For the hobbyist, hole cutters simplify tasks like installing door knobs or building a model plane For the hobbyist, hole cutters simplify tasks like installing door knobs or building a model planehole cutter drill bit.Available in 1” deep, 1” x 4” pattern, rectangular mesh FRP gratings are commonly used for walkways and trench applications. When selecting rectangular mesh grating it is important to specify the span (rectangular opening) of the grating perpendicular to the supporting structure.
Heavy hexagonal mesh is made of steel wire woven into hexagonal mesh by special machinery. This kind of mesh, after cutting and assembling, can be made into fence mesh, mountain hanging mesh, vegetation three-dimensional mesh, assembly, etc. Alias: gabion mesh, heavy hexagonal mesh, ecological mesh, wire mesh, etc.
However, because the plating solution contains highly toxic cyanide, the gas escaping in the plating process is harmful to the health of workers, and the waste water must be treated strictly before discharge. Galvanized iron wire has good anti-corrosion and anti-rust ability, so it can be prevented from being used in some outdoor guardrail or fence, especially on handicrafts, handicrafts are also of great use, galvanized iron wire, the surface is not easy to rust and oxidation.
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.
The quality of hot-dip galvanized barbed wire is only in the surface of the wire attached to the galvanized layer, and with the reason of the chemical reaction, the surface of the zinc layer will gradually lose its role because of the oxidation reaction, this situation is more prominent in humid areas. And because after all, the steel wire will rust, so the quality of hot-dip galvanized barbed wire is certainly not up to the level of stainless steel barbed wire.
The thorn rope belongs to the weaving industry, so it is less affected by environmental protection. The thorn rope will not be discarded in the production process, and it belongs to the weaving industry, so the situation is less affected by environmental protection.
According to the galvanized iron wire manufacturer, galvanized iron wire is the selection of excellent low carbon steel, through drawing forming, pickling rust removal, high temperature annealing, hot dip galvanized, cooling and other processes. Galvanized iron wire should pay attention to the following points in the use process:
After annealing, the wire will become soft, flexibility will increase, iron is a relatively active metal, and more active than hydrogen, so it is a good reducing agent. At room temperature, iron in the dry air is not easy to react with oxygen, sulfur, chlorine and other non-metallic elements, its production cost is lower, use and scale is wider, better protection function, so it is an important material for iron and steel parts in a strict working environment.
As we all know, the use of hexagonal net for protection can protect the natural environment while protecting the bridge, which can not only green the ecological environment, but also prevent soil erosion.
Hot dip galvanizing, also known as hot dip galvanizing, is a method of obtaining a metal covering layer by immersing a steel member into a molten zinc solution. With the rapid development of high-voltage power transmission, transportation and communication, the protection requirements for steel parts are becoming higher and higher, and the demand for hot-dip galvanizing is also increasing. Usually the thickness of electrogalvanized layer is 5 ~ 15μm, and the large roll galvanized wire layer is generally more than 35μm, or even up to 200μm. Hot dip galvanized coating ability is good, dense coating, no organic inclusions.
After passivation treatment of galvanized layer, a layer of bright old and beautiful color passivation film can be generated, which can significantly improve its protective performance. There are many kinds of galvanized solution, which can be divided into cyanide plating solution and cyanide plating solution. Cyanide galvanizing solution has good dispersion and covering ability, coating crystallization is smooth and fine, simple operation, wide application range, has been used in production for a long time.
Cold drawing wire is a metal cold processing, with wire rod as raw material, that is, the mouth of the steel bar. Cold drawing wire is a product produced by a series of processes such as shell stripping, which is a common wire. In the development and production of metal materials, cold drawing wire is a very common material, its performance is good, the range of use is very wide, manufacturers in processing are the use of cold processing to produce.
During this process, each time the wire is pulled over, the surface hardens due to the high friction temperature. So basically every time you pull it you have to annealing it in the furnace. On the one hand, it is to reduce the surface hardness. On the other hand, during the process of wire pulling, only the surface is deformed, and the center is unchanged. So there’s a lot of stress inside. Therefore, it is necessary to rely on annealing to eliminate the internal stress, so that the wire becomes soft again to eliminate the stress before being drawn again.
Fence use: generally used as a fence is a plastic-impregnated welded wire mesh with a height of 1.2 meters to 2 meters. Most of the mesh holes are 6cm, and the wire diameter varies from 2mm to 3mm.
There are many ways to choose the blade stabbing rope, and it is necessary to choose reasonably when choosing. Blade barbed rope is very good in the market reputation, and different types of blade barbed rope can play different roles, so how should we choose blade barbed rope? What are the main points?
For mountainous or hilly areas where the ground is more undulating set up stakes. You need to set a stake at the beginning and the end, and then determine the position. In the middle of the ups and downs, to increase the stakes according to the complexity of the ups and downs of the terrain, we need to be able to see 3 stakes at the same time, so that the installation is. It’s a straight line.
