Concertina Wire, also known as "snake belly" wire, is a type of barbed wire that is widely used for security and fencing purposes. It is made from high-quality steel wire, which is then twisted into a spiral shape, resembling the belly of a snake, hence the name. The wire is often coated with a layer of zinc or plastic to enhance its durability and resistance to corrosion.

One of the key advantages of Concertina Wire is its high level of security. The sharp barbs make it difficult for intruders to climb or pass through, providing an effective deterrent against unauthorized access. Additionally, the wire is flexible and can be easily installed on various types of fences or barriers, making it a versatile security solution.

Concertina Wire is available in a range of sizes and specifications to suit different applications. Common dimensions include a wire diameter of 2.0-3.0mm and a coil diameter of 30-60cm. The wire can be supplied in rolls or individual coils, depending on the customer's requirements.

Installation of Concertina Wire is relatively straightforward. It can be attached to existing fences or barriers using clips or brackets, or it can be strung between posts to create a new barrier. The wire can be installed at varying heights and densities, depending on the level of security required.

Some common application scenarios for Concertina Wire include military installations, border control, prisons, industrial facilities, and residential properties. It is also used in wildlife control, as the sharp barbs can deter animals from crossing the fence.

In summary, Concertina Wire is a highly effective and versatile security solution that offers a range of benefits, including high security, durability, and ease of installation.
