Concertina coil barbed wire sample

We manufacture razor wire in concertina coils or straight razor lines. Concertina coils include single, double, and across spiral shaped coils. It is made of galvanized barbed tape and high tensile galvanized core wire, which form continuous spiral razor wire. We use galvanized materials to prevent corrosion. And all materials have been strict quality tested to ensure razor concertina products strength and efficiency. The coils can be collapsable for easy transportation, and can be easily retracted and stored vertically or horizontally.

Concertina coils are usually installed on the top of chain link fence, welded wire fence or walls, on the ground or at the bottom of fencing. It forms a uncrossable barrier called concertina coil fencing. Often a line of barbed wire runs across the concertina coil fencing. This type fence is ideal security fencing with great anti-climb and anti-cutting property, and has very high security, strong and durable features. It is widely use in garden, school, prison, military sites and airport for effectively protecting these areas from external invasion threats.
