Hexagonal mesh is a metal wire woven Angle mesh (hexagonal) made of wire mesh, the use of metal wire diameter is based on the size of the hexagonal and different. Also known as: twist flower net, stone cage net, gabion net, flood control network.

As we all know, even if it is the same kind of steel wire, because of the steel making process, wire drawing process and equipment are not the same, so the quality of steel wire production is not the same. Due to the different mechanical properties of steel wire itself, flattening process and equipment, the width and elongation of steel wire in the flattening process have different effects. Therefore, in the selection of wire diameter, the following three factors should be considered:
-
Some customers do not understand the scope of application of different styles of barbed rope, there is a great difference.

Galvanized electric welding mesh refers to the mesh made of zinc alloy material, because of its high strength, high hardness, beautiful appearance, bright color and other advantages, become used in residential communities. Traditional electric welding mesh using iron bars, aluminum alloy materials, need to use welding and other technology, and the texture is soft, easy to rust, single color.
- The smaller the mesh of decorative hook mesh, the finer the demand wire, the larger the mesh, the thicker the demand wire. For example, 6.5cm mesh aperture, the required iron diameter is 3.5mm-4mm. Then a fine welding will be broken, and then thick and heavy, workers can not bear.
- 2, mesh, mesh also directly affects the price of the stone cage net
- The most obvious difference in a short time is the cross section of this piece, hot dip galvanized barbed wire because of surface anticorrosion treatment, so there will be rust in the cross section of this piece, and stainless steel barbed wire because the internal raw materials and surface raw materials are consistent, so there is no such situation.
- 4. Packaging: The straightened and cut cold galvanized wire is packaged for transportation and storage.
-
If the coating roughness is not caused by the above reasons, it may be caused by impurities in the plating solution. Can take a small amount of electroplating solution, filtration test, and then take a small amount of electroplating solution, with zinc powder treatment after the test, check the problem is solid particles or copper, lead and other foreign metal impurities caused by. One by one, it’s not hard to find the cause of the problem. Galvanized iron wire coating blister, poor adhesion.

Large roll galvanized wire is processed by low carbon steel wire rod, through drawing molding, pickling rust removal, high temperature annealing, cooling and other processes. Large roll galvanized wire electroplating temperature should be controlled in 30-50℃. Because of the strong corrosivity of chloride ions in bath, quartz glass heater is generally used. Continuous production does not need heating, but need cooling cooling.

The specific design and layout principles are:
- The coating on the surface of the welding core is called the coating. The coating of electrode plays a very important role in the welding process. If the photoelectrode without drug skin is used for welding, in the welding process, oxygen and nitrogen in the air will invade a large number of molten metal, metal iron and beneficial elements such as carbon, silicon, manganese oxidation and nitriding to form various oxides and nitrides, and residual in the weld, resulting in slag inclusion or cracks in the weld. The gas in the weld pool may produce a large number of pores in the weld. These factors can greatly reduce the mechanical properties of the weld and make it brittle.
- After the wire mesh appears black spots, you can choose the appearance of treatment to deal with this problem, such as galvanized, paint, dip plastic to deal with, after the appearance of the welding mesh surface smooth and bright, beautiful and generous.

Galvanized wire A stable layer of zinc is coated on the outside of the wire, which is used to protect the wire and make the wire service life longer. When producing galvanized wire, the wire is pickled. Pickling is to use some acid mist or acid to wash off some oxides on the surface of iron, that is, rust, and some other corrosive substances, to achieve the purpose of cleaning iron, so that zinc will fall off when galvanizing.
- The common barbed rope produced by the manufacturer is the 14*14 type of barbed rope product. Since the warp wire used is the same as the wire diameter of the barbed rope, it is easier to calculate the length and weight. Usually each kilogram of barbed rope can reach about 10 meters of service length. The length of each kilogram of raw material is about 35 meters. Since 35 meters of raw material wire diameter can produce 10 lengths of barbed rope cost.

In order to pack and bundle galvanized wire on the surface of the deposit layer to remove the surface film, surface inclusion and other defects can be found and treated by conventional technology; Excess foam is caused by soaps and saponable fatty surfactants being brought into the tank. Moderate foam formation rates may be harmless. Small homogeneous particles of large denier present in the tank can stabilize the foam layer. To remove surface active substances by matting with activated carbon. Or filtration to make the foam less stable, which are effective measures; Other measures should also be taken to reduce the intake of surfactant. The electroplating speed can be significantly reduced by the introduction of organic matter. Although the chemical formula is conducive to a high deposition rate, the coating thickness cannot meet the requirements after the organic matter is loaded, so activated carbon can be used to treat the tank.

Galvanized hexagonal mesh features: easy to use; Save transportation costs. It can be reduced into small rolls, and involved in moisture-proof paper packaging, occupying little space. Coating thickness uniformity, corrosion resistance is stronger; Simple construction, no special technology; Strong resistance to natural damage and corrosion resistance and the ability to resist adverse climate impact; Can withstand a wide range of deformation and still not collapse. Play the role of fixed heat preservation and insulation.
- Plastic spraying is also known as electrostatic powder spraying. It is the use of electrostatic attack device to make plastic powder charged, adsorbed on the surface of the iron plate, and then through the baking of 180~220℃, so that the powder can be melted and adhered to the metal surface. Plastic spraying products are mostly used in the indoor box, and the paint film appears flat or matte. Spray powder mainly acrylic powder, polyester powder and so on.
