Barbed Wire Multiple Classification Protecting Sites and Farms

Barbed wire, also called barb wire, bob wire and bobbed wire. is the most important component of barbed wire fence system, here are several data for your easy choice and reference.

Materials of barbed wire

Barbed wire can be manufactured from various material, different materials of barbed wires have their own characters, you should choose the suitable materials according to your specified application and using environments.

• Galvanized barbed wire. Galvanized steel wire material is the most widely used type in not only the barbed wire production, but various wire mesh fence panels production. It can supply excellent corrosion and rust resistance performance to be used in the high corrosive and other harsh environments. It can be divided into different types according to different standard.

• According to the technology

• Electric galvanized.

• Hot dipped galvanized.

• According to the standard

• Commercial type.

• Class 1 galvanized.

• Class 3 galvanized.

• Zinc-aluminum barbed wire. This type alloy wire mainly contains zinc and aluminum element. According to different composition, it has 5% aluminum-zinc alloy wire, which is known as the Galfan wire and 10% aluminum-zinc alloy wire. Compared with traditional galvanized wire, it can supply double to triple times corrosion resistance performance. It is more and more widely used in the barbed wire productions.

• PVC/PE coated barbed wire. Low carbon steel wire or galvanized steel wire are attached with PVC or PE forming the PVC/PE coated wire. The PVC coated steel wire can also supply excellent corrosion and rust resistance performance, especially the PVC coated steel wire with galvanized inner wire, which can supply double protection for the barbed wire. The PVC coated barbed wire can be made into various colors to decorate the sites and blend with surrounding environments. The most widely used color is green, we can also customize any colors based on the RAL colors and your requirements.

• Stainless steel barbed wire. As we all known, the stainless steel is the most durable material among all the steel wires. It has best corrosion and rust resistance and good chemical and physical properties to be used in various applications. It is suitable for the applications, where needs high grade corrosion resistance requirements and beautiful and bright surface.

Strand structure of barbed wire

he barbed wire can be divided into single strand barbed wire and double strand barbed wire.

• Single strand barbed wire. It has the simplest structure, which contains single strand and barbs. Compared with the double strand barbed wires, it is much more economical and lighter weight. It is suitable for the common applications. But it is easy to destroy and cut, so it is not suitable for heavy duty applications.

• Double strand barbed wire. It is formed with two strand wires (line wires). The barbs are twisted between of the two wires and fastened onto the line wire. The double strand barbed wire can supply higher tensile strength to prevent cutting or destroying. It is suitable for the heavy duty applications, such as prisons, military sites and other places.

Barb structure of barbed wire

Barbs are very important for the barbed wire. The strong barbs with sharp points can resist bending. It can frighten and defend thieves and intruders. They can also contain your animals and livestock safely in your farm or ranching. The barb can be single or double wires for different applications.

• Single barb. Also known as 2-point barbed wire. It is contains single barb wire twisted on the line wire. The single barb wires is used in the common applications. Or if your farms or pens has enough space for rearing animal or livestock, you can choose the single barb (2-point) barbed wire.

• Double barbs. It is also called 4-point barbed wire. Use two barb wires twisted together onto the line wire. It can supply greater hurt factor for your sites or ranching. It is widely used in the heavy duty applications. Or if your farms or ranches has a herd pressure, you can choose the 4-point barbed wire.

Twist style of barbed wire

As we all know, the double strand barbed wire is made of two high quality steel wire and then twisted together to form a higher strength and more rigid structure. It can be divided into traditional twist and reverse twist according to different twist direction.

• Traditional twist barbed wire. In the barbed wire production, commonly, the steel wires are twisted in single direction, which is the traditional twist. This type barbed wire has a simple structure and the barbs are positioned and twisted between the two line wire. The traditional twisted barbed wire is suitable for all common applications.

• Reverse twist barbed wire. Reverse twisted barbed wire refers to the steel wires are twisted in the opposite direction and the barbs are positioned and twisted outside of the two line wire. Compared with traditional barbed wire, the reverse twist barbed wire can supply high tensile strength and breaking strength. It is a bit more expensive than the traditional twist barbed wire and it is suitable for the heavy duty applications to withstand the high impact from external.

Applications of barbed wire

Barbed wire has two main applications:

• Used in farms and ranch for rearing livestock. It is an alternative to the woven wire field fence and electric fence. Different spec and structure can keep your cattle, horse and other livestock in the area and prevent them from walking or climbing out of the pens.

• Barbed wire used for security application.

• Barbed wires can be used individually to form the barbed wire fence on the highway, railway and other dangerous places to protect site and people' safe.

• It can also be attached onto various wire mesh fences to improve the security factor of the site, such as prison, factory, military sites, airport and other places.
