular Barrier Fence™ a non-conductive fiberglass reinforced plastics (RFP) fence is used frequently by the electric power and transmission industry.
Considering that it often takes many years to upgrade a working substation, utilities need a non-conductive fence to eliminate the requirement for electrical grounding of their temporary fence. Other applications are in highly corrosive environments in coastal areas.
AMICO Security offers two highly corrosion resistant finishing options:
- Hot-Dip Galvanizing
- AMICOAT™ Powder coating over E-Coating or primer
All of AMICO Security’s finishing processes involve a zinc layer for superior corrosion protection. Corrosion is an electro-chemical process caused by an electrical potential between two small areas of steel, anodes and cathodes, and an electrolyte.
Additionally, The electrolyte, most often water, starts the corrosion reaction by connecting the anode and with the cathode resulting in iron oxide, which is the brown, flaky rust typically seen on unprotected steel.
While a traditional paint layer aims to prevent water from touching the steel, a zinc layer provides a superior cathodic protection replacing the steel anode with a zinc anode resulting in zinc oxide which forms a protective layer instead of rust.
