For the specification of galvanized wire, the galvanized wire produced by our factory can range from No.8 to No.22, which refers to the BWG standard, that is, from about 4mm to 0.7mm, which can basically cover the type required by customers. As for the raw material of galvanized wire, normally, we use Q195 mild steel, and some factories will also use SAE1006 or SAE1008. The following is the zinc coating, for galvanized wire, this thing is more important, the general zinc coating is about 50g/m2 to 80g/m2, some customers need high zinc galvanized wire, zinc coating can reach 200g/m2 to 360g/m2. The tensile strength of galvanized wire is usually 350n/m2 to 800n/m2. Then there is the packaging specification of galvanized wire. The specifications of small rolls of galvanized wire are 50kg/ roll, 100kg/ roll and 200kg/ roll. Of course, there are large rolls of galvanized silk, the weight can reach 300kg/ roll or 800kg/ roll.

Post time: 16-11-22 - The installation mode of blade barbed rope consists of welded steel mesh and blade gill mesh. Galvanized bayonet rope, barbed wire, snake belly knife bayonet rope, flat bayonet bayonet, bayonet bayonet fence and other new protective net products. One of them. Spiral blade rope, also known as snake mesh, is divided into single ring blade rope and spiral cross blade rope two kinds. Single edge barbed wire without barbed wire, also known as barbed wire, is a new type of barbed wire, is a new type of protective net.
- Some welding methods of galvanized steel mesh will reduce the quality of low carbon steel welded joints, such as electroslag welding. Because the line energy is high, the coarse grains in the heat affected zone of welding will become very coarse, leading to a severe reduction in impact toughness. After welding, it is necessary to normalize with refined grains to improve impact toughness.

Poor pretreatment before electroplating; Bath temperature is too low; Poor quality additives or excessive additives and organic impurities can cause poor bonding. The quality of the additive also has an effect on coating foaming. Some additives react incompletely during synthesis and continue to polymerize during long-term storage or use. The additive tends to distort the lattice and create stress, causing the coating to blister.

- I’m going to take the middle one. Steel wire galvanized is very important, must master galvanized, galvanized, because there are many methods, but we first must choose hot plate, welding mesh material, and then excitation, and diameter of steel wire is mainly according to the construction requirements, as well as the requirements of the range of application.

And high quality data and production cost and production conditions are bound, so some welding screen manufacturers did not meet the requirements of this aspect, natural in this case there is no way to improve product strength. In addition to data, and produce process, even if again good data, but the factory did not meet the requirements of production process in welding, also can form the product under the high pressure welding, so it is also a kind of strength on the decline, process conditions of different manufacturers also have very big difference, so it formed a shopping mall on the above products are differences of strength.

- Packaging: electric welding net general packaging for moisture-proof paper (color is mostly gray white, yellow, plus trademarks, certificates, etc.), some like 0.3-0.6mm domestic sales of small wire diameter electric welding net, because the wire is relatively soft, coupled with small volume, customers often require packing processing, in order to prevent shipment caused by damage. The wire of electric welding mesh has straight, also has a wavy bend (also known as the Dutch net)

The type of barbed rope is mainly reflected in the specification of the wire diameter, the thicker the diameter of the barbed rope produced is shorter, at the same time, the price is cheaper, mainly because the production efficiency is relatively high, because the price of the barbed rope is calculated according to the weight when it is sold. On the contrary, the finer the diameter of the wire, the longer the price is higher.

The formation process of hot dip galvanized layer is the process of forming iron-zinc alloy between the iron matrix and the outside pure zinc layer. The surface of the workpiece forms the iron-zinc alloy layer during the hot dip plating, so that the iron and pure zinc layer is well combined. The process of large roll galvanized wire can be simply described as: when the iron workpiece is immersed in the molten zinc solution, the first zinc and α-iron (body-centered) solid melt is formed on the interface. This is a crystal formed by the matrix metal iron dissolved with zinc atoms in the solid state. The two metal atoms are fused with each other, and the gravitational attraction between the atoms is relatively small.
- The two spines are 7 to 8 circles in the middle, while the ordinary spines are only 3 and a half circles, showing neat and beautiful. Now domestic customers see the positive and negative twisting rope, the impression is that the silk is too thin, can not play a protective role, in fact, it is not.
- If the requirements are not high, and the ventilation is good, and relatively dry place, it is recommended to use electric galvanized barbed rope, because the price of this product has a certain advantage, for ordinary users, this is a more appropriate product.

Therefore, the rust of galvanized black iron wire has a great relationship with storage. At the same time, after rust, it should also be reasonable for post-treatment to avoid affecting its use effect. Of course, when the black iron wire is galvanized, the thickness of the galvanized layer should be ensured, so that the possibility of rust can be reduced. Speaking of galvanized iron wire, perhaps many people think it is relatively rare, in fact, it is not.
