Tek screws are designed to withstand considerable stress and strain. Made from high-quality steel, many 25mm tek screws feature coatings that enhance their resistance to rust, corrosion, and wear. This durability makes them suitable for both indoor and outdoor applications.
Post time: 05-05-23Because 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.
- Generally speaking steel does not rust easily with chromium content of 10.5%. The higher the content of chromium and nickel, the better the corrosion resistance, such as 304 material nickel content in 8-10%, chromium content of 18-20%, such stainless steel in general is not rust.

Compared with the traditional braided and twisted barbed rope, the price of raw materials is relatively high because of the relatively complex technology.
Post time: 30-05-22In 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.
The wire used for barbed wire is woven or welded with low carbon steel wire, medium carbon steel wire, high carbon steel wire, stainless steel wire and other materials. The production process includes: general braid, embossed braid and spot welding. If the material is steel wire, after equipment processing into a network, it is called wire mesh.
Hook mesh wire diameter has thickness, fine wire diameter is generally 0.5mm-2.0mm, thick wire diameter can be in 5mm-22mm. Hook mesh is also customized according to different uses, in general, fine silk can be woven into a relatively small hole, thick silk is generally called heavy hook mesh, mainly used in the screening of stones and coal, in short, hook mesh has an important role in many professions.
- The material of wire mesh can choose galvanized wire, stainless steel wire, copper wire, coated wire, lacquer wire, etc., different materials are used in different fields, such as construction, culture, decoration, etc.
- 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.
The production process is to roll the hot metal billet into 5mm thick steel, and then put it into the wire drawing device, draw into different diameters of the line and gradually reduce the aperture of the wire drawing disk. Production process through cooling, annealing, coating and other processing technology, and then made into a variety of different specifications of galvanized wire. Galvanized wire production because of simple process, wide application, early development. Galvanized wire or steel wire is a cold working product of steel wire, and the material used is generally low carbon steel or stainless steel.
Galvanized wire to galvanized uniform, a body is now its cross section, the second is the longitudinal uniformity. In the actual operation process, such as the jitter of steel wire, the surface of the pot scum and other reasons will cause galvanized wire surface galvanized layer accumulation, should try to solve the problem.
- For example, in gray iron, its carbon exists in iron ore in graphite condition, the crack is often gray, soft and strong, simple filtering, suitable for casting. In white iron, its carbon and iron together into iron carbide, crack appears white, very strong and brittle quality, for the material of malleable steel. The alloy grade consists of various alloying elements with different compositions and structures.
- Mainly suitable for flat welding.
- After a long time of use, it will not rust after the corrosion layer on the surface of the hot-dip galvanized barbed wire has problems, because the material inside the stainless steel barbed wire is the same as the material on the surface.
1. PVC plastic coated barbed rope adopts flexible structure
4. Keep the rinse water clean after pickling the steel wire
- Power plant insulation pipe insulation layer to be wrapped with metal mesh, commonly used is galvanized hexagonal mesh, the general specification of aperture 1.5-2.5cm, wire diameter: 0.5-1.0mm.
With the improvement of people’s living standards, kittens, dogs and other small pets also need a stable nest, pet cage has become a more important choice for people to raise pets. Suitable cat cage, dog cage is very necessary for kittens and dogs. There are many kinds of pet cage, cat cage, dog cage selectivity is relatively large, pet cage is generally made of thicker wire, and then get a base with wheels at the bottom, such a simple pet cage is made.
The quality of hot-dip galvanized barbed wire is only good in the surface of the wire attached to the galvanized layer, and with the chemical reaction, the surface of the zinc layer will gradually lose effect because of the oxidation reaction, this situation is more prominent in the humid area of the environment. And because after all, it is rusty iron wire, so the quality of hot-dip galvanized barbed rope is certainly not up to the level of stainless steel barbed rope.
Large rolls of galvanized wire in oxygen violently extinguished, spark, and sodium block, magnesium strip in oxygen extinguished, no spark phenomenon. This phenomenon is determined by the composition of galvanized wire. The galvanized wire used in the experiment is pig iron or steel wire, pig iron and steel are iron and carbon alloy, containing iron and carbon two elements of complex material. Carbon in galvanized wire will produce carbon dioxide when extinguished, solid into gas, volume will shrink rapidly.
Hot dip galvanized welding mesh is made of iron wire, processed by precision automatic mechanical technology. The mesh surface is smooth, the structure is strong, and the integrity is strong. Even if the local cutting or local pressure is not relaxed, the hot dip zinc is processed. Hot dip galvanized welding mesh surface white color, thick zinc layer, high zinc content at the solder joint, uniform mesh, flat mesh surface, solder joint tensile resistance, high corrosion resistance. It has the advantages that ordinary barbed wire does not have.
