Barbed wire is a defensive metal wire, and the body is covered with a sharp edge, and there is also the same distance between the spikes. It is used for various security fencing and barriers. It can be laid directly on the ground, mounted on the top of fence or in rows as an independent barrier. This type of wire is economic and easy to install.

The barbed wire consists of barb wire and line wire. The wire diameter of line wire is larger. Using the two twisted line wires can improve the quality of fastening studs and prevent the displacement along the wire.On a single strand barbed wire, in order to avoid spikes rotate around horizontal wire, the horizontal wire is made by corrugations and its cross section is not circular.To prevent corrosion, barbed wire has a zinc coating.

Currently, double twist barbed wire been widely used by many countries in military field, prisons, detention houses, government buildings and other national security facilities. Recently years, barbed tape has apparently become the most popular high-class fencing wire for not only military and national security applications, but also for cottage and society fence, and other private buildings.

The sharpened spikes are protective elements of barbed wire. Its high resistance allows greater spacing between the fencing posts. It used for grass boundary, railway, highway isolation protection.
