  • People who want to keep birds for the long term need to know how to choose the right cage and how to raise them scientifically. It’s all about the birds’ daily life and health. Only by knowing more about the various aspects of raising birds can they be raised healthy and lively, singing freely and suitable for viewing.

  • The application of electric welding network is more and more widely, and the technology is gradually mature, electroplating rust prevention, plastic processing, used for breeding, grille, coupled with the framework made of guardrail network.

  • After the optimization of the process, mass production of 0.80mm electro galvanized steel wire electro galvanized zinc layer quality is controlled within 80 ~ 90g/m2, zinc layer quality dispersion is very small; The results show that the average weight of zinc layer is 14.5g/m2, the loss of zinc layer is less than 5%, and the tensile strength of steel wire is 2300 ~ 2500MPa. It not only effectively controls the quality of zinc layer of raw steel wire, but also reduces unnecessary waste and production cost.

  • A. When the thickness of the plating is 3-4 mm, the zinc adhesion should be less than 460g/m, that is, the average thickness of the zinc layer is not less than 65 microns.

  • Galvanized wire is divided into hot dip galvanized iron wire and galvanized iron wire according to the production process. It has the characteristics of high tensile strength, good softness, zinc layer uniformity, corrosion resistance, beautiful color, good smoothness, strong adhesion and corrosion resistance. Hot dip galvanizing has better protective properties than electric galvanizing, so it is an important protective coating for steel parts used in harsh working conditions.

  • In use, it can be well used to control its soft and hard degree in the annealing process, mainly used in the construction industry as a binding wire and binding line. Of course, its use is not limited to arts and crafts, but also widely used in the construction industry. Earlier woven lanterns were made of iron wire with appropriate candles placed inside. People hung them in front of their doors and looked very beautiful at night.

  • The duration of the protective effect of galvanized layer on large roll galvanized wire is closely related to the coating thickness. Generally speaking, in the dry main gas and indoor use, the thickness of galvanized layer only 6-12μm, and in the environment is more severe conditions, galvanized layer thickness needs 20μm “to be up to 50μm”. Therefore, the influence of environment should be considered when choosing the thickness of galvanized layer.

  • Common weight length conversion of barbed rope:
  • good

  • The difference is that hot dip galvanizing is dipped in zinc solution melted by heating, which has fast production speed and thick but uneven coating. 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. Cold galvanized is in the plating tank through the current unidirectional zinc gradually plated on the metal surface, the production speed is slow, uniform coating, thin thickness, usually only 3-15 microns, bright appearance, poor corrosion resistance, generally a few months will rust.

  • Decorative hook mesh size width generally does not span 2 meters. Generally, the length does not span 4m. It is difficult for workers to span 2m, and it is not good for galvanizing and plating. It can reach 6 meters in length, but it won’t cross 6 meters. Generally across 4 meters after the price will be significantly higher.

  • Aliases: Gabion mesh, heavy hexagonal mesh, ecological mesh, wire mesh, etc.
  • Stainless steel barbed rope in the way of corrosion is not very, because the surface is not treated but rely on its own raw materials for corrosion resistance, so there will be no chemical reaction.

  • The above is to extend the service life of stainless steel barbed rope method, mainly to spray and galvanized.

  • Barbed rope factory not only provides the sales of blade barbed rope, including the subsequent construction is also contracted, and the construction price is particularly different.

  • As we all know, the use of hexagonal net for protection can protect the natural environment while protecting the bridge, which can not only green the ecological environment, but also prevent soil erosion.

  • Blade thorn rope because the volume is relatively large so thorn rope factory is used to packaging treatment.

  • Pet cages can be used for indoor and outdoor pet houses. The dog cage is equipped with a fixed food basin and a drinking device, and the rubber pad of the pet cage with a bayonet on the four sides can be assembled. Can be splicing according to the size of the cage, shear, disassembly convenient, easy to clean, can solve the puppy in the ordinary cage pinched foot problem, prevent the puppy in the development of adverse reactions. The bulkhead of the pet cage is breathable and comfortable, which can be used as a heat shield for pets in summer. A puppy with small feet, not a foot, not a pinch.

  • Small and medium-sized cat cage, dog cage and fence are mostly pure wire welding, wire diameter is generally between 2-5mm. Of course, the larger the cage, the thicker the wire, because the larger cage has to withstand more force.

  • Galvanized wire for welding is generally required to have a certain hardness, after acceptance of galvanized wire, feel is the first thing to do, in addition to the machine test, because the average user does not have testing equipment, on the machine trial is also a very inconvenient way to test. The diameter of electric galvanized wire is measured with a micrometer, and it is kept at about 0.02mm above and below the contract signing standard, with neat appearance, no leakage plating and no messy wire.
