Barbed tape or razor wire is a mesh of metal strips with sharp edges whose purpose is to prevent passage by humans. While razor wire is much sharper than the of standard , it is not actually sharp. Even so, the multiple bladed edges of a razor wire fence are designed to inflict serious cuts on anyone who attempts to climb through one, and therefore have a strong effect. In high security applications, barbed tape supplanted barbed wire, which could be circumvented relatively quickly by humans without tools.Types Like barbed wire, barbed tape is available as either straight wire or concertina wire. Unlike barbed wire, which usually is available only as plain steel or , barbed tape is also manufactured in stainless stellto prevent the points from rusting to bluntness. Typically the core wire is galvanised and the tape is stainless, although fully stainless barbed tape is used for expensive permanent installations or usage. Features Barbed tape is also characterised by the shape of the barbs. Although there are no formal definitions, typically short barb barbed tape has barbs from 10 mm to 15 mm long, medium barb tape has barbs 20 mm to 25 mm long, and long barb tape has barbs from 60 to 66 mm long.There does not seem to be much available research to indicate whether longer barbs are actually more effective in resisting penetration, but they provide a stronger psychological deterrent.Reference Number
