Large rolls of galvanized wire in oxygen violently extinguished, spark, and sodium block, magnesium strip in oxygen extinguished, no spark phenomenon. This phenomenon is determined by the composition of galvanized wire. The galvanized wire used in the experiment is pig iron or steel wire, pig iron and steel are iron and carbon alloy, containing iron and carbon two elements of complex material. Carbon in galvanized wire will produce carbon dioxide when extinguished, solid into gas, volume will shrink rapidly.

The amount of zinc on the surface of high zinc barbed rope is about 5 times that of general zinc barbed rope, thus greatly prolonging the time of rust resistance. In the appearance of the two products are silver white and metal texture is better, for the distinction between the two products is more difficult to distinguish if it is a layman, but for long-term work of professionals can be separated from the two at a glance.

Heavy hexagonal net is made of low carbon steel wire galvanized large wire braid, the tensile strength of the steel wire is not less than 38kg/m2, the diameter of the steel wire can reach 2.0mm-3.2mm, the surface of the steel wire is usually protected by hot dip galvanizing, the amount of galvanizing can reach 500g/m2.

Barbed wire even in the mining industry also has a higher embodiment, because the selection of low-carbon materials to make it has a general iron mesh does not have the flexibility, determined its plasticity in the use, and then can be used in hardware crafts in the deep processing production, as the wall plastering, inside leak prevention crack and so on. Its light net body, the lower cost, can let the customer realize its economic benefits.

In addition to storz and instantaneous couplings, there are also threaded couplings, which feature male and female threads that screw together to create a tight seal. Threaded couplings are commonly used in industrial and municipal firefighting operations.
