① The diameter of galvanized iron wire for drawing shall not be less than 4mm, and the diameter of galvanized iron wire for binding shall not be less than 2.6mm.
The welding core is the metal core of the electrode. In order to ensure the quality of the weld, there are strict regulations on the content of various metal elements in the weld core. In particular, there are strict restrictions on harmful impurities (such as sulfur and phosphorus), and the quality of the weld core metal should be better than that of the base metal. Arc welding cannot be carried out on a smooth rod without a coating. This is because the arc stability is very poor, splashing is very large, and the weld is not well formed. After long-term practice, it is gradually found that the performance of the electrode is greatly improved by coating the welding core with some mineral raw materials (i.e. electrode coating). (1) Ensure stable arc combustion, so that the welding process is normal. (2) Using the gas produced after the drug skin reaction, protect the arc and the molten pool, prevent the harmful gases in the air (such as nitrogen, oxygen, etc.) from invading the molten pool, such as these gases will cause cracks and pores in the welding material, so that the welding can not achieve the ideal effect. (3) After the drug skin is melted, slag is formed, which covers the weld surface to protect the weld metal, make the weld metal slowly cool, help the gas escape, prevent the generation of pores, and improve the structure and performance of the weld. (4) After melting, various metallurgical reactions will be carried out, such as deoxygenation, sulfur removal, phosphorus removal, etc., so as to improve weld quality and reduce alloying element burning loss.

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.
Thorn rope factory can not only have one type of product when processing thorn rope, a variety of models can meet the protection needs of different customers.
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.
Because of the corrosion resistance of zinc layer, can be applied to all kinds of environment, it is also very convenient to use, has been a more popular hardware products. Galvanized iron wire should pay special attention to the acyl wash, to slowly into the container, to prevent acid sputtering on the body, at the same time prohibit the water into, so it is easy to let the acid out, to learn to handle lightly, stacking should also be firm and neat. It can be widely used in construction, handicrafts and other daily civilian applications.
Since nose touching is an important part of a dog’s social behavior, humans can use this to train them. Experts say that if owners touch their dogs’ noses regularly when they are young, they will have softer personalities and be less likely to hurt when they grow up.3, a wide variety of specifications, a variety of shapes you choose, both European and American style and today’s popular fashion, full noble and modern beauty.

1, galvanized silk mesh molding sheet must be packed with flat hard materials, to avoid improper packaging and cause eternal deformation. It is important that each package and roll of raw material be marked with product name, standard, quantity, trademark, lot number, manufacturer, date of production, packing symbol, inspector code and inspection certificate.
For the wide use of screen, the state has regulations. You also specify the diameter size, mesh size, or usage method. For plastering nets, the mesh should be less than 20 and the diameter should be greater than 1 mm. Not only are specifications specified, but safety is preferred if wire mesh is used in exterior plastering nets. If you fall, the consequences are unimaginable. Therefore, the application of norms should be combined with reality.
After proper heat treatment or cold drawing hardening, high carbon steel wire has high strength and hardness, high elastic limit and fatigue limit (especially notched fatigue limit), cutting function is acceptable, but welding function and cold plastic deformation ability is poor.
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. If adult dogs touch noses with puppies out of affection, adult dogs touch noses with dogs that have more meaning in life. For example, dogs can touch their noses to communicate where food is safe and whether people or other animals are in danger.Specifications: Complete (m)
On the highway, barbed rope protection net is generally to prevent people and animals from crossing the highway at will, so as not to interfere with driving and reduce accidents, as well as effectively prevent illegal occupation of road land and other issues of traffic safety facilities. There are many forms of barbed rope protective nets, commonly used metal, woven net, barbed wire and often green gracilaria. Metal braided net is set in crowded areas, barbed wire is used in areas with few people and animals, and the structure of hedges and barbed wire is used in toll stations and service areas. In the past two years, considering the beauty of the problem, in the Pearl River Delta region of some highways with fruit plastic spot welding network (usually said guardrail network), this barbed rope protection network is more good-looking, durable, the overall effect is good, but the construction requirements are higher, more expensive. General sections should not be used, in the city center, scenic spots or strong requirements for beautiful sections can be used.
