The nylon head also offers a certain level of vibration resistance, ensuring that once the screw is secured, it remains firmly in place. Moreover, the head's low friction coefficient allows for easier turning and tightening, reducing the effort required during installation. The screw's thread is usually coated with a zinc layer or other anti-corrosion treatment, enhancing its durability and resistance to environmental factors The screw's thread is usually coated with a zinc layer or other anti-corrosion treatment, enhancing its durability and resistance to environmental factors
Hook mesh we usually see everywhere, in fact, hook mesh is a kind of fence, like the highway, stadium fence, road fence, etc., have hook mesh. So what are the effects and advantages of the use of hook net?
- The acid activation solution in the production process can remove the corrosion products and oxide film on the surface of the low carbon steel wire without excessive corrosion to the matrix. Galvanized wire can be zincate galvanized or chloride galvanized process, should use appropriate additives to obtain the low carbon steel wire standard requirements of the coating. When galvanized wire after light plating should be light treatment. Control the temperature of the bath of galvanized wire.
- Welded wire mesh can be made into mesh form, the net surface jinsu or coating process, can be used in welded wire mesh and surface to form a layer of protective film, can effectively make the wire with the outside world with water or corrosive substances isolation, can achieve the effect of growth time, also can make the mesh surface present a different color, make the mesh to achieve the effect of beautiful. After the dip plastic mesh is usually used for outdoor, and column links, can play a protective effect against theft.
The wire mesh is composed of low carbon steel wire or medium carbon steel wire, high carbon steel wire or stainless steel wire. There are two kinds of manufacturing technology of steel wire mesh, one is the weaving method, the other is the welding connection, the formation of grid.
The life of the “wire”, is actually “low carbon steel wire”, carbon content in less than 0.2%. The surface is usually coated with zinc plating because it is easy to rust. Under atmospheric conditions, the galvanized layer will not rust before most of the fall off, relatively soft. The life of the “steel wire”, is carbon content in about 0.6% of the “carbon steel wire”, or carbon content in about 0.8% of the “high carbon steel wire”, they have enough hardness and elasticity after appropriate heat treatment, high strength. Uses such as winding ordinary spring and so on.
Post time: 19-12-22Decorative hook mesh selection of stainless steel, aluminum alloy, brass, copper and other alloy materials, through the special process of preparation of hook mesh. It is a silk screen made of decoration. Today we introduce the aperture and wire diameter of the decorative hook mesh.
- The most obvious gap in a short time is the cross section of this piece, hot dip galvanized barbed wire because it is the surface anti-corrosion treatment, so in the cross section of this piece will appear rust, and stainless steel barbed wire because the internal raw materials and surface raw materials are consistent, so there is no such situation.
Cold wire drawing is a kind of cold processing of metal, that is, we often say reinforcement. Cold drawing process is not messy, cold drawing price based on the quality of cold drawing dividends of different levels, cold drawing production is also a variety of different procedures. The main factor affecting the strength of cold drawing wire is raw materials, which are closely related to the raw materials, strength and diameter of raw materials, and the better the quality of cold drawing wire, the more messy the production process.
Post time: 22-08-22- The above are the three major advantages of the positive and negative twisting barbed wire, mainly including durability, high cost performance, and beautiful appearance.
Post time: 12-04-23This process has no mold, low processing cost, easy forming, can process a variety of shapes and other characteristics are widely used. But the products of the guardrail are powder impregnated plastic. According to whether it needs heating, it is divided into hot dipping and cold dipping. According to the raw materials of dipping, it can be divided into liquid dipping and powder dipping. Hot-dip galvanizing, as a metal anticorrosion method, is usually to put the steel structure to be derusted into the zinc liquid at about 500℃, so that the zinc layer is attached to the surface of the steel structure.

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: 07-03-23The material of steel structure will affect the organization and thickness of hot dip galvanized film. For example, high tension steel containing silicon, carbon content is high, easy to react with molten zinc quickly, the result of excessive growth of alloying, will cause a grayish black appearance, but does not affect its corrosion resistance. Or heat treated steel, if its tensile strength exceeds 90kg/mm2, after hot dip operation, easy to reduce its strength, etc.

On the contrary, the denser the ion deposition, the better the quality of zinc layer. Under the condition that the surface zinc layer is dense and bright, the quality of zinc layer per unit area should reach 80g/m2, and the process parameters should be optimized as follows: current density is 16-20A /dm2, mass concentration of zinc sulfate solution is 500g/L, and pH value is 2.5-3.0.
The welding between low carbon steel, low alloy steel, medium carbon steel, alloy steel and the same kind of metal materials or dissimilar metal materials can be realized. The weld has good comprehensive mechanical properties, tensile strength can reach more than 400MPa.
