The barbed wire is something that you will find in almost all enclosures. It is made up of a very flexible steel wire that has sharp barbs. It is the most preferred enclosure material that is used along with hardened steel posts. This type of enclosure is apt for keeping livestock within the section. They also prevents any wild predators from entering the area. As an effective deterrent to the livestock to not venture out of the enclosure, the barbed wire remains the best choice.
The same holds for any wild animal wishing to enter the section to prey on the livestock.The barbed wire initially had its origins within the military setup.
It was found to be very good for use in the outside world as well. After the Civil War, people used barbed wire for broader purposes. Lucien B. Smith first patented the barbed wire. During the days of the Wild American West, many of the cattle ranchers used such wires to protect their livestock by building fences with it.
Its history can be traced back to the days of the Wild American West as mentioned above. It then quickly made its way into Europe after the use in the Civil War and then during the Cold War as well. The wire also played its part during the Vietnam war. The US developed the first patent for its use.
After a modest beginning with its usage as just a fence, the utility value of the barbed wire manifested itself in many other ways. Different types are listed below
The above-mentioned barbed wire types are all made using the process of galvanization. The GI wires used to make them have a zinc coating that renders the wires rust proof and free of corrosion. The process starts with the preparation of a molten bath. The sheets are immersed into this bath to prevent rust. The sheets are then with the help of machines made into different types of wires for various uses.

The barbed wire making machine is used to make them. Two wires are the input that is fed into the machine. They are twisted such that they form a cable.
One more wire is then introduced into the machine from its side and also twisted into these wires. Then the two-point barb is formed by cutting the wire at a specific angle on both the sides.
If four-point barbs are required then two of the wires are twisted and cut.The materials used are typically galvanized steel. The other popular material is the r galvanized high-tensile steel.
These wires are also coated with PE or PVC. The advantage with PVC coating is the different colours you can get for attractive looking fencing to be done. The tensile strength is typically between 30-45 kgs/sq.mm.
One of the well-known companies in the field of manufacture of the GI Wires, Galvanized Iron Wire is the Systematic Group. The company began operations in 2000. It has been an important supplier to diverse industries and across geographic locations. Their products carry the license of BIS or Bureau Of Indian Standards. This conforms to JIS, DIN, BS and ASTM specifications.
