Chinese importers are not just passive recipients of foreign products; they often engage in complex negotiations to secure favorable terms and ensure a steady supply chain. Their influence extends beyond transactional dealings, as they frequently collaborate with producers on research and development initiatives aimed at improving product quality and performance Their influence extends beyond transactional dealings, as they frequently collaborate with producers on research and development initiatives aimed at improving product quality and performance
Cold galvanizing (galvanizing) is in the plating tank after the current unidirectional, so that the zinc gradually plated on the metal surface, slow production speed, uniform coating, thin thickness, usually as long as 3-15g, bright appearance, poor corrosion resistance, usually a few months will rust. Compared with hot dip galvanizing, the production cost of electric galvanizing is lower.
Carbon spring steel wire should have high tensile strength, elastic limit, endurance and fatigue strength, and impact and vibration resistance. To ensure the strength and endurance index, especially to avoid changing the occurrence of cracks, is the key to produce spring steel wire. The inner quality and surface quality of the wire rod directly affect the function of the wire.
The common weight standard of galvanized barbed rope is 25kg per coil, and the length of each coil varies from 220-250 meters according to the specifications of the barbed rope. And of course we all know that the heavier the disc the longer it is. But there is one point that is worth our attention, that is, the hollow inside the general larger disk is relatively small, and the hollow inside the lighter galvanized thorn rope is relatively large. The purpose of this is to reduce the number of bending of the thorn rope and make it easier and more beautiful when installing, on the other hand, it looks larger in appearance.
- If using common galvanized barbed wire due to the influence of climate and environment, will accelerate the corrosion rate of barbed wire lower utilization rate, so use stainless steel barbed wire in coastal areas is the best choice, if it is the environment is dirty it is recommended to use stainless steel barbed wire of nickel content in the highest 316 l, so that you can extend the service life, greatly enhance the protective effect.
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.
Galvanized hexagonal net is a kind of galvanized metal wire mesh, mesh shape is hexagonal.
Due to the implementation of the grassland contract operation obligation system, herdsmen have a high capacity to strengthen and raise their stainless steel barbed rope fence net in grassland pastoral areas, forming the phenomenon of high density and high height of stainless steel barbed rope fence net in grassland pastoral areas, which is destructive and even destructive to the survival of wild animals.

Large roll galvanized wire can be divided into hot-dip galvanized wire and cold galvanized wire, the difference between the two lies in the way of zinc and the amount of zinc. Hot dip galvanizing is to soak steel wire in melted zinc liquid, hot dip galvanizing zinc fast, zinc layer thick rust prevention performance is very good, but the zinc is not uniform, and the surface is dark, the life of hot dip galvanizing can reach 20 years.
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.
1. Electroplating process control
In order to improve the corrosion resistance of steel pipe, the general steel pipe is galvanized. Galvanized steel pipe is divided into hot dip galvanized and electric galvanized. The layer of hot dip galvanized is thick, the cost of electric galvanized is low, and the surface is not very smooth. Used for steel blowing oxygen pipe, generally with small diameter welded steel pipe, specifications from 3/8-2 inches of eight. Made of 08, 10, 15, 20 or 195-Q235 steel strip, in order to prevent corrosion, some should be aluminized.
Post time: 18-08-22But there are some necessary precautions in the production of galvanized wire. Remove all tools and piles on the work site and equipment that hinder activities, and slowly put the wire into the cylinder during pickling to prevent acid splashing on the body. When adding acid, the acid must be slowly poured into the water. Do not pour water into the acid to prevent acid spillage and injury. Workers should wear protective glasses when working. Then in the handling of wire and other items, it is strictly prohibited to push hard.
- 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.
Post time: 28-03-23One: according to the color of the spray blade thorn rope, its price is higher than the ordinary blade thorn rope 2000-2200 yuan, but the price ratio of the spray blade thorn rope is much higher.
2. Eliminate caked zinc residue on zinc liquid surface
- The spring operating at high temperature requires that it can adhere to the elastic limit and good creep resistance at high temperature. In addition, the forming process and heat treatment process of spring steel wire should also be considered. Cold drawn spring steel wire and oil quenched tempered spring steel wire are directly around the supply of steel wire spring, spring forming after the elimination of stress directly used.
- The most obvious gap in a short period of time is the cross section of this piece, hot dip galvanized wire because it is surface anti-corrosion treatment, so in the cross section of this piece will appear rust, and stainless steel wire because the internal raw materials and surface raw materials are consistent, so there is no such situation.
Usually, there are three kinds of metal corrosion: physical corrosion, chemical corrosion, electrochemical corrosion, corrosion in addition to the chemical properties and organizational structure of the metal itself, but also related to the surrounding medium, such as wet environment is easier to rust than dry environment, more impurities than impurities less easy corrosion, high temperature conditions than low temperature conditions easy corrosion. After understanding these, we can effectively prevent the customized corrosion of hexagonal guardrail and extend the service life of the product.
