The 75mm self-drilling screws are especially handy in situations where access is limited or when working alone. They speed up construction tasks, from building furniture to installing insulation boards, and can even be used in some forms of metalwork. Their ability to quickly attach materials without damaging the surrounding area makes them invaluable in delicate settings like historical restorations or when working with fragile materials Their ability to quickly attach materials without damaging the surrounding area makes them invaluable in delicate settings like historical restorations or when working with fragile materials
Post time: 20-02-23Cold 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.
- A remarkable characteristic of stainless steel wire rope is its inherent corrosion resistance to concentrated nitric acid and dilute nitric acid, which makes it easy to be distinguished from most other metals or alloys. But high carbon 420 and 440 steel in the nitric acid point test is slightly corroded, non-ferrous metal encountered concentrated nitric acid is immediately corroded, and dilute nitric acid has strong corrosion on carbon steel.
- In addition to these reasons, we should also pay attention to the tooling and process must be stable, and regular testing should be done to ensure the uniformity of galvanized layer.
The main difference is carbon content. Iron has a carbon content of 2.11 percent or more, while steel has a carbon content of 2.11 percent or less. Iron-carbon alloys with carbon content of more than 2.11% are cast iron (pig iron), which are basically not malleable and cannot be drawn into wire. Secondly, the content of impurities is different, and the content of harmful impurities such as sulfur and phosphorus in steel is smaller. Wire general color key, wire color light point, white point.
- Galvanizing refers to the surface treatment technology of plating a layer of zinc on the surface of metal, alloy or other materials to play the role of aesthetics and rust prevention. The main method used now is hot galvanizing. However, hot dip galvanizing industry has been developed with the rapid development of cold strip rolling in the past 30 years. The production process of hot-galvanized sheet mainly includes: raw plate preparation → pre-plating treatment → hot-dip plating → post-plating treatment → finished product inspection and so on.
3.Packaging: moisture-proof paper, woven bag, other packaging can be packed according to customer requirements
Because the large volume of galvanized wire alloy elements in iron ore, can make the copper through the material thickening degree of strengthening, hardness, impact force, strength resistance, closing rate, elongation, so alloy iron in the exercise of good iron, is an important supplementary element. The difference between galvanized wire and general iron wire is very big, general iron wire is cheap, and because iron is not very stable, easy to rust in wet places, so the stability is not very good, life is not very long.
- Quality standard: Zinc content per square meter has reached or exceeded 122g.
Common galvanized iron wire equipment is usually used in barbecue net, barbecue net generally requires to have a long service life, with galvanized iron wire equipment to wire a layer of zinc, barbecue net is not easy to be corroded.
Post time: 14-12-22The material of small hexagonal net is the same as that of other hexagonal net, which is generally made of low carbon steel wire, stainless steel wire and galvanized steel wire as raw materials by the hexagonal net machine.
- Second, word of mouth selection
The reason why there are black spots in wire mesh welding is that the action of wire feeding should be timely filled in the melting time, and the development should be appropriate. There is no argon gas, long burning, large current, long distance, blunt tungsten needle and high molten pool temperature are the fundamental reasons for blackening. Continuous burning, is about active welding machine energy selection, machine welding will appear black spots.

Post time: 19-08-22Galvanized hexagonal mesh is a kind of galvanized metal wire mesh, the mesh shape is hexagonal.
Galvanized wire according to the production technology can be divided into: hot galvanized wire, electroplating wire hot plating: 8# — 36# (3.8mm,0.19mm) electroplating: 8# — 38# (3.8mm-0.15mm)
Post time: 12-06-24- Hexagonal mesh is also known as twisting mesh, thermal insulation net, soft edge net. It has strong structure, flat surface, good corrosion resistance, oxidation resistance and so on.
Some customers just use ordinary fences, but the pictures provided to the barbed rope factory are really used in the barbed rope products of prison, maybe because the customers prefer the style, but such products are really a little overqualified to be installed in ordinary areas. Even if customers prefer such barbed rope products, the high price is also prohibitive. The price and quality of the prison application barbed rope is certainly not the level of the barbed rope we contact in daily life.
First of all: twist and reverse thorn rope durable
One is to do a good job of galvanized wire packaging, to avoid bumping, to ensure the integrity of the zinc layer;
- (4) Stop the use of more than two strands of galvanized iron wire around the operation method.
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.
- Relatively speaking, the wire is relatively soft, suitable for binding. Disadvantages are low hardness, low tension, easy to stretch, not suitable for building materials. In different applicable environment, we should make a reasonable choice. So in the usual use of cold drawing wire and wire, according to their own needs to choose, although the length of the same, but the performance is not the same.
With the improvement of living standards and the reduction of family size, keeping pets is becoming a way of life for many people. According to statistics, the number of pet dogs has reached more than 100 million, and the trend is increasing rapidly every year. Beijing alone had more than 900,000 licensed dogs in 2010, according to a survey, and the number of pet cats is also very large.
- The last is the size of the barbed rope or blade barbed rope. The commonly used size is good, especially for some special-shaped products, which need to be mentioned repeatedly in the production process of the barbed rope factory to avoid unnecessary losses.
- 2, the cage must be strong
In order to orchard special electric galvanized shaft wire in alluvial surface to partially remove the surface film layer, surface impurity and other shortcomings can be found and solved according to the basic technology; Excessive foam is caused by soap and soapable surface active substances such as human fat into the tank. A moderate rate of foam production would be fine. The large amount of fine homogeneous particles in the tank can stabilize the foam layer, but the accumulation of too much solid particles will cause explosion.
Cold galvanized by electrolytic action to metal and other materials surface attached to a layer of metal film, so that the surface of the material uniform texture, anti-corrosion wear, appearance is more beautiful. Hot dip galvanized coating is thicker, generally 30-60 microns, coating corrosion resistance is higher. Suitable for outdoor work of steel parts, such as highway fences, power towers, large size fasteners and other “rough” workpiece long-term rust prevention.
- Most people think that the fine wire of the front and back twist barbed wire is not as thick and durable as common sense, but the front and back twist barbed wire is made of hot-dip galvanized steel wire, which is more than three times greater than the tensile strength of iron wire, and the amount of zinc added is not less than hot-dip wire
