Post time: 06-05-23 - 2, galvanized silk mesh forming sheet storage ground should be flat, according to the symbolic needs of regular accumulation, height should not exceed 2M, and away from heat source, avoid exposure.
- Blade thorn rope plays a great role in railway safety protection, railway blade thorn rope and ordinary blade thorn rope are somewhat different, whether the thorn rope is a strict requirement, the general thorn rope products are not up to this requirement, blade thorn rope can provide a good guarantee for railway safety.

When the zinc layer is seriously damaged and endangers the iron matrix, the zinc will produce electrochemical protection on the matrix, the standard potential of zinc is -0.76V and the standard potential of iron is -0.44V. When zinc and iron form microbatteries, the zinc will be dissolved as the anode, and the iron will be protected as the cathode. Obviously, the atmospheric corrosion resistance of hot dip galvanizing is better than that of electric galvanizing.

Raw material of wire mesh sheet cold drawn low carbon steel wire base material can choose low carbon steel hot rolled disk bar or hot rolled smooth steel bar. The base material number and diameter of cold-drawn low carbon steel wire can be confirmed according to the rules in the table below. During the cold drawing process, the surface shrinkage rate of each drawing should not be greater than the wire mesh before cold drawing. Annealing shall not be carried out during wire drawing. If butt welding is required, the same production unit and base material of the same number should be selected. The appearance quality of wire mesh should not affect wire drawing. When the welding function is poor or brittle fracture occurs, special inspection should be carried out according to relevant standards.
- The form of installation: in the top with the various cage tied together at least as wrapped stone cage net that combination closely not easy to use bad. If the local bandaging is appropriate, it can increase the stability of the structure. There are a lot of grid edge, if the stone cage net only hook in the cage edge and not prepared in the cage edge, even in loose.
- There are many blade specifications, first of all there are three types: spiral type, straight line, spiral cross type. Different units, the strength of the protection of different rope models. The blade barbed wire is mainly made of low carbon steel wire and aluminum magnesium alloy wire by spraying and welding. The blade material of the blade barbed wire is attached to the core wire made of stainless steel wire with professional mechanical strength, so the blade barbed wire has the advantages of good strength and aging resistance.

Generally speaking, in dry main gas and indoor use, the thickness of galvanized coating is only 6-12μm, but under poor environmental conditions, the thickness of galvanized coating is 20μm, can reach 50μm. Therefore, environmental factors should be considered when choosing the thickness of galvanized layer. Galvanized layer after passivation treatment, can naturally form a layer of bright, beautiful color passivation film, can obviously improve its protective function, decorative.
-
Large roll galvanized wire is divided into hot dip galvanized and cold galvanized two kinds, hot dip galvanized color is dark, consumption of zinc metal, and matrix metal formation of infiltration layer, good corrosion resistance, hot dip galvanized can be maintained for decades in outdoor environment. Cold galvanized production speed is slow, uniform coating, thin thickness, usually only 3-15 microns, bright appearance, poor corrosion resistance, generally a few months will rust.
- (2) Electric galvanized shaft wire direct selling shall not be used as waist hoop down reinforcement, usually not used as all binding.
-
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.

The distance between the adjacent two thorn rope installation do not know whether you have noticed? Careful observation can find that its spacing is not the same, the thorn rope factory for customer consultation when asking the installation height of the reason.
-
Generally, due to wet weather and more precipitation, oxidation and rust of binding iron wire NetEase occurs, so we should better store and use galvanized iron wire to avoid rust as far as possible. About the barbed wire, the surface of the barbed wire attached a layer of galvanized layer, the galvanized layer if too thick will not meet the SGS environmental standards. But if it is too thin, it is easy to oxidize with water molecules and rust.

The height of the shield should not be less than two meters. The length of the shield should be the width of the journey and the extension 10 meters away. The vertical load of the handrail on the bridge is 1.2KM/m, and the horizontal external load is 2.5KM/m, both of which should be calculated separately. Galvanized hook mesh belongs to a hook mesh, it is the selection of galvanized wire, hot-dip galvanized wire as raw materials, woven through the hook mesh truncated.
-
There is a connection between the hook mesh and the aperture, in short, the general hole small hook mesh, the wire is also very small; Aperture is large, hook mesh wire is generally larger. The weaving of the hook mesh also has certain rules, using the first pre-bent into a wavy wire, and then woven into the hook mesh. According to the knitting method, the hook mesh can be divided into: closed weaving, two-way plain weaving, one-way corrugated weaving, two-way plane weaving, two-way corrugated weaving, rectangular hole weaving.
- 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.

1. The diameter of raw materials and the thickness of the diameter have a direct impact;
-
In the process of composite electroplating galvanized wire, the plating solution must be stirred to obtain the composite coating in which the particles dispersed in the matrix metal. Stirring methods include mechanical stirring, air stirring, ultrasonic stirring, bath circulation, etc. 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 on the matrix.
- Barbed wire, on the one hand, is a great protection against livestock theft, because the surface is covered with sharp spikes that make it very difficult to penetrate through the barbed wire. On the other hand, because livestock generally have the habit of bumping, the barbed rope is used to circle, which makes the livestock dare not rush to collide with the barbed rope, so as to save the use cost of users.
- The advantage of the steel mesh sheet is that the steel mesh sheet ensures the quality of the project and is made by the automatic and intelligent production line under the strict quality control of the factory. The mesh size, steel bar specifications and quality of the steel mesh are strictly controlled. Avoid artificial mesh leakage, bonding is not strong, bonding error and Jerry construction. The mesh steel has large rigidity, outstanding elasticity, uniform, accurate spacing and high welding point strength. Thus greatly improve the quality of the project.
- 2. When there are natural barriers such as canals, ponds and lakes on the side of the road, barbed rope protection nets shall not be set up in the section where there is no need to worry about people and livestock entering and illegally occupying the road land.

Hook mesh is woven with silk core hook, the mesh is uniform, flat, beautiful and generous net width, thick wire diameter, not easy to corrosion, long life, simple weaving, beautiful and useful. It is widely used to raise chickens, ducks, geese, rabbits and zoo pens. Mechanical equipment protection, highway guardrail, sports venues purse Seine, road beautification with protective net. The screen in the manufacture of a box shaped container, filled with stone cage, can be used to maintain and support the seawall, hillside, road and bridge, reservoirs and other civil engineering.

Hot dip galvanizing is in the hot melt zinc liquid dip plating, production speed, thick but uneven coating, the market allows the low thickness of 45 microns, up to 300 microns above. It is dark in color, consumes more zinc metal, forms infiltration layer with base metal, and has good corrosion resistance. Hot dip galvanizing can be maintained for decades in outdoor environment.
