The rest of the common application of galvanized iron wire is screen preparation or welding, construction mesh welding commonly used specifications for 2.0mm or 2.5mm wire diameter, welding size of 1M *2m or according to the height of the floor to customize the size. There is another is the use of electric welding net. The wire diameter of the welding net is relatively fine, and is divided into galvanized wire welding and galvanized welding. That is, galvanized wire is directly welded or black iron wire is welded into a net and then in the two galvanized.

Most of the production enterprises or large public places, they can play a defense hook mesh in the choice of time, often will hook mesh quality in position, so galvanized hook mesh this product few people are interested in, but does this show that galvanized hook mesh is not useful?
- Of course, the quality of any kind of product is also affected by the implementation of the specification by the manufacturer. If the manufacturer of electric welding mesh has no high implementation specification in the production itself, or the procedure specification has declined in the production line, or there is no higher requirement on the production link.

The production process of large rolls of galvanized wire is a level of drawing, through the mold into a slightly smaller diameter than the original. And so on down to the desired length. One pull is not desirable, must be numbered, from coarse to fine is dependent on metal ductility. If it changes too much it just breaks. After drawing to a certain diameter, galvanized, so that the finished product.

The hot dip galvanized hexagonal net is made of low carbon steel wire by mechanized braided welding and then by hot dip zinc treatment. Net color bright white, thick zinc layer, uniform mesh, mesh surface smooth, solder joint tensile resistance, high corrosion resistance.
- There is also a kind of stainless steel welding railing, which is also called: bridge anti-throwing mesh guardrail, in fact, the meaning of the river isolation net is the same. Stainless steel railing is a kind of high performance guardrail which has higher hardness, and corrosion resistance use long life. There are many varieties of it and also different shapes. Its basic function is to connect the guardrail structure. General guardrail thickness should be maintained at 0.7mm and above, the guardrail installation is more complex. If the tube part has some thin, affect the service life of the guardrail.

The large roll of galvanized silk should be coated with oil, the fiber core is dipped in oil, and the grease should be able to protect the fiber core from decay and corrosion, the iron wire moistens the fiber, and lubricates the wire rope from the inside. The surface is coated with oil so that all the wire surface in the rope strand is evenly coated with a layer of anti-rust lubricating grease, which is used for the mine rope with friction lifting and mineral water, to be coated with black grease with increased wear and strong water resistance. Other uses are coated with red oil oil with strong film and good rust resistance, and require it to have a thin oil layer, which is easy to keep clean during the operation.

In order to pack and bind galvanized wire in the surface of the sedimentary layer to local removal of surface film, surface inclusion and other defects can be found and treated by conventional technology; Excess foam is formed when soap and surfactants such as saponified fats are brought into the tank. Moderate rates of foam formation may be harmless. Small, homogeneous particles of large denier present in the bath can stabilize the foam layer. Use activated carbon mat to remove surface active substance. Or through filtration to make the foam is not too stable, which are effective measures; Other measures should also be taken to reduce the amount of surfactant introduced. The electroplating speed can be obviously reduced by the addition of organic matter. Although chemical formulations facilitate high deposition rates, the deposition of organic matter does not meet the requirements of coating thickness, so activated carbon can be used to treat the bath.
-
The temperature of large roll galvanized wire should be controlled at 30 to 50℃ during electroplating. Because the chloride ions in the bath are very corrosive, quartz glass heaters are generally used. Continuous production does not need heating, but needs cooling. Cooling can be in the groove side row thin wall plastic pipe, through the flow of tap water cooling, can also be used as a titanium pipe temperature control device.

Although galvanized iron wire has the protection of galvanized layer, it does not say that it will not rust at all, but delays the time of rust. In general, cold galvanized iron wire can be kept for 1-2 years without rust, hot galvanized iron wire can be used for 8-10 years without rust. If properly maintained, the use time will be longer. So how to prevent galvanized iron wire rust?
- After a long time of use, it will not rust after the corrosion protection layer on the surface of hot dip galvanized barbed rope, because the material inside the stainless steel barbed rope is the same as the material on the surface.
- Hot dip galvanized wire: This product uses excellent carbon structural steel, through drawing, hot dip galvanized processing. Widely used in the manufacture of wire mesh, highway barrier and construction projects. With thick coating, corrosion resistance construction binding with iron wire is 22# (0.71mm), low price, its characteristics of good flexibility, not easy to break, is one of the most ideal binding wire construction industry, the first choice of low zinc cold plating treatment of iron wire. The primary choice of low zinc cold plating treatment of wire.

Hexagonal net value is quite high in landslides, many slope through the baptism of the rain after this, there may occur sediment flow of plague and as a result some losses to the property of the people, have the existence of hexagonal wire netting, can solve this problem, from the fundamental up sediment flow in came it can help guard against protection, achieve low is the loss of many people.
- The management system of the rinsing water after wire pickling should be discharged regularly and regularly, and the rinsing water should be kept clean and low acid value as far as possible. It is more appropriate to control the pH value of 3. The concentration of plating aid should not be too high. The hot plating wire must be added with ammonium chloride and zinc chloride according to the data of laboratory analysis, and the specific gravity of the composite solution is controlled within the range of 50~80g/L. If ammonium chloride or zinc chloride is added without reference to the results of laboratory analysis, it should be criticized and educated, and economic treatment should be given if necessary.
