Barbed wire is used to make barbed wire, in part, to prevent livestock theft, because the surface is covered with sharp spikes that make it very difficult to penetrate through the barbed wire. On the other hand, it is because livestock generally have the habit of charging, and the barbed rope is used to circle, which makes livestock dare not rush to charge the barbed rope, thus saving the user’s use cost.
- Other discarded guardrails can be used as enclosures for cattle, sheep or other domestic animals. It has a good protective effect. Together these robust products do not have a variety of effects on the overall perimeter. It also shows the value of the rich guardrail network in the community, rural cultivation, or cultivation. Although the appearance of barbed wire fence is not safe after abandonment, the protective function will not be affected, so it will not affect the recovery and use.

A pet carrier can be used as an indoor or outdoor pet house. The dog cage is equipped with a fixed food basin and water fountain, and the foot plate pet cage rubber pad has bayonets on four sides to be splintered. It can be spliced, cut and disassembled according to the size of the cage. It is convenient and easy to clean. It can solve the problem of pinching the feet of the puppies in the ordinary cage and prevent the puppies from causing adverse reactions in the development. The dividers are breathable and comfortable, and can be used as heat shields for pets in summer. A puppy with small feet, no feet, no pinching.
- After a long time of use, it will not rust after the corrosion layer on the surface of the hot-dip galvanized barbed wire has problems, because the material inside the stainless steel barbed wire is the same as the material on the surface.
- Determine the size of the dog cage based on the dog’s actual adult size. In general, the cage should be three times the size of the dog’s body and give him enough room to turn around and so on.
- 2. Take out the items in the cage. First, rinse most of the dirt off the cage with water, and then wipe the dirt around it with a wet towel; And then clean the cage.

When the large roll galvanized wire galvanizing process coating foaming, first check the bath temperature. If the bath temperature is not low, then strengthen the plating before removing oil, prevent the matrix metal in acid corrosion. If you pay attention to these problems, the foaming phenomenon still exists, it should pay attention to the amount and quality of additives, then you can stop adding additives, with high current electrolysis for a period of time, in order to reduce the content of additives, observe whether the foaming phenomenon is improved. If there is still no improvement, it is necessary to check whether the storage period of additives is too long, or whether there are too many impurities in the additives.

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.
-
Hot dip galvanizing has been used for more than 150 years, and its principle has not changed so far. The steel structure should be fully immersed in zinc at one time to achieve uniform galvanized film structure. If it is too long or too wide to be dipped twice, the zinc layer at the joint will appear rough, too thick and so on. In addition, if the single weight of steel structure is too heavy, it will make its operation difficult if it exceeds the load of galvanizing equipment. Therefore, the communication with the hot dip galvanizing factory in advance.

-
2, the production and installation is simple and fast, the use of patented friction connection or special connection accessories for installation, greatly improve the installation efficiency.
- In what aspects is the uniformity of galvanized wire reflected:
- The utility of hexagonal net in the stadium is very superficial, in the stadium built in various cities, are less than the shadow of the hexagonal net. The installation of hexagonal nets around the stadium can not only improve the group image of the stadium, but also facilitate the implementation of a row of activities by urban residents. Because the size of the plane or object surface of the urban area is relatively small, many sports fields are built in the more prosperous and lively sections, with hexagonal nets to protect the barrier, so it will greatly reduce the spherical three-dimensional flying out of the field so affect the traffic order of the bad things.
-
Post time: 31-03-23 - The use of tensioner tension after the thorn rope in the installation, the effect is better, colleagues install the thorn rope net is more straight, but also for the use of the thorn rope is more economical, if not tensioner tension of the thorn rope is not beautiful.

Large roll galvanized wire is like the literal meaning, is wrapped in a layer of zinc on the surface of low carbon steel wire material, beautify the appearance at the same time, but also improve the corrosion resistance of galvanized wire. Zinc dissolves easily in acids and alkalis, so it is called a dissoluble metal. Zinc changes little in dry air. In moist air, a dense basic zinc carbonate film forms on the surface of zinc.
- 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.
