Razor Wire Fence

What is razor wire fence:This can be achieved easily and economically by adding fence toppings of twisted barbed strand wire or razor wire. The razor wire coil can be mounted on the existing fence forms an enhanced new fencing, called Razor Wire Fence. The barbed wire mounted mesh fences are called Barbed Wire Fence. Almost all the mesh fence panel (especially chain link or woven mesh or welded mesh panels) can work with barb or razor tape concertina. Those fence with smooth top rails are more convenient for installing fence toppings with tension wire, clips or Y supports. The sharp razor wire fence is used in military and prison fencing at the beginning, now popularly used for industrial and commercial fencing as perimeter fence, residential steel picket theft-resisting fence and chain link security fences, etc. In this page, we also introduce a case study of How the Chain Link Fence and Gate are Used as Security National Fencing with the Adding of Barbed and Razor Tapes.

What Enables Barbed Wire and Razor Wire to Enhance Existing Mesh Fence to High Security Fence? The special design and physical anti-climbing feature of the barbed wire and razor wire. The twisted barbed wire strand has pointed barbs that will hurt or hold the intruders easily. The razor wire has sharp blade profiles that will cause more severe harms. When they are mounted along the top railings of the metal fences, even the common chain link fences become frightening for the intruders.

Why Choose Razor Wire Fence?

Though barbed wire seems cost less compared with razor wire, we recommend razor tape concertina as security razor wire fence toppings. The latter will give higher security to the existing metal mesh fencing, offers more fencing forms and cost less in view of its higher security level and long term uses in general.

What Advantages Does Razor Wire Fencing Have Over Barbed Wire Fences?

Razor barbed wire fencing and razor wire concertina makes the majority of our products. Razor barbed wire fencing is usually made of galvanized steel blade or stainless steel blade. Two pieces of stainless steel razor wire or zinc-coated razor wire can be bounded together by clips to make it stronger. The spiral intersecting barbed wire presents an intersecting shape after opening with beautiful outlook and practical property
Material for Razor Barbed Wire Fencing: Galvanized blade, stainless steel blade. 
Features: Compact and rational structure, high safety factor, for the protection of prison and key project . 
Technical Note: Razor barbed wire fencing can be made according to the actual dimension of customer; the special specification is manufactured according to the drawing
Standard products are shown in the tables above, special specifications available on request. 
Standard materials are either galvanized or stainless steel.

Barbed wire normally refers to the stranded steel wires with twisted barbs. The galvanized steel barbed wire or plastic coated barbed tapes have short barb and less frightening. The razor wire coils have wide and bigger blades. Secondly, the barbed wire is a kind of strip protecting only a small space. The razor tape can be mounted in crossed concertina coils with bigger covering diameter. Thirdly, the barbed wire can be supplied only in one form, along one direction, while razor wires can be supplied in several forms: flatwrap razor wire, crossed concertina razor wire or blade razor spikes. The different forms of razor wire fence toppings can be mounted to the fence panels to achieve various fencing barrier effects.

Hot Dipped Galvanized Razor Tape Flat Type

Wall and Roof Protection Spikes

What kinds of mesh fence are suitable to work with razor wire? Or where is the razor wire fencing used?
Almost all wire mesh fences welded or woven can be installed with razor wire fence toppings. But it is not always necessary to use razor wires. It is mostly used in military and prison perimeter fencing, also used for perimeter fence for industrial and commercial sites to protect private or public poverties, for high grade residence and villa areas. Razor wire coils can also be individually used in military uses and wars to form a mobile barrier.

Topping Styles for Razor Wire Climbing-Resisting Barrier Systems:

Razor Wire Flat Wrap;
Cross Type Razor Wire Coils: supplied in hot dipped galvanized steel finish or stainless steel 316, helical forms, supported with Y post;
Barb Wire and Razor Tape Concertina Combined Tapes;
Wall Spikes: Used along walls or other flat strips or areas to form a scope of security by stopping people and birds.

Case Study of Chain Link Mesh Razor Wire Fencing:

Anti-Intrusion Perimeter Security Fencing for Land Border of Kuwait. A project using Razor Tape Wire and Barbed Wire as Toppings for CHAIN LINK FENCE and Gates.
General Information: The system is composed with four major parts: Chain link fabrics, barbed wire and razor concertina tape toppings, chain link gates, and fence posts and fittings.
Ministry Of Interior secured its Northern and Southern Land border of State of Kuwait with the Anti Intrusion Perimeter Security Fencing installed for about 465 km and with 2.5 M in vertical height from the ground line to the top line of the barbed wire attached to the extension arms.

Fence has 6 rows of barbed wire and one row of Razor Wire Tape. Therefore, the total Height of the fence including the Razor Tape coil is 2.9 Meter from the Grading level of the ground until the apex of the Razor Tape coil. It also includes, 8 Numbers of Double leaf Main Gates .
