When buying large galvanized wire, first look at the hardness of galvanized wire, only after the hardness reaches the standard can be used. The hardness standard of large coil galvanized wire is a very important performance index and an economical test method. However, for the hardness of metal materials, there is not a unified and clear definition including all test methods at home and abroad.
1. The content of alloying elements.
Stainless steel barbed wire is mainly used in the place near the sea more, wet salty air for metal corrosion is particularly serious, and the selection of stainless steel barbed wire is in order to prevent corrosion.
Hook net: hook net also known as diamond net, rhombus net, slope protection net. It is widely used in warehouse, east and west cold storage, protection reinforcement, park, zoo fence, Marine fishing gate and construction site fence, mechanical equipment protection, highway guardrail, sports place purse Seine, road green belt protection net.
Product features: strong structure, flat surface, with good corrosion resistance, oxidation resistance.

Galvanized wire is coated with a layer of stable zinc on the outside of the wire, and the zinc layer is used to protect the wire and make the service life of the wire longer. In the production of galvanized wire, the wire should be pickled. Pickling is to use some acid mist or acid liquid to wash away some oxides on the surface of iron, that is, rust, and some other corrosion, to achieve the purpose of cleaning iron, so that zinc will fall off when galvanized.
⑹ can not open the groove 1 ~ 6mm thick metal sheet single-side welding double-sided forming.
2. Quantity and packing
The use of packaging galvanized wire with the development of industry and agriculture is also expanded accordingly. Therefore, galvanized silk commodities have been widely used in industry (such as chemical equipment, petroleum processing, Marine exploration, metal structure, electric power transportation, shipbuilding, etc.), agriculture (such as irrigation, heating houses), construction (such as water and gas transportation, wire casing, scaffolding, houses, etc.), Bridges, transportation, etc., in recent years. Because galvanized silk products have beautiful surface, good corrosion resistance and other characteristics, its use is more and more extensive.
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.
The acceptance of cold-drawn low carbon steel wire shall be conducted according to the same production unit, the same raw material, the same diameter, and shall not exceed 30T for an inspection lot, and check the base material into the factory or out of the inspection statement. The inspection items for each inspection lot are appearance quality, diameter error, tensile test (including tensile strength and elongation) and repeated bending test.
Weigh each reel of wire of different specifications, not less than the reel weight required in the contract, and record the value. Contact detection. No contacts are generated for each reel of wire. If there are contacts, no more than three contacts are generated for each reel. Each contact should be smooth surface treatment, the wire can not be pulled off from the contact, in line with customer packaging requirements.
Stainless steel material refers to air, steam, water and other weak corrosive medium and acid, alkali, salt and other chemical corrosion medium corrosion of steel, also known as stainless acid steel. In practical application, the steel with weak corrosion resistance is often called stainless steel, and the steel with chemical corrosion resistance is called acid resistant steel. And galvanized wire has good toughness and elasticity, zinc can reach 300 grams/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance. Products are widely used in construction, handicrafts, silk screen preparation, highway guardrail, product packaging and daily civil and other fields.
The surface coating of galvanized wire can be seen whether the quality of galvanized wire is good or not. If the strength of zinc attached to the wire is very poor, then this galvanized wire do not buy, because this galvanized wire must be poor galvanized wire. High quality galvanized wire in general, the zinc layer attached to the surface of the wire is relatively thick, so when we buy galvanized wire, as long as we look at the thickness of the zinc layer, we can generally judge the quality of galvanized wire.
3, pay attention to the cage height
However, because the bath contains highly toxic cyanide, the gas escaping from the electroplating process will do great harm to the health of workers, and its waste water must be strictly treated before discharge. Galvanized iron wire has good anti-corrosion and anti-rust ability, so it can be used in some outdoor guardrails or fences, especially on handicrafts, which are also of great use. Galvanized iron wire is not easy to rust and oxidation on the surface.
Razor wire, also known as razor wire and razor net, is a new type of protective net. Blade barbed wire has beautiful, economic and practical, good anti-resistance effect, convenient construction and other excellent characteristics, at present, blade barbed wire has been widely used in many countries of industrial and mining enterprises, garden apartments, border posts, military fields, prisons, detention houses, government buildings and other countries of the security facilities.
The production process of large coil galvanized wire is relatively simple. The wire after cleaning is put into electroplating solution first. Of course, the plating solution should contain zinc oxide, a direct current of steel, another zinc plate in the plating solution. The zinc is transferred to the surface of the steel as a molecule. If it shows a bright and beautiful color, the wire is coated with zinc.
6. The barbed rope protective net should be laid according to the terrain of the road boundary. The flat section should be set horizontally, and the slope section should be set along the slope or by the step form.

In order to remove defects such as surface film layer and surface inclusion of large roll galvanized wire, it can be treated by conventional technology. The presence of small homogeneous particles of large denier in the tank can stabilize the foam layer, but the accumulation of too many solid particles can cause explosion. Activated carbon mat to remove surface active substances, or through filtration to make the foam less stable, these are effective measures; Other measures should also be taken to minimize the intake of surface active substances. The electroplating speed can be significantly reduced by the introduction of organic matter.

Now the pet cage on the market is still mainly wire cage, so the identification of wire cage mainly has the following parameters:
The service life of the original galvanized iron welding mesh is very limited. Generally, good iron railings can only be used for about 2 years, and then renovated until the service life, which is not only time-consuming but also has safety risks. After the appearance of zinc-steel railings, the service life has been increased to a great extent in the post-processing. Generally, it can be used for at least 20 years. To improve the service life of zinc steel railings, we first have a brief understanding of the product characteristics of railings. Then from the maintenance aspect, it is necessary to maintain. Maintenance method of electric welding mesh:
