Cheap - Not Always Well
When we want to buy razor wire fence, should we choose the high price one or the low quality one? Generally, the price of good quality razor wire is higher; the price of low quality razor wire is cheaper. In this article we will try find the difference between the high quality razor wire and the low quality razor wire.
What is the difference between the high quality razor wire and the low quality razor wire? Our products are designed for those who think their money. Typically, buyers interested in security fences as there is one meter or one-ton harbor razor and not ask questions about the service life of the facility and especially about its effectiveness.
For example, suppose that in order to protect the perimeter of the object required 100 000 for the purchase of barbed wire, the low quality razor wire. On the fence installation will be spent and about 100 000. The total cost is 200 000. The service life of low quality razor wire is no more than 4 years. 200 000 divided by 5 years and we get 40 000 a year.
If you are using to protect the same object high quality razor wire required 200 000 for the purchase of proper security fence. At installation will be spent and 100 000 (we will not take into account that our razor will want to work for a more rigid, stiff wire core). The service life of the razor fence is at least 25 years. 300 000 will be divided by 25 years and we get 12 000 a year. And whose production is cheaper?
But why the high quality razor wire fence is a long-lasting? First and foremost, is to use only high quality galvanized materials. Thus, the metal of the punched tape has a zinc coating 150 g / m2, while the cheaper metal coating of 50-100 g/m2.

But not only depends on the service life of galvanized steel security fence. Zinc coating effectively prolongs the life of razor wire. The main thing that affects the efficiency and longevity of spiral fence reinforced with barbed tape is elasticity and resistance to deformation. When a mechanical force to the razor wire coil, razor wire concertina should not wrinkle, but should restore its original shape. This is achieved by using as the basis of high carbon galvanized wire with a diameter not less than 2.5 mm (as opposed to cheap razor wire, where applicable wire diameter of 2-2.2 mm, besides a cheap low-carbon). The product will be better, if the wire diameter is larger. Increasing the diameter of the core wire of 2.5 mm to 2.65 mm increases the obstructive properties of the product. For reasons of price-quality, we use to manufacture fencing wire diameter of 2.5 mm.
Significant impact on the quality of razor wire coil has a thickness profile and galvanized strip. Typical for the low quality razor wire tape thickness - 0.4-0.45 mm, which is very small. If you try to overcome such barriers do not engage studs strip the clothes the offender, but merely bent, making it pointless to install fencing itself. We use for razor wire coil galvanized steel tape no thinner than 0.55 mm. Profile of the low quality razor wire is a small spikes at long intervals, which allows greatly reduce the carrying amount of the coils and upload the same amount more of them, but the protective properties of such a tape is much worse than our razor wire.
Another important detail in the production of spiral guards is staples, which connect adjacent pairs of spiral turns in a circle at equidistant points. Razor wire concertina diameter of 900 mm with five straps, and 42 turns in the bay can be set at 9-10 meters, while the coil diameter of 900 mm with three clips and 42 turns in the bay can stretch up to 12 meters. Cost of high quality razor wire and low quality razor wire differs slightly, but the quality is completely different. The high quality razor wire improved fencing properties, as well as appearance and durability.
