Steel wire and iron wire have many similarities, but carefully distinguish, will find that they are not only different in the material, but also in the product characteristics of the great difference. So when choosing, be sure to make a clear distinction between the two. Steel wire factory introduces steel wire carbon structural steel made above, generally not galvanized, used for machinery, spring. Black, very hard; Wire: made of mild steel (mild steel), galvanized, used for joining and binding. White and soft.
In the calculation process of 12*14 specifications of barbed rope, it can not be calculated according to the above calculation formula, because first of all, two specifications of raw materials are used, the thinner the wire diameter, the higher the processing cost. Generally speaking, a kilogram of 12*14 barbed rope can reach about 7.5 meters, and the ratio of warp wire to barbed rope cannot be calculated according to the traditional ratio of 7 to 3. The specific use of how much wire and silk need to go through a series of professional measurement but also increase the loss of raw materials and other factors to calculate. Thorn rope factory will also according to customer needs to calculate the reasonable amount of customer use.
The service life of the original galvanized iron welding mesh is very limited. Generally, good iron railings can only be used for about 2 years, and then renovated until the service life, which is not only time-consuming but also has safety risks. After the appearance of zinc-steel railings, the service life has been increased to a great extent in the post-processing. Generally, it can be used for at least 20 years. To improve the service life of zinc steel railings, we first have a brief understanding of the product characteristics of railings. Then from the maintenance aspect, it is necessary to maintain. Maintenance method of electric welding mesh:
Dip plastic hook net disposal characteristics and downwind, dip plastic is also a common comparison, surface treatment color comparison is single, generally dark green, however, if you want to change into other colors, dip plastic will be more convenient. Because its inner line or inner tube is generally iron line, so, after a period of time, the inner line or inner tube will slowly corrode outward, compared to the outside of the glue fade, hook net will die.
The barbed rope factory will store the blade barbed rope in a suitable place when it is stored, because it understands the product characteristics.
Different from the general zinc barbed rope, high zinc barbed rope surface zinc content is very high can reach the former 6-8 times, so in the service life also has a great advantage, ordinary products three or five years began to corrosion and the latter will take longer to change. Stainless steel barbed rope is in the material aspect of protection, so the durability is also better, these two products are long in the service life, but in the price is high.
The bonding and anchoring function between cold wire drawing and cold rolled ribbed steel bar and concrete is outstanding. Therefore, when used in components, the phenomenon of cracking of component anchorage area and damage caused by steel wire slip is fundamentally eliminated, and the load-bearing ability and anti-cracking ability of component end are improved. In reinforced concrete structure, the crack width is smaller than that of circular steel bar or even that of hot rolled thread bar.
Heavy hexagonal mesh is made of steel wire woven into hexagonal mesh by special machinery. This kind of mesh, after cutting and assembling, can be made into fence mesh, mountain hanging mesh, vegetation three-dimensional mesh, assembly, etc.
The vertical distance between the lower edge of the Nestor roller cage and the upper edge of the reinforced concrete protective fence is 0.05m. Longitudinal reinforcement adopts hot-dip galvanized netting, double-twist weaving process, barbed wire 2.2mm, main line 2.5mm, netting joint card adopts galvanized steel plate stamping or Q235 carbon steel plate stamping for galvanized.
