Concertina Razor Wire
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 contains a core hardened steel strip that is often under tension, so if cut, it strikes the cutter.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.Like barbed wire, 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 is also characterized 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.Features: •Easy and quickly installation•Low cost than the fence that with post•More security than barbed wireTechnical:General type Razor blade typeBTO-12, BTO-15, BTO-22, BTO-30, CBT-25, CBT-60, CBT-65 Blade thickness:0.5±0.05mm, 0.6±0.05mmWire dia.:2.5±0.1mmBarb length:12±1, 15±1, 22±1, 30±1, 25±1, 60±1, 65±1Barb width:15±1, 16±1, 18±1, 21±1, 32±1Barb spacing:26±1, 33±1, 34±1, 45±1, 40±1, 100±2USE Type A - Concertina razor wire Outside dia.:450, 500, 600, 700, 800, 900, 960, 980mmNo. Of loops:33, 56Standard length per coil:7m to 16mClips:Single coil (without clips), cross type (with clips)Accessories:•Clips Packing:Concertina razor wire single coil: carton packing;Accessories: Carton box;
