Concertina Barbed Wire with Chain Link Fence for High Security

Concertina barbed wire has only one strand line wire with many small protrusions on the surface to prevent barbs sliding, which is the most important component of barbed wire fence system. Concertina barbed wires can be used individually to form the barbed wire fence, and they can also be attached onto various wire mesh fencing, such as chain link fence, welded fence or expanded metal fence to achieve high level security. With the features of sharp edge, high quality, stability, rigidity and corrosion, rust resistance, they are widely used for airport fencing, factory fencing, farm fencing, river fencing and so on.

A section of concertina barbed wire has only one strand line wire with many small protrusions on the surface which is connected with clips and each twist barb has four spikes.
