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.
Annealed wire is a soft iron wire made of low carbon steel cold drawing, heating, constant temperature, heat preservation and other processes. The composition of iron wire varies according to its use. It contains iron, cobalt, nickel, copper, carbon, zinc, and other elements. The hot metal billet rolled into 6.5mm thick steel bar is the wire rod, and then put it into the wire drawing device into a different diameter of the line, and gradually reduce the aperture of the wire tray, cooling, annealing, plating and other processing technology made of various specifications of iron wire.
In the thorn rope manufacturer, there are also great differences between hot galvanized thorn rope and cold galvanized thorn rope.
Post time: 28-07-22Hot-dip galvanized wire has longer service life and better corrosion resistance than ordinary steel wire. Hot dip galvanizing is a method of chemical combination of zinc metal and steel wire surface, through the formation of a strong and self-healing zinc-iron alloy protective layer on the steel wire surface, so as to prevent direct contact between the steel wire and the external environment, reduce the possibility of oxidation corrosion, and extend the service life of the steel wire.
Post time: 23-04-23Three methods of twisting the thorn rope: forward twisting, reverse twisting, reverse twisting.
Coping methods we also have: 1, gouging, the straight wire rolled into a wavy shape, but still not enough to raise chickens with mesh can only be large enough to extend the beak can not feed! 2, is the electric welding net, with the current to wire spot welding together, mesh is not limited.
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:
The shape of the cage has round, square, octagonal, hexagonal and other shapes. Because the circular space uses a large area, it is more suitable for the activities of birds, and it is not easy to get hurt, so it is popular with everyone. A cage is dear to a man who loves birds, for it is inhabited by his master’s birds. If well maintained, it can be maintained for many years. Let’s look at how to maintain the cage.
In the purchase of barbed rope should be customer demand, so the amount of galvanized is different, then the two kinds of barbed rope and what is the difference, some customers need high zinc blade barbed rope, but high zinc blade barbed rope price to ordinary galvanized barbed rope price is more than 1000 yuan per ton, the two kinds of barbed rope products, the former is used in many aspects, such as the military, the government’s barbed rope, The latter is more for civilian use.
Galvanized hexagonal net is a kind of galvanized metal wire mesh, mesh shape is hexagonal.
Daily residents still have a demand for galvanized barbed rope, but often the quantity is not particularly large. If the barbed rope factory ships the goods, then the additional freight may be higher than the price of customers to buy the barbed rope in the market. Barbed rope factory for mass purchase of customers to sell their demand is relatively large, but also want to find a manufacturer for procurement is also reasonable. Customer procurement problems can be in the thorn rope factory more perfect introduction at the same time also let the customer more at ease.
The construction of inner wall and outer wall steel wire mesh can effectively solve the wall cracks, falling off, empty drum phenomenon. Hot dip galvanized steel wire mesh material requirements: net surface leveling, width and length to meet the project required standards, welding process, weight, zinc, etc., with more production and operation, detection certificate is complete.
Cooling can be in the groove close row of thin wall plastic pipe, through the flow of tap water for cooling, can also be used as a temperature control device titanium pipe. In the process of electroplating galvanized wire, it is necessary to stir the plating solution to obtain the composite coating with particles dispersing in the matrix metal. Stirring methods include mechanical stirring, air stirring, ultrasonic stirring, bath circulation, etc.
- So why sometimes the size of the bundle is the same, the price will be a little different? This is mainly due to the difference in weight. The lighter the bundle, the lower the price. This is the main factor leading to the relatively large price difference.
That layman how to identify the amount of galvanized, can use the following three methods. Professionals told us that the surface layer of the high-zinc barbed rope would not be particularly smooth due to the zinc behind it, which could be found when comparing the two products. Although the zinc barbed wire zinc layer is thin but relatively smooth.
- Purpose of galvanized hexagonal net: building wall fixed, heat preservation, heat insulation; Power plant tied pipe, boiler warm; Anti-freezing, residential protection, landscaping protection; Raising chickens and ducks, isolating chicken and duck houses, to protect poultry; To protect and support seawalls, hillsides, roads and Bridges and other waterworks.
Did not do the adhesion test of powder spraying or fluorocarbon spray on the packaging galvanized wire, but there are two points for reference: one, in the sealed or air circulation environment, non-metallic volatiles can corrosion zinc coating; Second, zinc above 230 degrees (c) will brittle the base metal. After powder spraying and fluorocarbon spraying, it is necessary to bake at a higher temperature and in a sealed environment, causing rapid corrosion of zinc, resulting in loose corrosion film resulting in decreased adhesion of coating, and even leading to brittle situation of steel wire.
As we all know, even if it is the same kind of steel wire, because of the steel making process, wire drawing process and equipment are not the same, so the quality of steel wire production is not the same. Due to the different mechanical properties of steel wire itself, flattening process and equipment, the width and elongation of steel wire in the flattening process have different effects. Therefore, in the selection of wire diameter, the following three factors should be considered:
- Every part of the plating can be zinc plated, even in dents, sharp corners and hidden places can be fully maintained. The cost of hot dip galvanized rust prevention is lower than that of other paint coatings. The galvanizing process is more convenient than other coating construction methods, and can prevent the time required after the device is painted on the site. In suburban environment, the standard hot-dip galvanized rust prevention thickness can adhere to more than 50 years without repair. In urban or offshore areas, the standard hot-dip galvanized rust protection layer can last 20 years without repair.
Now, hexagonal wire netting is widely used in Bridges, bridge piers and bridge bracket slope protection, cant bridge bracket, there are many people according to the gradient of slope to choose the right hexagonal wire netting, in gentle slope, people usually use bing slope protection system, and in the case of steep slopes, people will use the guest network gravity walls.
- Use: Barbed rope has been widely used in military sites, prisons, government agencies, banks, as well as the walls of residential areas, private homes, villas, doors and Windows, highways, railway guardrail and border lines for protection and security.

Post time: 17-11-22The formation process of hot dip galvanized layer is between the iron matrix and the outside of the pure zinc layer, the formation of iron-zinc alloy process, the workpiece surface in hot dip plating when the formation of iron-zinc alloy layer, so that the iron and pure zinc layer is well combined. The process of large roll galvanized wire can be simply described as: when the iron workpiece is immersed in the molten zinc liquid, the first zinc and α-iron (body-centered) solid melt is formed on the interface. This is a crystal formed by the matrix metal iron dissolved with zinc atoms in the solid state. The two metal atoms are fused with each other, and the attraction between the atoms is relatively small.
