The development of iron wire industry in our country is still very good, among which there is a kind of iron wire called large roll galvanized wire, which is also widely used with its own good performance. In fact, the zinc layer plays a protective effect on the iron wire inside, which can ensure that the iron wire is not oxidized, and it is convenient and beautiful to use. Galvanized iron wire is formed by pickling, high temperature, hot dip galvanizing and other steps. It has good toughness and elasticity and can be applied to many civil fields.

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.

River isolation network because of different regions are not close to the same, some places called river guardrail network, reservoir isolation network and called river bridge guardrail and so on, but they refer to the same kind of product, we all know that the river isolation network fence itself is a kind of obstacle, to prevent people and cars falling into the river, if installed river isolation network will not appear such a problem, Its setting is conditional, generally in the river fence set guardrail and more people and vehicles installed guardrail maintenance, the relative risk of discrimination. As long as the correct planning, guardrail to play its own function and advantages. Today, I will introduce to you the style of the river isolation network.

Spray powder mainly acrylic powder, polyester powder and so on. Dipping is a kind of plastic coating process, that is, the plastic coating on the matrix, generally metal, such as: daily use of clothes hangers, pliers handles, scissors on the rubber sleeve, various handrails, etc. Plastic immersion is to heat the metal to spray plastic powder evenly on the metal to form a plastic film, or heat immersion liquid into the metal to cool it and then plastic coating on the metal surface.

The application of electric welding mesh is more widely, at present, it has replaced the use of other parts of the screen, the cost of electric welding mesh is low, the production speed is very fast, so it is very popular. The treatment required before galvanized welding mesh is recrystallization annealing, because the welding mesh must maintain an oxide and no other impurities of pure iron active surface, if you can’t keep its surface clean will lead to poor galvanized effect, galvanized layer and iron material is not tightly combined, so this step is necessary.

Welding net is widely used in industry, agriculture, breeding, construction, transportation, mining and other aspects. Such as machine shields, animal pens, flower pens, window bars, access fences, poultry cages, egg baskets and home office food baskets, paper baskets and decorative items.

Custom is made of low carbon steel silk woven, mesh structure he has the characteristics of corrosion resistance, high strength and ductility. Steel wire diameter up to 2.0mm-4.0mm, steel wire appearance is usually selected hot dip galvanized maintenance, galvanized maintenance layer thickness can be made according to customer needs, galvanized maximum can reach 300g/㎡.

There is also in the use of places, blade thorn rope is generally installed and used for the border, walls, prisons and so on, and galvanized thorn rope is in the orchard, fence livestock and so on a large area of installation, although the use of large, but not as high as the use of blade thorn rope and grade, so this is the main reason for the high price. Finally, for the blade barbed wire, the general installation site has high requirements for the protection level, so the quality of the product is also relatively high. But the ordinary galvanized barbed wire has relatively low requirements for the quality in the processing process due to the casual requirements at the installation site.

The spray blade has strong adhesion and mechanical strength, and is widely used in the isolation and protection of the boundary of grassland and railway, as well as the protection of garden apartments, units and prisons. The following Haorong for you to introduce the characteristics of spray blade rope.
