  • The use of galvanized anticorrosion treatment is better, the metallurgical connection between galvanized layer and steel, combined with the appearance of steel as a whole, making the coating more durable, more reliable. In the suburbs, the galvanized thickness of hot dip galvanized can adhere to more than 50 years without repair, in the suburbs or near the seaside, galvanized layer can adhere to more than 20 years without repair, is the choice of anti-rust and anti-corrosion. Coating has strong toughness, in the process of transportation or use, can resist extrusion, withstand some damage, hot dip galvanized anticorrosion treatment both save time and effort, and faster than other processing, than dipping, spraying to save much time and effort.

  • In the rolling process, if the surface of the steel wire is rough, the relative friction coefficient of the steel wire and roll increases, the friction resistance increases, the steel wire elongation decreases, the width increases. In the production of weighted leather material is easy to wide, is because of its rough surface. On the contrary, the surface of the steel wire is smooth, because the friction resistance between the steel wire and the roll is small, it is easy to extend, and the width is small. Domestic steel wire in order to prevent rust, the surface coated with butter, such as butter removal is not clean, easy to slip when rolled flat, also affect its width.
  • Material: galvanized silk

  • With the development of mining industry, pig iron classification in Our country has been very extensive, to meet the needs of the machinery industry. Generally speaking, iron wire factory produces galvanized iron wire iron can be divided into two categories, is directly from the iron ore through iron tracing exercise out of the metal, the primary components of the ore is iron oxide, silica and other miscellaneous stones. When this ore is specially refined into metal iron, the elements such as carbon, silicon, manganese and so on are mixed in, so that the refined data is called – like general pig iron, also for the initial grade of the material.

  • Stainless steel barbed wire is mainly used in the place near the sea more, wet salty air for metal corrosion is particularly serious, and the selection of stainless steel barbed wire is in order to prevent corrosion.

  • 4. When the dog is tired or nervous, it can enjoy its own private space in the cage and let it have a good rest.
  • In this temperature range, the zinc solution is severely corroded to the workpiece and the zinc pot, and the iron is lost at 560 degrees Celsius to add obviously, and the zinc will be the iron substrate above 660 degrees Celsius, zinc slag will be added quickly, plating cannot be used. Therefore, electroplating is carried out in the range of 430~450 degrees Celsius.

  • 4. When cleaning the cage, remember not to brush violently, but pay attention to the strength. Otherwise easy to damage the surface of the paint layer.
  • Although to be able to reduce the cost of production, but the overall strength of the product will have a great lack, so in this case will also let it have a great strength drop. Of course, in the mall, the higher the intensity of the data in the production of the higher the implementation of norms, naturally there will be certain progress in the price.
