In some parts of the world, chain link fence is still installed as a security fence. However, in many regions (including here in Phoenix, Arizona), a chain link fence is not considered a security fence at all. If you’ve ever wondered why that is, this article is for you.
Let’s take a closer look at the answers to the question of what the difference is between a high-security fence, a chain link fence and which one might be best for your project.
What Is a High-Security Fence?
The first thing we need to establish to answer what the difference is between a high-security fence and a chain link fence is to define what a high-security fence actually is.
In the fence world, “high-security” can mean specialized materials or advanced designs that are more resistant to scaling, cutting, and tampering. Rather than being a single, standardized product, high-security fence systems come in many variations, each with its own specifications. Often, these systems include more robust metal components or tighter mesh apertures to eliminate hand and footholds. They’re also commonly paired with enhancements such as razor wire, barbed wire, electric deterrents, or detection systems to warn security personnel of any attempted breaches.
It’s important to note that no fence or wall is totally impervious to intrusion. Human ingenuity can defeat just about anything if given enough time. The goal of a high-security fence is to make attempted breaches as difficult, lengthy, and noticeable as possible.
Time and Difficulty
One defining feature of a high-security fence is that it takes much more time and effort to get through. Heavy-duty materials usually cannot be cut with basic hand tools, so would-be intruders would need to bring specialized equipment. That often means more noise, sparks, and disruption—none of which are ideal if someone is attempting to break in covertly.
Additionally, many high-security fences include elements meant to prevent climbing. Palisade fences, for example, use vertical steel pales with no easy handholds. In the case of 358 welded mesh systems (sometimes referred to as “prison mesh”), the small gaps do not allow fingers or toes through. Climbing aids like ladders can still be used, but bringing a ladder to a fence creates attention and may also be complicated by barbed wire or anti-scale toppings.
Ultimately, high-security fence systems are all about buying security teams extra time to detect and respond to any breaches.
Can a Chain-Link Fence Be a High-Security Fence?
Many people wonder whether a chain link fence can be classified as a high-security fence. Under most common specifications—like those you might see at hardware stores—chain link fence is not typically considered high-security. The large mesh openings are easy to climb, and the metal gauge can often be cut with relatively simple tools.
However, if you increase wire gauge, select a smaller “mini mesh,” bury part of the fence underground or install a concrete apron, and top it with barbed or razor wire, you can create a much more formidable barrier. Integrating monitored electric or taut-wire detection systems can also greatly enhance security. In this scenario, a chain link fence could become an effective high-security system.
It’s important to keep in mind, however, that adding these features to a chain link fence does increase the cost substantially. Since many people choose chain link in Phoenix or elsewhere for its affordability, it might be more cost-effective to invest in a fence designed from the start with security features in mind. A professional fence contractor can help you compare the pros, cons, and costs of different fence types.
Consulting with experts will ensure your fence choice meets local safety requirements and building codes, especially if it’s for a commercial or industrial property with specific security standards. In certain parts of the Valley, more robust fencing might be necessary to comply with regulations for high-risk facilities.
