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.
Material: galvanized silk
Compared with traditional braided and twisted braided rope, the process of blade braided rope is relatively complex, and the price of raw materials is also relatively high.
Hook flower net is made of silk hook, the mesh is uniform, flat net surface, beautiful generous net width, wire diameter is thick, not easy to corrode long life, weaving succinct, beautiful and useful. Widely used for raising chickens, ducks, geese, rabbits and zoo enclosures. Mechanical equipment protection, highway guardrail, sports venues fence, road beautification belt protection network. After the screen is made into a box-like container, it can be used to maintain and support the seawall, hillside, road and bridge, reservoir and other civil engineering.
- The principle of hot dip galvanizing is simply that clean iron parts are immersed in a zinc bath through Flux wetting, so that the steel reacts with molten zinc to produce an alloyed skin film.
Post time: 09-05-23A part of the customers always think that if the price is low to buy the barbed rope products, but often this time to buy the product quality or weight is not up to standard.
- Positive twist: Twist two or more pieces of wire into a double wire rope and then wrap the wire around the double wire. It’s called a positive twist cord which is a common double strand cord.
If the zinc coating is good, but when the light comes out in 3% nitric acid, there is a dark shadow on the coating, and the film is brown when passivation occurs, which may be caused by foreign metal impurities such as copper or lead in the galvanized liquid. When there is a problem in the process of galvanizing, check the temperature and current density first, and then measure and adjust the content of zinc and sodium hydroxide in the bath through the analysis of the bath. Whether DPE levels are low can be determined by Hull cell test.
2. The cleaning agent used for cleaning should have no effect on the binding force of the coating and no corrosion on the matrix.
- The management system of the rinsing water after the steel wire pickling should be regularly and regularly discharged after the rinsing water, and the rinsing water should be kept clean and low acid value as far as possible. The pH control is more appropriate. The concentration of plating aid should not be too high. Hot plating wire must be added ammonium chloride and zinc chloride according to the data of laboratory analysis, and the specific gravity of the composite solution is controlled in the range of 50~80g/L. The addition of ammonium chloride or zinc chloride raw materials without the results of laboratory analysis shall be subject to criticism and education, and economic treatment if necessary.
Open pit coal mine due to poor air quality, a variety of harmful heavy metals are also more, so the corrosion strength of barbed rope products is particularly large, when using galvanized barbed rope must choose hot plating or plastic coated galvanized barbed rope, although the price is slightly higher, but in the long term development is more appropriate. Besides, when the barbed rope is installed near the coal mine, the pile foundation should be fixed to prevent the barbed rope from falling down due to soil erosion, thus losing the protective effect.
Customers do not need to worry about the impact of the production cycle when ordering products from the thorn rope factory, because the overall treatment is now focused on the waste gas, so the production of thorn rope should be said to have the least impact. Customers ordering products in the thorn rope factory can rest assured that the delivery time this piece, can provide customers with goods on time. If the production cycle is not affected, then customers will be more assured of the thorn rope factory.
As we all know, the use of hexagonal net for protection can protect the natural environment while protecting the bridge, which can not only green the ecological environment, but also prevent soil erosion.
Operating procedures: When using cold galvanized wire, all tools and stacked objects obstructing activities should be removed from the work site and equipment. When pickling, put the wire into the cylinder slowly to prevent acid splashing on the body. When adding acid, it is necessary to pour the acid into the water slowly. It is forbidden to pour the water into the acid to prevent the acid from splashing out. Wear protective glasses when working. Do not push or beat cold galvanized wire and other articles when handling them.
Hook fence is made of hook fence for the net surface of the protective net, barrier grid. Material PVC wire, stainless steel wire, good low carbon steel wire, galvanized wire, iron wire hook mesh is made of hook mesh machine for various materials of wire hook knitting, can be divided into two kinds of folding, screwing lock.
- For key and important parts with tensile strength greater than 1034Mpa, the stress should be removed at 200±10℃ for more than 1 hour before plating, and for carburized or surface hardened parts, the stress should be removed at 140±10℃ for more than 5 hours. The cleaning agent used for cleaning shall have no effect on the binding force of the coating and no corrosion on the substrate. Acid activation Acid activation solution should be able to remove corrosion products and oxide film (skin) on the surface of parts without excessive corrosion on the matrix.
- In the cattle net generally also PVC plastic PVC plastic is coated with a layer of dark green or gray brown plastic mold on the original galvanized steel wire, to avoid the corrosion of the wire diameter, is conducive to the improvement of the wire diameter corrosion prevention and rust prevention function. So the better the raw material, the higher the price. Zinc aluminum alloy cattle mesh is the best metal mesh on the market, the price is higher than hot dip galvanized raw materials. The service life is about 80-90 years, excellent anticorrosion function.
Large roll galvanized wire is processed from high quality low carbon steel wire rod. Each wire rod rolled by continuous rolling mill is not less than 200kg, but 15% of the number of plates in each batch is allowed to be composed of two, of which the weight of each rod is not less than 80kg, and 4% of the number of plates in each batch is allowed, and the mass of its single wire rod is less than 200kg, but not less than 40kg. Each rod rolled by semicontinuous mill shall not be less than 60kg, and each batch shall be allowed to have 5% disk nitrogen. The mass of the rod shall not be less than 60kg, but not less than 30kg.

Post time: 07-09-22Cattle net in the outdoor use of a long time will inevitably show rust corrosion, this time the use of cattle net life depends on the maintenance of the product is not in place, we all know that cattle net if long exposure to harsh environment, the service life will be greatly reduced. How long does a normal cattle net last?
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.
- Hot dip galvanized iron wire is made of carbon structural steel, which is processed by drawing and galvanized iron wire. Widely used in the manufacture of wire mesh, highway guardrail and construction projects. It has the characteristics of thick coating, strong corrosion resistance and firm coating. And according to the special needs of users, according to the industry standards to provide various specifications of galvanized wire.
Zinc is a silver-white metal, brittle at room temperature, soluble in acid and alkali, known as amphoteric metal. Pure zinc is more stable in dry air, and small in humid air or water containing carbon dioxide and oxygen. A thin film layer of basic zinc carbonate will be formed on the surface, which can delay the corrosion rate of zinc layer. The corrosion resistance of galvanized layer in aqueous solution of acid, alkali and sodium chloride is relatively strong. It is also not resistant to corrosion in atmospheres containing carbon dioxide and hydrogen sulfide and in Marine atmospheres; In high temperature and high humidity air and containing organic acid atmosphere is small, galvanized layer is also easy to be corroded.
- And the role of wire mesh in the exterior wall plastering if from an Angle to sail a method of anti-falling, the role of anti-cracking is relatively small, because of the problem of orientation; And about the external insulation system is used in the tile veneer, as for the role should also be anti falling followed by anti-cracking, so the grid should be selected 10×10×0.6, these are some experience selection, grid conversion from the national provisions of the wire mesh standard, choose the level of steel content conversion.
- Application scope of hot wire: Because the coating is thicker, hot galvanized has better protective performance than electric galvanized, so it is an important protective coating for steel parts used in harsh working conditions. Hot galvanized products in chemical equipment, petroleum processing, ocean exploration, metal structure, power transmission, shipbuilding and other industries have a wide range of applications, in the agricultural field such as pesticide irrigation, greenhouse and construction such as water and gas transmission, wire casing, scaffolding, bridge, highway guardrail and other aspects, in recent years has been widely used.
Post time: 07-02-23- The common type of barbed rope is double-strand barbed rope, and the models are 2.0*2.0mm, 2.25*2.25mm, 2.7*2.25mm, and all of them are galvanized barbed rope (plastic coated barbed rope is rarely used). The barbed distance (that is, the distance between winding wires) is generally 14 cm. Here’s what these models mean:
Post time: 06-02-231. High tensile strength and durability
In general, the cost of hot dipping zinc is lower than that of other maintenance coatings. The reason is very simple. Other maintenance coatings, such as sand painting, are labor-intensive processes, whereas hot dipping zinc processes are highly mechanized and tightly controlled in-plant construction. Hot dip zinc coating can be visually and briefly tested for non-destructive coating thickness.
- Galvanized wire is coated with a layer of stable zinc on the outside of the wire, and the zinc layer is used to protect the wire and make the service life of the wire longer. In the production of galvanized wire, the wire should be pickled. Pickling is to use some acid mist or acid liquid to wash away some oxides on the surface of iron, that is, rust, and some other corrosion, to achieve the purpose of cleaning iron, so that zinc will fall off when galvanized.
- Hot galvanized products in chemical equipment, petroleum processing, ocean exploration, metal structure, power transmission, shipbuilding and other industries have a wide range of applications, in the agricultural field such as pesticide irrigation, greenhouse and construction such as water and gas transmission, wire casing, scaffolding, bridge, highway guardrail and other aspects, in recent years has been widely used.
- Of course, the quality of any kind of product is also affected by the implementation of the specification of the manufacturer, if it is the welding screen manufacturers in the production of their own is not very high implementation of the specification, or in the production line of the procedure specification has declined, or there is no higher requirements on the production link.
