1 1 4 hot dipped galvanized roofing nailsThe electrode is a kind of material that the coating (that is, the coating) is uniformly and centrally applied on the welding core outside the metal welding core. The electrode is composed of two parts: the welding core and the coating. The welding core is the metal core of the electrode. In order to ensure the quality and performance of the weld, there are strict regulations on the content of various metal elements in the welding core. Electrode structure: portable non – electrode, including cylinder, tube, sleeve plug. The electrode is made of metal or metal oxide powder, such as high heat agent and additives. Paper tube is generally used for drug pipe, and metal tube can also be used for different welding parts and use environment. The plug is at the end of the electrode, which is the clamping part that matches the sleeve during welding and prevents the flux from leaking out of the tube.

Because of the high carbon content, simple cracks occur during water quenching, so double liquid quenching (water quenching + oil cooling) is mostly used, and oil quenching is mostly used for small cross section parts. This type of steel is generally used after quenching by medium temperature tempering or normalizing or in the surface quenching state. Mainly used for manufacturing spring and wear-resistant parts.
- Pure zinc is more stable in dry air. In moist air or water containing carbon dioxide and oxygen, the surface will generate a layer of basic zinc carbonate based thin film layer, which can delay the corrosion rate of zinc layer. Comparison of corrosion resistance of zinc coating in aqueous solution of acid, alkali and sodium chloride; It is also resistant to corrosion in atmospheres containing carbon dioxide and hydrogen sulfide and in oceanic atmospheres; In high temperature and high humidity air and contain organic acid atmosphere is small, galvanized layer is also easy to be corroded.
PVC coated barbed rope is widely used for railway highway protection, but also for safety protection of rivers, embankments and seawalls, so as to better protect the safety of people and animals.
When using these two products, it is obvious that there is a gap between them. By pulling or bending the wire, it is often difficult to restore the original, for example, if the same place is repeatedly bent, it will be found that it has broken, and the cold drawing wire will not. Cold drawing wire compared with iron wire, its hardness, tensile resistance, bending ability is greatly enhanced, suitable for building materials.
- Hexagonal cage has a wide range of applications, with the progress of science and technology, has been extended to the major hydraulic, civil engineering. Geotechnical engineering and other projects. In the hydraulic hexagonal cage in the river construction to close the utility, it is considered appropriate to use hexagonal cage to fill stone, fixed river, can be used to avoid river erosion brought water and soil loss. In civil engineering projects, hexagonal cage is considered appropriate and the use of similar particle size volume filling, the connection between the cage is formed into a wall, which is the stone cage mesh retaining wall.

The production and processing process of blade barbed rope is tedious, which requires the cooperation of all departments, and the production cycle is relatively long. The barbed rope, whether galvanized barbed rope or stainless steel barbed rope, due to the relatively simple structure, the degree of mechanization in the production process is relatively high, so this is also a big difference in the price.

Post time: 22-05-23- Barbed rope often appears in another model: 14*14# barbed rope, 12*12# barbed rope, 12*14# barbed rope, among which the diameter of 14# wire is about 2.0 mm, the diameter of 12# wire is about 2.65 mm, there is a non-standard 2.25 mm is also commonly used line. According to this specification, a kilogram of 14*14# barbed rope is 12 meters, a kilogram of 12*14# barbed rope is 8 meters, and a kilogram of 12*12# barbed rope is about 5 meters.
The hot plating wire is made of low carbon steel wire rod, which is processed by drawing forming, pickling and rust removal, high temperature annealing, hot dip galvanizing and cooling. Galvanized iron wire has resistance and elasticity, the amount of zinc can reach 300 g/square meter, with thick galvanized layer, strong corrosion resistance and other characteristics. Widely used in construction, handicrafts, wire mesh, highway guardrail, commodity packaging and ordinary civilian and other fields.
The whole country is cooling down on a massive scale. People suddenly feel that winter is coming. In much of the north, the collection of central heating and heating also began. People who do not have central heating or do not want to use traditional heating choose air heating. As heating equipment enters the peak season, building network sales are also gradually increasing.
Out-of-line annealing means that the recrystallization annealing of hot or cold rolled steel plate is carried out in the bottom type annealing furnace or cover type annealing furnace before entering the hot plating wire line, so that there is no annealing process in the galvanized line. The steel plate must maintain a clean active surface of pure iron, free of oxides and other dirt, before hot dip galvanizing. In this method, the annealed surface oxide sheet is first removed by pickling method, and then coated with a layer of zinc chloride or a mixture of ammonium chloride and zinc chloride solvent for protection, so as to prevent the plate from being oxidized again.
- Galvanized wire is immersed in heated molten zinc, the production speed is fast, the coating is thick but uneven. The thickness of 45 microns allowed by the market, the color is dark, the consumption of zinc metal is more, and the matrix metal is formed into an infiltration layer, and the corrosion resistance is good. The hot dip galvanizing can be maintained for decades in the outdoor environment.
- The steel mesh improves shock resistance and crack resistance. The longitudinal and transverse steel bars of the welded steel mesh constitute a network structure. Therefore, the bond anchorage between the steel mesh and concrete is good, and the load distribution is uniform, which significantly improves the earthquake resistance and crack resistance of the reinforced concrete structure. According to the practice test, the cracks of welding net are reduced by more than 75% than that of manual binding net. Greatly reduce the unnecessary cost of the construction process, shorten the construction cycle, the use of steel wire mesh is simple and convenient, easy to transport.
- 3, twist the weight of hexagonal mesh production plant, the greater the weight, the more sufficient the material.
- The color of powder coating is divided into: razor wire blue, grass green, dark green, yellow. Plastic-sprayed blade gill net is made of hot-dip galvanized steel plate or stainless steel sheet stamped out of sharp knife sheet, high tension galvanized steel wire or stainless steel wire as core wire combination of resistance devices. Because the shape of the barbed rope is not easy to contact, so it can reach an excellent protective barrier effect. The primary raw materials of products are galvanized sheet, stainless steel plate, high quality low carbon steel wire (electric galvanized, hot galvanized, plastic coated, plastic spraying) wire, blue, green, yellow and other colors.
- Uses: used in industry, agriculture, animal husbandry, highway, forest protection

- Galvanized wire hexagonal mesh material: cold galvanized wire, hot galvanized wire, to draw wire
- Because of its light weight, strength is relatively large has gradually begun to replace the original column. At the same time, due to the relatively uniform specifications, the barbed rope installation is also more beautiful. The direct spacing of the barbed rope is relatively fixed, which can effectively prevent crossing. At the same time, the mesh at the bottom is relatively dense, while the mesh at the top is relatively loose, which can save resources.

Post time: 27-12-22The quantity should be the same as the contract, cold drawing, carefully record the quantity of each specification and packing method. If there is a label, check whether the label is correct and take a photo to confirm. Each roll of iron wire is fastened with galvanized packing tape, and then tied with a very strong transparent plastic bag. The coated iron wire is wrapped with white braided cloth, and the galvanized iron wire is wrapped with green braided cloth, so as to ensure that the packaging will not be lax in the transportation process.
There is no need to carry out daily maintenance and maintenance when in use, which can not only save a lot of time, but also reduce the cost, but also has good stability, strong corrosion resistance, greatly extend the service life. According to the different technology is divided into different types, can be selected according to their own needs, has better flexibility and elasticity. The main function of annealing wire is to control its hardness, when the annealing wire is made of steel wire.
