- Galvanized iron wire is divided into hot galvanized wire and cold galvanized wire (electric galvanized wire) is made of low carbon steel, after drawing molding, pickling rust removal, high temperature annealing, hot galvanized, cooling and other processes. Galvanized iron wire has good toughness and elasticity, zinc content can reach 300 grams/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance. The products are widely used in construction, handicrafts, wire mesh, galvanized hook mesh, spackle mesh, highway fence, product packaging and daily civilian and other fields.
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.
There are three methods to detect the thickness of zinc layer of galvanized wire: weighing method, cross section microscopy method and magnetic method, among which the first two experiments will cause certain damage to galvanized wire, including the length of galvanized wire and the reduction of dosage. The general detection of galvanized wire galvanized layer is detected by magnetic method, which is also a more intuitive and convenient method. The standard of galvanized layer thickness is related to the wire diameter of galvanized wire. The larger the wire diameter of galvanized wire, the thicker the galvanized layer is. It is the thickness of galvanized layer and cast iron after centrifugal separation.
- Packing is also very important. The cut wire should be bundled and tightly packed with plastic film, and then placed in a regular box. The whole box should be filled and sealed. It is better not to have half a box.
The steel mesh is also called longitudinal reinforcement and transverse reinforcement. The longitudinal reinforcement and transverse reinforcement are spaced at right angles to each other, and all the crossing points are welded together. It has the characteristics of crack – proof, small error and good quality. Steel mesh is mainly used in coal mine roadway, concrete pavement, bridge deck, airport runway and buildings. So, what are the advantages of mesh?
- The wire mesh is finished by fine welding of active welding equipment. The material can be divided into cold drawing wire, hot dip galvanized, cold galvanized, dip plastic and so on. To be used for bridge reinforcement, deck paving, building reinforcement, etc.
If the surface of galvanized wire is black and the galvanized layer is thin and uneven, the galvanized wire is partly because the inventory storage time is longer, but also because the production technical requirements of galvanized wire do not meet the standard and lead to the quality problems of galvanized wire. According to the use of galvanized wire is different, galvanized wire has soft and hard, then the galvanized wire used for binding requires the flexibility of galvanized wire is better, the flexibility of galvanized wire is good, and it can be easy for workers to operate.
- Two is to pay attention to the storage and use of galvanized wire products, according to the actual environmental standards to choose different specifications of galvanized wire products;
Post time: 27-07-22
Post time: 28-12-22- 1, we should pay attention to the welding mesh moisture-proof: if it is just the general outdoor air humidity, do not bother. If the weather is foggy, use dry cotton cloth to wipe the bead on the welding mesh; If it rains, you should dry the water when the rain stops. Try to maintain and prolong the life of the welding mesh.
1, galvanized wire mesh molding sheet must be packed with flat hard data, to avoid eternal deformation due to poor packaging. It IS VERY IMPORTANT THAT EACH PACKAGE AND ROLL OF RAW SHEET MATERIAL BE MARKED WITH PRODUCT NAME, STANDARD, QUANTITY, TRADEMARK, batch number, MANUFACTURER, DATE of production, STACKING SYMBOL, INSPECTOR CODE AND INSPECTION CERTIFICATE.
Wire mesh first welding after galvanized is through the end of welding and then the company to produce wire mesh wire mesh steel mesh construction mesh, floor heating mesh galvanized or hot dip galvanized. First galvanized after welding is to change wire mesh, after the end of welding can see the solder joint; The two processes are different in price. The cost of plating after welding is low, the appearance is smooth, and the cost of plating after welding is high, and it is not easy to rust.
- In the rolling process, if the surface of the steel wire is rough, the relative friction coefficient of the steel wire and roll increases, the friction resistance increases, the steel wire elongation decreases, the width increases. In the production of weighted leather material is easy to wide, is because of its rough surface. On the contrary, the surface of the steel wire is smooth, because the friction resistance between the steel wire and the roll is small, it is easy to extend, and the width is small. Domestic steel wire in order to prevent rust, the surface coated with butter, such as butter removal is not clean, easy to slip when rolled flat, also affect its width.
2, mesh, mesh also directly affect the price of stone cage net
- 4. When cleaning the cage, remember not to brush violently, but pay attention to the strength. Otherwise easy to damage the surface of the paint layer.
Cold galvanized, generally speaking, do not need heating, galvanized amount is little, this galvanized parts are easy to fall off in wet environment. Hot dip galvanizing, also known as hot dip galvanizing, is to melt the zinc ingot at high temperature, put some auxiliary materials in, and then dip the metal structural parts into the galvanized groove, so that the metal members are attached to a layer of zinc layer. The advantage of hot dip galvanized is that its anticorrosion ability is strong, the adhesion and hardness of galvanized layer is better.

Post time: 30-05-22- 2, galvanized wire mesh molding sheet storage ground should be flat, according to the symbolic requirements of the accumulation of regular, height should not exceed 2M, and away from heat sources, avoid exposure.
Flexibility because the wire is different from other stainless steel raw materials, it is low density so in the flexibility of the appropriate excellent, it can be described according to people’s fantasy into all kinds of different shapes. Some large enterprises will buy hook flower net products, its reasons are no more than two, one is to prevent people outside the enterprise to walk around at will, the second is to advance the whole image of the enterprise. Therefore, under the premise that the protection requirements are not high, galvanized hook net can play a role in its use, the appearance of flexible hook net is settled to the use of address, from a distance and look at it like a work of art quite appreciate the meaning.
- In the corner area, the zinc layer is often thicker than other places, and has good toughness and abrasion resistance. And other coatings in this corner, often Z thin Z is not easy to construction, Z is easy to hurt, so often need to be maintained. Even if there’s a lot of mechanical damage or something. Causing a small layer of zinc to peel off, leaving the iron base exposed, the surrounding zinc layer will act as a sacrificial anode to protect the steel from erosion.
Galvanized hexagonal net is a kind of galvanized metal wire mesh, mesh shape is hexagonal.
The price of galvanized iron wire is relatively low, but the corrosion resistance is excellent, so it is favored by many screen businesses. In the production process of galvanized iron wire, first of all, we should check the equipment to see if there are any problems, and then we should look at the galvanized process, whether there are factors that cause product discoloration. If these problems do not exist, or some of them occur on the same equipment, and some are normal, then we should consider the problem of raw materials at this time.
Galvanized wire in acid, alkali, sodium chloride aqueous solution of poor corrosion resistance, in the atmosphere containing carbon dioxide and hydrogen sulfide, as well as Marine atmosphere is not corrosion resistance. In high temperature and high humidity air and containing organic acid atmosphere is small, galvanized layer is also easy to be corroded. Galvanized wire and general wire is very different, general wire is cheap, and because the iron is not very stable, easy to rust in the wet place, so the stability is not very good, the life is not very long.
- How much does a spike rope weigh in a meter? In fact, after figuring out how many meters a kilogram of barbed rope, this problem will be solved, and it is OK to divide a kilogram directly by the number of meters.
- Zinc coating on steel and ferrous metal plays an anodic role, it is commonly used for those parts subjected to atmospheric or water action, but zinc coating only when the water temperature below 60℃, the anode properties. When the temperature is higher, the potential changes and the zinc to iron becomes the cathode. Therefore, for parts subjected to hot water (such as steam boilers), the zinc skeleton must be approximately 70 microns thick and void free. For parts subjected to low or normal temperature or atmospheric action, zinc coating without pinholes is not necessary.
Post time: 22-03-23Fence use: The use of the fence is generally one meter two to two meters a height of the impregnated welding mesh, mesh mostly 6cm, wire diameter from 2mm to 3mm.
Razor wire, also known as razor wire and razor net, is a new type of protective net. Blade barbed wire has beautiful, economic and practical, good anti-resistance effect, convenient construction and other excellent characteristics, at present, blade barbed wire has been widely used in many countries of industrial and mining enterprises, garden apartments, border posts, military fields, prisons, detention houses, government buildings and other countries of the security facilities.
