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.

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.
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.
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.
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.
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.
Razor wire is made up of high tensile core wire and a punched steel tape with sharp barbs at close intervals uniformly. The razor tape is cold crimped tightly onto the spring steel core, and finally into rolls for easy transport and deployment. And there are many styles of coils and blades that can be used in different environments. The wire is exceedingly hard to cut utilizing hand devices. While the barbs have a penetrating and grasping activity, reinforced steel makes it difficult to twist.
Barbed wire is fencing wire with pointed barbs at regular intervals along the central wire. It uses a fully automatic barbed wire machine to wrap the barb wire around the main line, which looks like a rope. And barbed wire has three kinds of commonly used twisting methods. Its sharp edge can frighten intruders and thieves, and it is available to combine with other fences for security barriers.

Undoubtedly, razor wire is much more defensive than barbed wire. Closely connected coils, not enough space for people to pass through. Sharp edges and blades can easily cut through people's clothes or skin. It's impossible to cross the barrier of razor wire without enough tools. Compared with barbed wire, razor wire is more dangerous. It's better suited to fences or barriers that prevent people from passing through. For example, it can be used in residential walls, factory fences, military barriers, border walls and so on. Don't use it to protect your livestock, it will hurt them easily.
Barbed wire is often used to build inexpensive fences. Although its protective performance and deterrent power are not as good as razor wire, its manufacturing cost is very low due to its simple manufacturing process and no waste of raw materials. It is a more economical protective fence than razor wire. It's not as dangerous as razor wire, but don't ignore its sharp barb wire. Don't try to cross it unless you want to get hurt. Barbed wire is often used for grassland boundaries, garden protection, livestock protection and so on. Barbed wire is the first fencing technique that can restrain cattle.
Razor wire is commonly used individually as a fence or wall topping for the site and border security. There are several ways of the razor wire installation.
1. It can be installed onto the existing fence systems ' fixed to the top or bottom of the fence with tie wire or barb arms. Such as welded mesh fence, chain link fence, palisade, and ornamental fencing.
2. Installed on top of the brick/concrete wall ' barb arm with flange fasten the razor wire on the brick or concrete wall.
3. To meet the needs of some applications, it can also be installed on the ground along the perimeter. Spread it out directly on the ground to form barrier and separation line.
4. Wed onto frames or attach onto posts as security fencing. Such as welded wire mesh fence.
According to the different operating environment, specially designed brackets should be used to support the razor wire fence
The barbed wire can be used in many places and ways.
Used independently as a fence, barbed wires need to be fixed to fence posts with nails and tie wires. This creates a barbed wire fence. And it can also be fixed to the top of other fences through barb arm and tie wire, like chain link fence, welded wire mesh fencing, diamond mesh fence and so on. After putting the barbed wire on it, the security will be much higher.
Barbed wire fencing is very easy to installation and the speed of installation is very fast. Indeed, even a worker of medium skill can without much of a stretch install such a fencing system. It's important to note that no matter where you install it, you must tighten and straighten the barbed wire.
Barbed wire has fewer raw materials than other fencing products, and its fabrication process is simple. So the cost of barbed wire fence is relatively economical. If you want to surround a large site and don't require too much security, I have to say it is a great idea to use the barbed wire fencing. It will save you a lot of money.
Razor wire is slightly more expensive than barbed wire because of its complex manufacturing process and the waste of raw materials in the manufacturing process. But the wire material and blade material cost less than other kinds of fences if covering same length area. And when you need a big quantity of high-security products, and maybe you have a limited budget for your project, then the razor wire fence is a quite good choice for you.
Maintenance of both products is simple as the fencing doesn't wear out easily if installed properly. And the use of high-quality materials and surface treatment methods can be used for a long time without being corroded. So these two products hardly need to be maintained, just pay attention to repairing areas that may be artificially damaged.
