How to Choose Razor Wire?

Reinforcing the perimeter of a business or private warehouse can be a challenge if you are not familiar with the barbed wire security available on the market. Here are the main features of razor wire that you should be aware of.

1. Quality of the raw material

The thickness of the galvanised strip must be between 0.5 and 0.55 mm. The use of thin strips initially has little effect on the effectiveness of the security fence (fence down properties - no spike interlocks and no bends), but in the long run reduces service barriers several times. The wire should always be galvanised high carbon steel with a diameter of 2.4 - 2.5 mm. If the wire is not coated, you will lose the fence in the near future. The slats should also be made of galvanised metal. If you use uncoated material, the contact points will begin the process of destruction, losing strength and aesthetics.

2. Diameter of the razor wire concertina

Choose the concertina diameter (400 mm, 500 mm, 600 mm, 750 mm, 900 mm) individually for each object. It is the main parameter. The larger the diameter, the more efficient the installation. However, the larger the diameter, the higher the price per metre of the razor barbed wire. Another detail - the diameter of the carrying bay is usually indicated. After stretching and fixing, the diameter of the razor wire decreases. For example, an accordion with a diameter of 500 mm will have a diameter of 450 mm after installation.

3. The number of turns of a concertina

The number of turns of a hexagonal concertina can range from 31 to 61. The smaller the number of turns - the easier the accordion is to fit and the easier it is to use during installation, but more often the concertina needs to be attached, and each connection - a potential loophole in place.

4. Number of rivets

It must be remembered that if the use of 3-Miniature adhesive is still effective for small diameter coils (500 - 600 mm) by reducing the effectiveness of the barrier (its stiffness and resistance to galling), then the larger diameter coils (500 - 600 mm) are still effective. 600 mm), then the larger diameter (900 mm) coils), this is unacceptable - the fence is ineffective.

5. Razor wire concertina coils stretched to length

The length of razor wire concertina coil stretch, which is the distance between adjacent coils, as claimed by the seller in the price list, is often different from the reality. The maximum distance between spiral coils should not exceed 390 mm. Otherwise, it will lead to an increase in the distance between coils, reducing the stiffness of the Concertina and the Razor tape losing its protective properties, thus distorting the idea of creating a high performance defence.

6. Manufacturing techniques

You should carefully monitor the quality of the razor barbed wire tape. The tape should be pressed tightly against the guide wire without gaps. The surface tape after crimping should not bruise (strain) the galvanised surface, which often happens due to imperfections in production equipment (depreciation stamps) or processes. For the same reason, the sharpness of the spine depends on the tape.
