long Barb Razor Wire Coil Fencing Corrosion Resistant 450mm Diameter

Barbed tape or razor 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. Razor wire is much sharper than the standard barbed wire ; it is named after its appearance, but is not razor sharp. The points are very sharp and made to rip and snag clothing and flesh.

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. Razor wire is used in many high-security applications because, although it can be circumvented relatively quickly by humans with tools, penetrating a razor wire barrier without tools is very slow and difficult, giving security forces more time to respond.

Construction

Razor wire has a central strand of highsile 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. Flat barbed tape is very similar, but has no central reinforcement wire. The process of combining the two is called roll forming.

Types

Like barbed wire, razor wire is available as either straight wire, spiral (helical) coils , concertina (clipped) coils, flat wrapped panels or welded mesh panels. Unlike barbed wire, which usually is available only as plain steel or galvanized, barbed tape razor wire is also manufactured in stainless steel to reduce corrosion from rusting . The core wire can be galvanized and the tape stainless, although fully stainless barbed tape is used for permanent installations in harsh climatic environments 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 12-mm long, medium barb tape has barbs 20-mm to 22-mm long, and long barbtape has barbs from 60 to 66-mm long.

According to the structure

Helical type: Helical type razor wire is the most simple pattern. There are no concertina attachments and each spiral loop is left. It shows a natural spiral freely.

Concertina type: It is the most widely used type in the security defense applications. The adjacent loops of helical coils are attached by clips at specified points on the circumference. It shows an accordion-like configuration condition.

Blade type: The razor wire are produced in straight lines and cut into certain length to be welded onto the galvanized or powder coated frame. It can be used individually as security barrier.

Flat type: A popular razor wire type with flat and smooth configuration (like olympic rings). According to different technology, it can be clipped or welded type.

Welded type: The razor wire tape are welded into panels, then the panels are connected by clips or tie wires to form a continuous razor wire fence.

Flattened type: It is an transformation of single coil concertina razor wire. Flatten the concertina wire to form the flat type razor wire.

Accordign to the coil type

Single coil: Commonly seen and widely used type, which is available in both helical and concertina types.

Double coil: A complex razor wire type to supply higher security grade. A smaller diameter coil is placed inside of the larger diameter coil. It is also available in both helical and concertina types.

Common specifications of razor wire

Package:
1> Per coil Razor Barbed Wire be packed waterproof paper inside with woven bag outside. Then 50 coils or 100 coils be a bundle with steel strip. Or as customers’ requirement to pack to pallet or carton box.
2> Razor Barbed Wire can be loaded to containers in bulk( that is one by one), but this package will lose the quantity for one container.
3> Also has customers’ request there are no waterproof paper inside. Only just let the Razor Barbed Wire be packed with woven bag then several coils Razor Barbed wire to pallet.
