Concertina wire, often simply referred to as "concertina" or "razor wire," is a type of coiled barbed or razor wire used as a high-security fencing barrier. It is designed to prevent passage and is characterized by its large coils that can expand and contract, resembling the bellows of a concertina musical instrument.

The wire consists of sharp blades or barbs that are positioned at intervals along the coil. Due to its sharp and menacing appearance, it acts as both a physical barrier and a psychological deterrent, making it challenging and dangerous for someone to try to climb over or cut through.

Concertina wire is commonly used in high-security areas like military installations, prisons, and border fences. It can be deployed directly on the ground to create a barrier or mounted atop walls and other fences to increase their security.

Concertina wire is a type of high-security fencing material that consists of multiple interconnected coils of barbed wire. It is named after the musical instrument "concertina" due to its accordion-like shape when stretched out. Concertina wire is commonly used to create temporary or permanent barriers in military, security, and perimeter protection applications.

The main features and uses of concertina wire are:

Security: Concertina wire is designed to create a formidable physical barrier, with the sharp barbs acting as a deterrent against unauthorized access and intrusion.

Easy Installation: Concertina wire is relatively easy to install and can be quickly deployed as a temporary barrier. It can be attached to existing fences, walls, or structures using brackets, stakes, or other mounting methods.

Flexibility: Concertina wire can be easily stretched out and retracted when needed. It is highly adaptable and can be used for both permanent and temporary security installations.

Durability: Concertina wire is typically made from high-tensile galvanized steel, which provides excellent strength and corrosion resistance. This ensures its longevity and effectiveness even in harsh outdoor environments.

Versatility: Concertina wire comes in various configurations, including single coils, double coils, or flat panels. This allows for customization based on specific security requirements and installation needs.

Visual Deterrence: The presence of concertina wire serves as a visual deterrent, warning potential intruders of the security measures in place.
