For example, Przewalskopeles is a first-class protected animal in China. At present, as long as there are several other przewalskopeles populations around Qinghai Lake in China, according to incomplete statistics, there are only about 1,000 of them left. Stainless steel barbed wire fence net is commonly used in grassland pastoral area of Qinghai Lake, with a height of 1.5 meters.

Strictly control the pH value of large roll galvanized wire bath, research shows that the size of the bath pH value directly affects the quality of steel wire coating, improper control of pH value will cause loose coating. When the pH value is greater than 3, the steel wire coating has burr caused by fine dendrites, and the surface is not smooth. The current density is strictly controlled. From the microscopic morphology, the higher the current density, the larger the zinc layer grain deposition, the less dense the corresponding zinc layer.

The galvanized layer forms a particular metallurgical structure that is capable of accepting mechanical damage during transport and use. Every part of the plating can be zinc plated, even in dents, sharp corners and hidden places can be fully maintained. The galvanizing process is more convenient than other coating construction methods, and can avoid the required time after the installation on the site.

Barbed wire was used as a barrier to livestock theft, for one thing, because the surface was covered with sharp spikes that made it very difficult to penetrate through the barbed wire. On the other hand, it is because livestock generally have the habit of running into each other, which makes livestock dare not run into each other with the barbed rope, thus saving the user’s use cost.

Application range of hot dip galvanizing: because of the thicker coating, 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 agricultural field such as irrigation, greenhouse and construction such as water and gas transmission, wire casing, scaffolding, Bridges, road guardrail and other aspects, has been widely used.
- 3. Scope of application. Electrogalvanizing involves more and more extensive fields, fastener products have been widely used in machinery manufacturing, electronics, precision instruments, chemical industry, transportation, aerospace and so on in the national economy is of great significance.
- The third is the service life.

Cold galvanizing (galvanizing) is in the plating tank after the current unidirectional, so that the zinc gradually plated on the metal surface, slow production speed, uniform coating, thin thickness, usually as long as 3-15g, bright appearance, poor corrosion resistance, usually a few months will rust. Compared with hot dip galvanizing, the production cost of electric galvanizing is lower.
-
Fence use: The use of the fence is generally one meter two to two meters a height of the impregnated welding mesh, mesh mostly 6cm, wire diameter from 2mm to 3mm.

- The application range of small hexagonal mesh is also relatively wide, can be used for building wall fixed insulation layer, pipeline, boiler fixed heat preservation, decoration and other fields.

Carbon spring steel wire should have high tensile strength, elastic limit, endurance and fatigue strength, and impact and vibration resistance. To ensure the strength and endurance index, especially to avoid changing the occurrence of cracks, is the key to produce spring steel wire. The inner quality and surface quality of the wire rod directly affect the function of the wire.

Stainless steel is short for rust acid steel, air, steam, water and other weak corrosion medium or stainless steel is called stainless steel; And the chemical corrosion resistance medium (acid, alkali, salt and other chemical etching) corrosion of steel called acid steel.

Steel mesh manual binding line of the joint simple sliding, steel and concrete strength is weak, simple crack. The welded joint can accept not only pressure but also shear force. Longitudinal and transverse steel bars form a network structure, which plays a bonding anchorage effect. The number of solder joints per unit area is added when the diameter of the wire mesh is small and closely spaced. More conducive to strengthening the crack resistance of concrete, can reduce more than 75 percent of the attack of steel mesh cracks is a new, energy-efficient steel mesh structure, used in beams and columns, floors, roofs, walls, concrete pavement, bridge deck paving and other industrial and civil buildings.
-
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.
