Concertina fence is a high-security barrier composed of razor wire. When expanded, it forms large coils that can stretch like a spring. When compressed, the coils nest within each other. This type of fence, designed for perimeter security, consists of interconnected coils of barbed or razor wire attached to a fence structure. The concertina wire is stretched and anchored between posts, creating a formidable barrier.

Concertina fences are designed to deter and prevent unauthorized access due to the sharp blades or barbs present in the wire. They are often used in high-security areas such as military installations, prisons, airports, and border barriers because of their efficacy as a physical deterrent.

The fence can be deployed on the ground as a barrier or placed atop walls and fences to increase the difficulty of scaling them.

Concertina fences are commonly used in military installations, prisons, border security, and other high-security areas where enhanced perimeter protection is required. The main features and benefits of concertina fences include:

Security: The presence of concertina wire on the fence acts as a strong deterrent against unauthorized access and intrusion. The sharp barbs or razor blades make it difficult for individuals to climb over or cut through the fence.

Durability: Concertina fences are typically made from high-tensile steel wire that is galvanized to resist corrosion. This ensures their durability and longevity, even in harsh outdoor environments.

Versatility: Concertina fences can be installed as standalone barriers or integrated with existing fences or walls. They can be customized to suit specific security requirements and site conditions.

Visual deterrence: The presence of concertina wire on a fence serves as a clear visual warning to potential intruders, indicating the high-security measures in place.

Easy installation: Concertina fences can be relatively easy to install, depending on the site and application. They can be mounted on posts or brackets and tensioned to create a taut and effective barrier.
