barbed tape wire is a kind of modern security fencing materials fabricated with razor-sharp steel blade or stainless steel blade and high-tensile wire. Barbed Tape can be installed to achieve the result of frightening and stopping to the aggressive perimeter intruders, with piecing and cutting razor blades mounted at the top of the wall, also the special designs making climbing and touching extremely difficult. The wire and strip are galvanized to prevent corrosion.currently, barbed tape has 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.
barbed tape wire is a mesh of metal strips with sharp edges whose purpose is to prevent passage by humans. The term "razor wire", through long usage, has generally been used to describe barbed tape products. While razor wire is much sharper than the standard barbed wire, it is not actually razor sharp.the multiple blades of a razor wire fence are designed to inflict serious cuts on anyone attempting to climb through and therefore have a strong psychological deterrent effect. In many high-security applications, barbed tape supplanted barbed wire, which could be circumvented relatively quickly by humans with tools, while penetrating razor wire barriers without tools is very slow and difficult, giving security forces more time to respond.
Razor-wire has a central strand of high tensile strength wire, and a steel tape punched into a shape with barbs. The steel tape is then cold-crimped tightly to the wire everywhere except for the barbs. Barbed tape is very similar, but has no central reinforcement wire. The process of combining the core wire with the steel tape was invented by the current owner of Razor Wire International, Renne Cano. The process of combining the two is called roll forming.barbed tape is available as either straight wire or spiral concertina wire. Unlike barbed wire, which usually is available only as plain steel or galvanized, barbed tape is also manufactured in stainless steel, to prevent the points from rusting to bluntness. Typically the core wire is galvanized and the tape is stainless, although fully stainless barbed tape is used for expensive permanent installations or under water.
Barbed tape was first manufactured by Germany during World War I, as an expedient measure during a shortage of wire. Since it was simply punched out of a rolled ribbon of steel tape, it could be manufactured much more quickly. This early barbed tape had triangular barbs and no reinforcing wire; consequently, it was more difficult to cut with ordinary wire cutters, easier to cut with shears, and was generally of lower tensile strength.from the early 1970s, unreinforced barbed tape was commonly used in perimeter barriers of US prisons. In the early 1980s, several manufacturers began offering barbed tape with an embedded reinforcing wire and the product has been the subject to a patent dispute. Early brand names of reinforced barbed tape included "Man Barrier" and "Razor Ribbon". The latter probably lent its name to the modern slang term.
