Cold drawing wire is a metal cold processing, with wire rod as raw material, that is, the mouth of the steel bar. Cold drawing wire is a product produced by a series of processes such as shell stripping, which is a common wire. In the development and production of metal materials, cold drawing wire is a very common material, its performance is good, the range of use is very wide, manufacturers in processing are the use of cold processing to produce.

Hardness is a commonly used property index in mechanical properties of metal materials. The iron wire factory introduces a fast and economical test method for hardness testing. However, for the hardness of metal materials, there is not a unified and clear definition including all test methods at home and abroad. In general, the hardness of a metal is often considered to be the resistance of the material to plastic deformation, scratches, wear, or cutting.

Generally speaking, in dry main gas and indoor use, the thickness of galvanized coating is only 6-12μm, but under poor environmental conditions, the thickness of galvanized coating is 20μm, can reach 50μm. Therefore, environmental factors should be considered when choosing the thickness of galvanized layer. Galvanized layer after passivation treatment, can naturally form a layer of bright, beautiful color passivation film, can obviously improve its protective function, decorative.

Some raw materials in the production of unstable processing, the wire itself will exist burr, surface small pits and other local defects. Galvanized steel in galvanized, generally should pay attention to the galvanized layer protection time of galvanized wire, and the thickness of galvanized layer has a great relationship. Generally speaking, when the main gas is relatively dry and used indoors, the galvanized layer thickness of galvanized wires is only 6-12μm, and under relatively harsh conditions, the galvanized layer thickness of galvanized wires needs 20μm, and can be predicted to reach 50μm.
-
Fence use: The use of the fence is generally one meter two to two meters a height of the impregnated welding mesh, mesh mostly 6cm, wire diameter from 2mm to 3mm.
- 1. Water washing: Clean the galvanized steel wire to remove the residual zinc liquid and impurities on the surface.
- C, coating uniformity: galvanized layer is basically uniform with copper sulfate solution test etched five times without exposing iron.

Cold galvanized, generally speaking, do not need heating, galvanized amount is little, this galvanized parts are easy to fall off in wet environment. Hot dip galvanizing, also known as hot dip galvanizing, is to melt the zinc ingot at high temperature, put some auxiliary materials in, and then dip the metal structural parts into the galvanized groove, so that the metal members are attached to a layer of zinc layer. The advantage of hot dip galvanized is that its anticorrosion ability is strong, the adhesion and hardness of galvanized layer is better.
-
Hot dip galvanizing is dipped in zinc liquid melted by heating, with fast production speed and thick but uneven coating. The market allows a low thickness of 45 microns and a high of more than 300 microns. The color is dark, the consumption of zinc metal is much, the formation of infiltration layer with the matrix metal, the corrosion resistance is good, and the outdoor environment of hot dip galvanized can be maintained for decades. Application range of hot dip galvanizing: because the coating is thicker, hot dip galvanizing has better protective performance than electric galvanizing, so it is an important protective coating for iron and steel parts in harsh working environment. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, power transmission, shipbuilding and other industries, in the field of agriculture such as sprinkler irrigation, greenhouse and construction industry such as water and gas transmission, wire casing, scaffolding, Bridges, highway guardrail and other aspects, has been widely used.

Post time: 10-08-22 - First of all, the protective layer of zinc-iron alloy can prevent the steel wire from being corroded by oxidation. The zinc metal reacts with water and oxygen to form a dense zinc oxide layer, which forms a physical barrier to prevent oxygen and water from entering the inside of the steel wire, reducing the chance of corrosion. Compared with ordinary steel wire, hot-dip galvanized wire is more resistant to corrosion in humid, high humidity or corrosive environments such as acid and alkali, so it is more durable.

The different spacing of the thorn rope is mainly in order to save costs to consider, because if they are too close, then obviously a little waste of resources, but the installation is too sparse will not work. Usually the bottom spacing is about 10cm, and the top is up to 20cm, this is because the higher the place is more difficult to climb over, usually more than one meter without the help of tools it is difficult for ordinary people to climb over, and the bottom because of the relatively tight can prevent personnel from drilling in the past.
- Common weight length conversion of barbed rope:

In reinforced concrete structure, the crack width of cold wire drawing is smaller than that of circular steel bar or even that of hot rolled thread bar. So cold wire drawing is more popular in the construction industry. The material for cold drawing is made of steel bars and can be simply explained how it is made, that is, its production process is simple. It’s based on steel bars, which are constantly stretched evenly, stretching the bars into something very thin, like wire drawing, without plasticity.
- 2.25*2.25mm indicates that the two strands are 2.25mm silk, and the thorn thread is also 2.25mm silk;

1. High tensile strength and durability
- First, cold galvanized wire production process before treatment. Before galvanizing, a series of pre-treatment work on the steel wire is required, mainly including pickling, dissolution and brine or alkali washing.
- Galvanized iron wire is divided into hot galvanized wire and cold galvanized wire (electric galvanized wire) is made of low carbon steel, after drawing molding, pickling rust removal, high temperature annealing, hot galvanized, cooling and other processes. Galvanized iron wire has good toughness and elasticity, zinc content can reach 300 grams/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance. The products are widely used in construction, handicrafts, wire mesh, galvanized hook mesh, spackle mesh, highway fence, product packaging and daily civilian and other fields.
- 6, passivation to remove hydrogen parts should be passivation after the removal of hydrogen, passivation before the application of 1%H2SO4 or 1% hydrochloric acid activation 5~15s. Passivation shall be treated with colored chromate unless otherwise specified in the design drawings.

Most cattle nets are mechanically woven from high ductibility and corrosion resistant low carbon steel wire or PVC coated steel wire. The manufacture of cattle net several common raw materials are generally galvanized wire, hot dip galvanized wire, galfan steel wire plating, ten percent aluminum zinc alloy steel wire and the new selenium chromium wire plating.
- 5, according to the thickness of the wire diameter to adjust zinc dipping time

Post time: 23-08-22 - Pressure welded steel grid plate is the steel grid plate fixed by pressure resistance welding at each intersection of bearing flat steel and transverse bar, which is called pressure welded steel grid plate. Torsion torsion square steel is generally used for cross bar of pressure welded steel grid. Although they do not belong to the same variety, but in the steel lattice plate standards and performance are still the same.
- Although to be able to reduce the cost of production, but the overall strength of the product will have a great lack, so in this case will also let it have a great strength drop. Of course, in the mall, the higher the intensity of the data in the production of the higher the implementation of norms, naturally there will be certain progress in the price.
