Razor Wire History
Originally barbed wire used to create fences around the corral - it was a cheap and effective way to fence large areas, with fairly efficient. Cattle could not overcome barbed wire, wounding thorns and scare away animals. During the first decades of the barbed wire was invited to many structures, which, however, differed only in the design of thorns.
One of the most successful versions of barbed wire was proposed in 1874 by Joseph Gliddenom - this is the construction of barbed wire for a long time produced and used in the Soviet Union. The design was simple and effective - the main wire coils double concertina of the same wire forming with four sharp spines. More robust analog of such barbed wire is used as the basis for the two strands of wire instead of one.
High protective properties of barbed wire is not passed by the military focus, and it became widely used to create obstacles in the conduct of hostilities, the peak of the military use of barbed wire came in the early twentieth century - the First World War. At the time, it created a huge barrier multi-kilometer length and width of a few tens of meters, which have been an insurmountable obstacle, not only for the infantry, but also for the light equipment of the enemy.
During the use of barbed wire were invited to the set designs of barbed wire, one of them - a spiral Bruno. To create such a barbed wire fence wound on a special drum and adjacent turns of the spiral wire is connected to a special scheme. After removal from the drum volume is obtained by barbed wire, which is much harder to overcome than the conventional barbed wire.
Progress does not stand still, and in the middle of the twentieth century, was offered a more efficient design and tech barbed wire - barbed tape razor concertina, which is the basis of springy steel wire of large cross section and steel strip with sharp cutting studs. At first, cutting tape simply wrap around the basics, but then the construction of barbed wire Concertina was further refined - the modern version is a compression of the carrier around the wire cutting the tape, which is practically one with the foundation.
In order to further strengthen the protective properties of barbed wire concertina, it used a well-known in the early twentieth-century way - Spiral Bruno. Like similar structures from the usual barbed wire spiral of razor wire concertina provide high protective properties, which are added to the high strength wire carrier and its spring properties - high quality fabricated and professionally mounted on the facility fence razor spiral is very difficult to destroy or overcome.
Types of razor wire barbed tape causing more severe injuries and more difficult to overcome people without tools, allowing more time for the protection response. Besides the usual scratches and damaged clothes, this obstruction can even kill a person in case of a large loss of blood.
Modern barbed wire, cutting wire, and consists of a metal strip with a blade that is squeezed around the wire. The razor tapes were to twist into a helix. Turns of the spiral in places connected with wire, tape or metal staples.
For the production of the spiral safety barriers, connect the adjacent coils in a checkerboard pattern in the metal flat wire staples or clips. When stretched, the bay spiral security barrier is formed cylindrical prickly fence.
Currently known spiral security barrier in the form of three-dimensional spirals of various diameters and plane security barrier in the form of a flat spiral razor concertina. Razor wire concertina can be made into mobile safety barriers, which are Special Forces stretched on the ground in order to quickly restrict unwanted movement in a certain direction.
It is important that the life of razor wire fence was at a maximum. Therefore, Razor mesh should be made from galvanized materials. The most delicate part of a razor is in need of protection against corrosion, barbed tape. The higher layer of zinc on the barbed tape, the more life thorny entanglements fidget. Usually manufacturers do not report the thickness of zinc on the surface of the razor wire barbed tape, but the Internet can find the results of measurements of the thickness of zinc on the barbed tape from different manufacturers.
