Concepts such as technical specifications and GOSTs for barbed wire are, unfortunately, not observed by all manufacturers today, causing conscientious companies to suffer. Before you buy Egoza or Concertina barbed wire, you need to take into account a number of design features, which will be discussed in this article.
As noted above, high-quality barbed wire is always manufactured in strict accordance with GOST and technical specifications. In addition, when purchasing barbed wire, you should also pay attention to such physical indicators as resistance to deformation, level of elasticity, and the presence of galvanized coating. Naturally, all these indicators as a whole fundamentally affect the service life of the product. The galvanized coating of barbed wire allows you not to worry about corrosion, which means that such wire simply does not face physical destruction and loss of functional qualities. For spiral barbed wire, elasticity is also an important criterion for its quality. High elasticity allows the spirals to maintain their shape throughout the entire service life of the barrier. An elastic barrier is more effective in terms of deterrent qualities, and therefore more reliable.
High rigidity of the product is achieved through the use of a wire base made of high-carbon steel coated with zinc. The production of such wire is regulated by GOST 7372-79, GOST 9850-72 or GOST 9389 adopted in 1965. The elasticity of barbed wire is affected by both the raw material from which it is made and the thickness of the wire itself. Even a difference of tenths of a millimeter significantly affects the elasticity of the barbed wire. Thus, a wire with a diameter of 2.8 mm will be much stiffer than a product with a thickness of 2.5 mm. Speaking of practical examples, it is worth mentioning spiral barriers. The larger the diameter of the spiral, the higher the rigidity requirements for the wire. Spirals with a diameter of over 1.5 meters are made of wire with a cross-section of 4 mm.
When purchasing barbed wire, you should remember that it includes such a thing as a warranty period. Galvanized barbed wire concertina.ua can be considered high quality if it has a warranty period of at least 15 years. For high-carbon steel wire, this period is 30 years. The longest warranty period of 50 years is given for barbed wire made only from alloy steel.
