When there is a need for heightened security, it is critical to choose the right fencing solution. Twinbar fencing, also sometimes referred to as double wire fencing, is often the preferred option for high-risk sites. Featuring a unique design of vertical wires with two horizontal wires welded on top, this distinctive fencing solution offers numerous benefits for a variety of critical infrastructures due to its inherent tamper resistance, tremendous strength, and durability.
Why Double Wire Fencing Is the Preferred Choice for Sensitive Facilities
Enhanced Physical Security
Twinbar fencing is constructed with two horizontal wires and vertical wires that run parallel to one another. These wires are spaced precisely apart from one another in a mesh design that resists climbing, cutting, and ramming. As a result, it is much more difficult for double wire mesh fencing to be breached compared to single-wire chain link fencing. In fact, tests have shown that this type of fencing can resist a bolt cutter for as long as four minutes and is even capable of withstanding as much as 1,500 pounds of pressure per foot.
At every intersection in twin wire fencing, welded joints ensure the intersections cannot be spread apart or loosened. Prospective intruders often take advantage of any possible weak points or hidden gaps in other types of fencing. There are no such vulnerabilities in twin wire fencing.
Vehicle-Resistant
Another area where standard fencing often fails is the ability to stop heavy vehicles moving at highway speeds. Since double wire mesh fencing is designed for high impact, it often performs very well in crash ratings. For this reason, twin bar fencing is an ideal choice for government compounds, military bases, power plants, refineries, or any other critical infrastructure where valuable assets are a concern.
Climber-Resistant
The dual horizontal and vertical parallel wire construction of twin wire fencing offers a greater level of strength than traditional fencing. The way in which these wires work together creates a much stronger setup. An attacker trying to gain access to a facility will find that there is nowhere to gain a grip on the flat surface.
Cut-Resistant
One of the drawbacks of traditional fencing is that it is far too easy for an intruder to gain access by simply using bolt cutters to slice through the fencing. This is not the case with double wire fencing. Even if an intruder were able to cut through the fence’s horizontal wire, the vertical wire would still be present. It would take several cuts to gain access through even a small portion of the fence.
Improved Surveillance Visibility
Real-time monitoring is made possible thanks to the open design of twin wire fencing. This allows for far greater visibility for patrols and security cameras while also offering faster threat detection.
Corrosion-Resistant
Double wire mesh fencing is constructed from high-tensile galvanized steel. The addition of protective coatings improves the resistance to corrosion and rust in twinbar fencing compared to standard fencing. This becomes particularly important in both industrial and coastal environments, where corrosion and rust are frequent concerns.
Demonstrated Effectiveness
Case studies have shown that twin wire fencing significantly reduces break-in attempts and attempted cut breaches. Other studies have shown that after double wire mesh fencing was installed in some locations, there were no physical breaches at all.
Ease of Installation
Twinbar fencing also offers tremendous ease of installation. We can usually install this type of system both quickly and efficiently. In cases where it is necessary to install a reliable fencing system in a high-security site with no delay, double wire fencing is the proven choice.
Environmentally Friendly
Twin wire fencing is coated using an architectural-grade polyester powder coating system. Not only does this system offer the greatest level of durability and high-color reliability for many years, but it also translates to a more environmentally friendly option since there are no solvents used in the coating system.

While double wire mesh fencing is an appropriate solution for any type of sensitive facility, there are certain types of sites where such fencing is the ideal choice. These include:
- High-Risk Commercial Sites – Technology campuses, public transit, and airports
- Government and Military Installations – Intelligence centers, missile silos, military bases
- Correctional Facilities – Jails and prisons
- Critical Infrastructure – Water treatment facilities, power plants, oil and gas refineries, telecom hubs
- Educational Facilities – Schools, universities
- Sports Venues
Common Questions About Double Wire Mesh Fencing
Is it possible to combine double wire mesh fencing with electronic detection?
The rigid structure offered by twin wire fencing makes it the perfect choice to integrate perimeter intrusion detection systems. For example, we can securely mount detection cables, taut wire systems, and vibration sensors directly on the fencing. The rigidity of the fencing assists in reducing false alarms while also providing enhanced data for intrusion location.
How long does double wire mesh fencing last?
When properly installed, a twin wire fence system will probably last for at least 20 years with only a minimum amount of maintenance in most environments. Such enhanced longevity translates to a lower cost of ownership.
Are there customization options available for double wire fencing?
In some cases, customization options are available for double wire fencing. Such options include wire diameters, panel heights, mesh opening sizes, widths, and coating colors and types. Additionally, it is often possible to customize the integration of specific topping systems and posts for double wire fence solutions.
