The guide frame of spray hook net wholesale is composed of guide beam and park core pile, their interval distance is about 3 meters, the spacing of guide beam should be about 1 cm higher than the wall. When installing the guide beam, its position should be far away from the net, and the surround-pile should not be expanded, which will make the surround-pile sink or change its shape.

Stainless steel wire is characterized by good corrosion, in chemical plants or pharmaceutical industry can often be used to stainless steel wire, suitable for acid, alkali environment. Aluminum alloy wire is characterized by high temperature, can adhere to the high temperature of more than 100 degrees Celsius does not fade, and has good corrosion, patience is also very good. It can be used for device manufacturing in construction industry.

With the improvement of people’s living standards, now many families are raising some small pets, these small pets need a stable nest, pet cage has become a more important choice of people, each pet habits and living habits will choose to adapt to the cage. Pet cage has many types, and selective is bigger, pet cages are generally made of wire, with better coarse, then at the bottom with a wheel base, such a simple pet basket was made, in the wheel at the bottom of the mount is for the convenience of the mobile, a pet cages should also adapt to the location of the production in addition to a door, It is convenient for feeding pets.

The optional height of this type of wire mesh is 1 meter, 1.2 meters, 1.5 meters, 1.8 meters, 2 meters. The latter three are the most commonly used, too low to achieve the fence protection effect. The mesh size is divided into 3 cm and 6 cm, and the vast majority of 6 cm is used.

Bridge protection system generally do not need to install special drainage system, the use of hexagonal mesh gabion cage, the filling is selected stones, the stones are not easy to wear, and between the stones and stones will retain some space, so it is very good to meet the drainage requirements.

“Wet” hot dip galvanizing is also called “molten solvent method” hot dip galvanizing. Iron and steel workpiece through degreasing, pickling and cleaning, it is necessary to set in a special box above the surface of the molten zinc in the “molten solvent” (also called cosolvent), and then into the zinc liquid to galvanized. The molten solvent is usually a mixture of ammonium chloride and zinc chloride, but also other chlorine salts.

Galvanized wire hook mesh is widely used in warehouses, east and west refrigeration, protective reinforcement, parks, zoo fences, Marine fishing fences and construction site fences, mechanical equipment protection. There are two kinds of use, that is, slope protection hook net (slope protection net), coal mine hook net (mine hook net, coal mine support net, roadway support net).

This oxide film has greater elasticity and lubricity, does not affect the accuracy of parts. Therefore, the parts of precision instruments and optical instruments, spring steel, thin steel sheet, fine steel wire and so on are commonly bluing treatment. The commonly used galvanizing treatment of large roll galvanized wire is equivalent to forming a protective layer on the surface of the iron wire. The commonly used methods are hot dip galvanizing, hot spray plating, vacuum plating and so on. Different methods have corresponding characteristics.

The iron is clean and clean, and then solvent treatment, after drying immersed in zinc liquid, iron and molten zinc reaction to produce an alloyed zinc layer, the process is: degreasing – washing – pickling – assisted plating – drying – hot dip galvanizing – separation – cooling passivation. The thickness of the alloy layer of hot plating wire mainly depends on the chemical composition of the steel silicon content, the size of the steel cross-sectional area, the roughness of the steel surface, the temperature of the zinc pot, the time of dipping zinc, cooling speed, cold rolling deformation, etc.

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 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.

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.

For example, Przewalskopeles is a first-class protected animal in China. At present, as long as there are several other przewalskopeles populations around Qinghai Lake in China, according to incomplete statistics, there are only about 1,000 of them left. Stainless steel barbed wire fence net is commonly used in grassland pastoral area of Qinghai Lake, with a height of 1.5 meters.

Carbon spring steel wire current national and occupational recommendation specifications are divided into two types: one is cold deformation steel wire, also known as cold tension spring steel wire. Cold drawn carbon spring steel wire is first quenched by lead to obtain soxhlet arrangement, and then the surface phosphating, with a large surface reduction rate drawn to the finished scale, the steel wire arrangement is fibrous, has high tensile strength and elastic limit, good winding and change function.
