If you are unfamiliar with the market razor wire security guards, it became a challenge to strengthen the perimeter of the enterprise, institution, or privately owned warehouse. You can easily get lost in the variety of options and features offered in the market. Here are the main characteristics of the razor wire fence, which you should pay attention to.

1- Diameter Of The Razor Wire Concertina

Diameter of the concertina (400 mm, 500 mm, 600 mm, 750 mm, 900 mm) is chosen for each object individually. It is the main parameters. The greater diameter, the higher efficiency when installation. But the greater diameter, the price per meter of the razor wire concertina is higher. Another detail - usually indicated carrying the diameter of the bay. After stretching and setting the diameter of the razor wire concertina decreases. For example a concertina diameter of 500 mm after the installation will have a diameter of 450 mm.

2- Number Of Turns In The Concertina

Number of turns in the concertina can be from 31 to 61. The smaller the number of turns - the concertina easier install, convenient to work with it during installation, but more often have to connect the concertina, and each connection - a place of potential vulnerability.

3- The Length Of The Razor Wire Concertina Coil Stretch

The length of the razor wire concertina coil stretch, is the distance between the adjacent coils, which is proclaimed by sellers in the price lists, often differs from reality. The maximum distance between the turns of the spiral should be no more than 390 mm​​. otherwise, it leads to an increase in distance between the coils, reducing the rigidity of the Concertina, Razor tape losing its protective properties, and consequently to a distortion of the idea of creating high-performance line of defense.

4- Number Of Rivets

Often, taking advantage of ignorance of the buyer, the seller does not specify a firm quantity of cramp (3 or 5) and sells cheap Miniature 3x the price spiral of the more expensive 5-Miniature. It must be remembered that if the use of 3-Miniature bond still valid for small-diameter coils (500 - 600 mm) by reducing the effectiveness of barrier (its stiffness and resistance to snacking), then the coils of large diameter (900 mm), it is unacceptable - the fence is be ineffective.

5- The Quality Of Raw Materials

Galvanized strip thickness must be within 0.5-0.55 mm. Using a thin strip initially has almost no effect on the effectiveness of security fence (fencing down properties - no spikes interlock, and bent), but in the long run reduce the obstacles to service a few times. The guide wire should always be galvanized high carbon with a diameter of 2.4 - 2.5 mm. If the wire without coating, in the near future you will lose the fence. Staves should also be made of galvanized metal. If you use the material without a coating, then the points of contact to begin the processes of destruction, be lost strength and aesthetic appearance.
