1. Structure:

Barbed wire is made of thin iron or steel wire, usually with regularly spaced barbs. These barbs can be single or double, arranged in a spiral or staggered pattern to ensure their protective effect.

The shape of the barbs can be serrated, pointed, or twisted loops.

Typically, two or three wires are interwoven, with the barbs fixed to one of the wires, forming spaced protrusions.

2. Function:

Protective function: The main function of barbed wire is to prevent unauthorized personnel from entering a specific area. It is often used in fences, borders, military bases, prisons, and other places.

Deterrent effect: The barbs not only physically prevent crossing but also psychologically deter, increasing the difficulty of crossing.

High security: Compared to ordinary wire mesh or fences, barbed wire offers higher security and is difficult to cut or climb over easily.

3. Material:

Galvanized steel wire or stainless steel wire is commonly used. These materials prevent rust and increase durability.

Sometimes, plastic-coated steel wire is also used to increase corrosion resistance and reduce the risk of injury from the barbs.

4. Installation Method:

Barbed wire can be installed on fences, walls, or posts, usually fixed with steel hooks or clamps.

It can also be stretched over a larger area to form a robust fencing system to prevent climbing and crossing.

Double or multi-layer barbed wire: More wires and barbs are added to increase resistance.

Electrified barbed wire: Equipped with an electric current to increase the deterrent effect of electric shock.
