Welding net is generally used in construction, breeding chicken and pigeon rabbit cage, balcony protection, machine cover, flower guardrail and so on. According to the welding aperture, wire diameter is different, the use of welding net products are different, such as: the use of insulation wall welding net on housing construction, agricultural circle corn mesh welding net, the use of breeding chicken, mink and other breeding welding net. So what should be paid attention to when choosing the welding net? Mainly in the following three aspects

Galvanized iron wire can be divided into hot-dip galvanized iron wire and cold galvanized iron wire according to different processing methods. Galvanized iron wire is more prominent in its corrosion resistance. Galvanized iron wire has good toughness and elasticity, the amount of zinc can reach 300 g/square meter, with thick galvanized layer, strong corrosion resistance and other characteristics. Galvanized iron wire products are widely used in construction, handicrafts, wire mesh preparation, the production of galvanized hook mesh, wall mesh, highway guardrail, product packaging and daily civilian and other fields.

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.

5, the concentration of plating aid can not be too high, which is a factor that can not be ignored to reduce zinc consumption. The concentration of plating aid should not be too high. The galvanized line must be added with ammonium chloride and zinc chloride according to the data of laboratory analysis, and the specific gravity of the composite solution should be controlled within the range of 50~80g/L. If ammonium chloride or zinc chloride is arbitrarily added without the results of laboratory analysis, it should be criticized and educated, and economic treatment should be given if necessary.

Galvanized iron wire is a substance we often see in life. It is the zinc gradually plated on the metal surface through the unidirectional current in the electroplating tank. The production speed is slow, the coating is uniform, the thickness is thin, usually only 3-15 microns, the appearance is bright, the corrosion resistance is poor, and the corrosion will rust in a few months. Galvanized wire has the characteristics of thick galvanized layer, strong corrosion resistance, strong galvanized layer, etc., the products are widely used in construction, highway walls, Zahua, weaving nets.

When the pet consignments need to use a special pet cage, usually domestic pet cage are not qualified. Prior to shipment, the pet must be taken to the airport for quarantine inspection. The quarantine certificate should be attached to the waybill. After confirming your flight, arrive at the airport at least 3 hours in advance, anticipate the waiting time and flight time, prepare enough water and food for pets, hot weather, poor ventilation, etc., will cause harm to pets. Those who want to take pets with public transport, must go to the animal quarantine station, with proof of immunity for the county animal quarantine certificate. Clean and disinfect the pet carrier.

Cold wire drawing is a kind of cold processing of metal. The raw material is wire rod, which is produced by peeling, galvanizing and other processes. Galvanized cold drawing is used more in building materials. Its testing standards are also different. The strength of cold drawing is relatively high. Because of the high strength of steel, it plays a very important role in construction. It saves the construction steel in building materials, and also reduces the cost of the project. It also plays a very important role in the structure of concrete.

Different from common zinc barbed rope, high zinc barbed rope surface zinc content is very high can reach 6-8 times of the former, so there is a great advantage in the service life, ordinary products begin to corrosion three to five years while the latter will take longer to change. Stainless steel barbed rope is in material protection so durability is also better, these two products are long service life, but in terms of high price.

The lighting surface of each type of shed is designed to be curved, improving the Angle of the light surface, because the lighting surface is curved, no dust accumulation, good light transmittance, high temperature in the shed, after measurement, the average temperature in the shed is 3℃ higher than the traditional bamboo pole cement column shed, the yield is increased by 15~20%, and the harvest date is advanced. The formula is scientific, the surface does not absorb moisture, do not return halogen through modification technology and scientific production process, solve the greenhouse frame rod is easy to absorb moisture return halogen, poor water resistance and easy to change the shortcomings, so that the greenhouse steel pipe in the high temperature and high humidity environment, few drops, frost phenomenon, and reduce pests and diseases.

There are two varieties of steel grid plate is pressure welded steel grid plate and pressure lock steel grid plate, in many people’s eyes, these two products belong to the same variety, in fact, there are still great differences between them in many places.
