- The diameter of the wire is generally 0.3mm – 3mm, after the wire is not very strong, need to annealing, annealing this step is very important, can ensure the production of galvanized welding net, with good elasticity and toughness. After welding, the welding mesh becomes black wire welding mesh and can not be put on the market, because its corrosion resistance is poor and the service life is short, so it needs to be galvanized or dipped plastic treatment.
- Packaging: Welding mesh is generally packed with moisture-proof paper (color is mostly gray, yellow, plus trademarks, certificates, etc.), some like 0.3-0.6mm domestic sales of small wire diameter welding mesh, because the wire is relatively soft, coupled with small rolls, customers often require baling and bagging treatment, to prevent damage caused by shipment, etc. The wire of the electric welding net is straight, and also with wavy bend (also known as Dutch net). According to the shape of the mesh surface can be divided into: electric welding mesh and electric welding mesh roll.
- Barbed rope used to circle cattle and sheep and other livestock also has one of the biggest characteristics is that the price is relatively cheap, for users engaged in breeding industry, investment is not small, the use of barbed rope to fence on the one hand is to reduce the cost, on the other hand is better protection effect.

The methods to control the thickness of galvanizing are as follows: you can slow down the lifting speed of the workpiece, control the time of galvanizing as far as possible, add the appropriate amount of thinning alloy, reduce the thickness, and improve the temperature of hot-dip galvanizing. But consider the zinc pot, iron pot should not exceed 480 degrees, ceramic pot can be 530 degrees, which can reduce the time of zinc immersion.
- Packaging and binding electric galvanized wire is in the state of liquid zinc, after messy physical and chemical effects, not only on the steel plating thicker pure zinc layer, and also generate a zinc – iron alloy layer. This plating method not only has the corrosion resistance characteristics of galvanized wire, but also has a zinc-iron alloy layer. It also has strong corrosion resistance that can not be compared with galvanizing. Therefore, this plating method is especially suitable for all kinds of strong acid, alkali fog and other strong corrosion environment.

Galvanized wire can be used zincate galvanized or chloride galvanized and other processes, appropriate additives should be used to obtain the coating required by the standards of low carbon steel wire. When the galvanized wire out of light plating should be carried out light treatment, the galvanized wire bath to control the temperature. Now the quality level of galvanized wire on the market is not equal, galvanized wire is also called hot dip zinc and hot dip galvanized, is an effective way of metal corrosion prevention, mainly used in various industries of metal structure facilities.

Open pit coal mine due to poor air quality, a variety of harmful heavy metals are also more, so the corrosion strength of barbed rope products is particularly large, when using galvanized barbed rope must choose hot plating or plastic coated galvanized barbed rope, although the price is slightly higher, but in the long term development is more appropriate. Besides, when the barbed rope is installed near the coal mine, the pile foundation should be fixed to prevent the barbed rope from falling down due to soil erosion, thus losing the protective effect.

The life of the “wire”, is actually “low carbon steel wire”, carbon content in less than 0.2%. The surface is usually coated with zinc plating because it is easy to rust. Under atmospheric conditions, the galvanized layer will not rust before most of the fall off, relatively soft. The life of the “steel wire”, is carbon content in about 0.6% of the “carbon steel wire”, or carbon content in about 0.8% of the “high carbon steel wire”, they have enough hardness and elasticity after appropriate heat treatment, high strength. Uses such as winding ordinary spring and so on.

In order to remove the photosynovium and oxide remaining on the surface of galvanized iron wire after drawing or heat treatment, it is necessary to do the surface treatment of galvanized steel wire before plating. The common surface of low carbon steel wire is the light synovium or oxide of animal or vegetable oil; Medium and high carbon steel in addition to contain animal or vegetable oil components.

Take 20cm galvanized wire for acid fog experiment, check the zinc content of galvanized wire through the balance to see whether it meets the zinc layer standard required by customers, ensure that the metal wire achieves the role of rust and corrosion prevention, and meet the service life required by customers. Galvanized iron wires must be packed in good condition, bound neatly and orderly, and bound inward to prevent scratches during transportation. The inspection standard of galvanized iron wire also includes the tensile test, which is decided according to the material of the galvanized wire order ordered by the customer, and it needs to be tested by comparing the raw material list.

2, the production and installation is simple and fast, the use of patented friction connection or special connection accessories for installation, greatly improve the installation efficiency.

Operating procedures: When using cold galvanized wire, all tools and stacked objects obstructing activities should be removed from the work site and equipment. When pickling, put the wire into the cylinder slowly to prevent acid splashing on the body. When adding acid, it is necessary to pour the acid into the water slowly. It is forbidden to pour the water into the acid to prevent the acid from splashing out. Wear protective glasses when working. Do not push or beat cold galvanized wire and other articles when handling them.

There are two varieties of steel grid plate is pressure welded steel grid plate and pressure lock steel grid plate, in many people’s eyes, these two products belong to the same variety, in fact, there are still great differences between them in many places.

- The surface of alluvium before hot dip galvanizing of orchard special electric galvanized shaft wire can partially remove the surface film layer, surface impurity and other shortcomings according to the basic technology to find and solve; Excessive foam is caused by soap and soapable surface active substances such as human fat into the tank. A moderate rate of foam production would be fine. There are many fine homogeneous particles in the tank, can stabilize the foam layer, with activated carbon mat to remove surface active substances. Or make the bubble unstable according to overworry, these are all reasonable countermeasures; Other strategies should also be used to reduce the amount of surface-active substances introduced. The introduction of organic matter can make the electroplating process speed drop sharply. Although the secret recipe of organic chemistry is beneficial to the high accumulation rate, the thickness of the coating can not meet the requirements after the organic matter is brought in, so the activated carbon can be used to solve the tank.

Black iron wire application in the process, the main is through the hot metal billet rolling into six point five mm wire rod, and then put it in the drawing into a line of different diameter, the plant and then gradually narrow drawing plate aperture, cooling and annealing, plating process, such as making a variety of different specifications of the wire, the wire compared with ordinary black iron wire, will be more softer, Softness is also very uniform, color is also consistent, widely used in the construction industry, mining, chemical industry, welding mesh, welding coat hanger, reprocessing industry and so on.
