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.
Post time: 08-03-23Purpose 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.
The main difference is carbon content. Iron has a carbon content of 2.11 percent or more, while steel has a carbon content of 2.11 percent or less. Iron-carbon alloys with carbon content of more than 2.11% are cast iron (pig iron), which are basically not malleable and cannot be drawn into wire. Secondly, the content of impurities is different, and the content of harmful impurities such as sulfur and phosphorus in steel is smaller. Wire general color key, wire color light point, white point.
Strength of galvanized wire: tensile strength is the great tensile stress that the material can withstand before tensile fracture; Yield strength has two indexes: upper yield and lower yield. It is a process in which the stress does not increase but the deformation continues to occur during the tensile process. When the force value drops for the first time, the major stress is the yield strength, and the yield strength must be less than the tensile strength.
Post time: 08-05-23Galvanized iron wire is a substance we often see in life. It is the zinc gradually plated on the metal surface through the unidirectional current in the electroplating tank. The production speed is slow, the coating is uniform, the thickness is thin, usually only 3-15 microns, the appearance is bright, the corrosion resistance is poor, and the corrosion will rust in a few months. Galvanized wire has the characteristics of thick galvanized layer, strong corrosion resistance, strong galvanized layer, etc., the products are widely used in construction, highway walls, Zahua, weaving nets.
Hot dip galvanizing is in the hot melt zinc liquid dip plating, production speed, thick but uneven coating, the market allows the low thickness of 45 microns, up to 300 microns above. It is dark in color, consumes more zinc metal, forms infiltration layer with base metal, and has good corrosion resistance. Hot dip galvanizing can be maintained for decades in outdoor environment.
2. Stainless steel 316 material should be used in coastal areas, which can resist corrosion of sea water.
This oxide film has greater elasticity and lubricity, does not affect the accuracy of parts. Therefore, the parts of precision instruments and optical instruments, spring steel, thin steel sheet, fine steel wire and so on are commonly bluing treatment. The commonly used galvanizing treatment of large roll galvanized wire is equivalent to forming a protective layer on the surface of the iron wire. The commonly used methods are hot dip galvanizing, hot spray plating, vacuum plating and so on. Different methods have corresponding characteristics.
The whole country is cooling down on a massive scale. People suddenly feel that winter is coming. In much of the north, the collection of central heating and heating has also begun. People who do not have central heating or do not want to use traditional heating choose air heating. As heating equipment enters the peak season, building network sales are also gradually increasing.
If it is not packaged, then a car of blade thorn rope can not be loaded with many pieces, and it is also relatively occupied and easy to lose in the transportation process. The number of the packed blade thorn rope is 50 bundles, and the volume is reduced after hydraulic compression so that it is more convenient to load and unload, and the forklift can easily load and unload. Under normal circumstances, when exporting, the blade thorn rope will be packaged and sold, so that the volume occupied in the container is relatively small, which can be easily placed and will not occupy much place.
- From the spraying, spraying blade gill net (PVC blade gill net, coated blade gill net) is also called spraying blade barbed rope, spraying blade barbed wire is produced in the future, to carry out anti-rust treatment attack. Plastic-sprayed surface treatment makes it has quite good anticorrosion ability, beautiful appearance gloss, waterproof effect, convenient construction, economic and practical excellent characteristics. Plastic spraying blade barbed wire is a kind of surface treatment method to spray plastic powder on the product blade barbed wire.
- B. When the thickness of the plating is greater than 4 mm, the zinc adhesion should not be less than 610g/m, that is, the average thickness of the zinc layer should not be less than 86 microns.
Some customers pay more attention to the quality problem, so they pay more attention to the service life. The barbed rope factory will generally recommend the use of high zinc barbed rope or stainless steel barbed rope.

Post time: 20-02-23- Choose a cage that can stand up straight in order to keep your dog comfortable. Lay down with your feet out wide. The dog, can save much, can buy a small cage, can also see it as the same as people, give it a bigger cage, so that it can use half to activity, half to sleep. Use an old blanket for your dog’s crate, or buy a pet mat, as long as it’s comfortable.
- In addition to these reasons, we should pay attention to the tooling and process must be stable, and regular testing should be done to ensure the uniformity of galvanized layer.
Bridge protection system generally do not need to be specially installed special drainage system, the use of hexagonal mesh made of gabion mesh box, the inside of the filler are selected stones, these stones are not easy to wear, and between the stones and stones will retain some gaps, so it is very good to meet the drainage requirements.
- The design is not only for ease of installation, but also for harsh terrain conditions such as cliffs, with little anchorage and little excavation to achieve a quick and easy installation. Based on the characteristics of heavy hexagonal net twisted-pair structure, it can withstand the impact of falling rock even in the case of wire breakage.
- National standards on the use of wire mesh standards have certain requirements, diameter and mesh size matching use, rather than simply diameter size, on the plaster layer to use is mesh should not be greater than 20×20, diameter is not easy to be less than 1mm, light selection diameter is not much significance, choose 40×40×0.9 and choose 10×10×0.6 wire mesh, Which one is better? 10×10×0.6, I’m afraid.
Large roll galvanized wire is made of low carbon steel wire rod processing, is made of low carbon steel, after drawing forming, pickling rust removal, high temperature annealing, hot dip galvanized. Cooling and other surface treatment process processing. Large roll galvanized wire is divided into hot dip galvanized wire and cold galvanized wire (electric galvanized wire). Although galvanized galvanized wire and silver powder paint spray effect appearance is not much different. But the effect is very different, galvanized wire surface is zinc layer, good adhesion, good corrosion resistance.
- The zinc layer on the galvanized wire has good ductility, can be cold blanking, rolling, bending and other molding without damage to the zinc layer. The zinc layer of galvanized wire with thick zinc layer has fine crystallinity, uniform and no void, and good corrosion resistance. The zinc layer obtained by electrogalvanizing is very pure and corrodes slowly in the gas, liquid and fog of acid and alkali, which can effectively protect the steel matrix. Galvanized layer can also be chromate passivation into a variety of colors, beautiful and generous, with good decoration.
- The production and processing process of the blade thorn rope is complicated, which requires the cooperation of all departments, and the production cycle is relatively long. Whether galvanized rope or stainless steel rope, because of the relatively simple structure, the degree of mechanization in the production process is relatively high, so it is also a relatively big difference in price.
- The basic requirements are the flatness of the net surface, hook mesh first after weaving, weaving process, rolling flowers can not turn, to adhere to smooth, can not present wire or turn flowers.
