Post time: 18-04-23Different from double strands of barbed wire to install directly on the ground, the blade thorn rope is fixed on some affiliate products just again, as was the case according to the common on the wall, often wall width is far lower than the diameter of the blade thorn rope under the premise of no such device is fixed in place, use special stents to prevent blade thorn rope can better protect us.
Hexagonal mesh is made of galvanized iron wire woven by automatic mesh machine, mesh into regular hexagonal, mesh standard, beautiful, mesh size can be customized according to customer requirements, usually 27mm,20mm, 13mm, wire diameter from 0.40mm to 1.20mm, to meet the requirements of different customers.
- Stainless steel barbed rope is in the material aspect of protection so durability is also better, these two products are known for long service life, but is high in price.
Post time: 12-10-22- 2, pasture installation of thorn rope spacing, if it is cattle or horses due to the larger size, the spacing can be appropriately relaxed. But if it’s a sheep, it’s a smaller animal and you have to make it a little bit narrower.
Stainless steel barbed rope service life is, of course, the longer the better. But do you know how to extend the service life of stainless steel barbed rope?
- After the wire mesh appears black spots, you can choose the appearance of treatment to deal with this problem, such as galvanized, paint, dip plastic to deal with, after the appearance of the welding mesh surface smooth and bright, beautiful and generous.
If it is not packaged, then a car of blade thorn rope can not be loaded with many pieces, and it is also relatively occupied and easy to lose in the transportation process. The number of the packed blade thorn rope is 50 bundles, and the volume is reduced after hydraulic compression so that it is more convenient to load and unload, and the forklift can easily load and unload. Under normal circumstances, when exporting, the blade thorn rope will be packaged and sold, so that the volume occupied in the container is relatively small, which can be easily placed and will not occupy much place.
Galvanized wire can be seen as iron wrapped in carbon. When extinguished, the surface layer is more shallow than carbon can contact with oxygen, produce carbon dioxide gas, and radiate the iron wrapped in it. The more carbon galvanized wire contains, the more obvious the phenomenon of spark. The carbon wrapped in iron acts as if it were an explosive in a charge bag, occasionally blowing the iron apart. Sodium and magnesium contain few flammable impurities, and when extinguished, they just glow.

Black iron wire application in the process, the main is through the hot metal billet rolling into six point five mm wire rod, and then put it in the drawing into a line of different diameter, the plant and then gradually narrow drawing plate aperture, cooling and annealing, plating process, such as making a variety of different specifications of the wire, the wire compared with ordinary black iron wire, will be more softer, The softness is also very uniform, the color is consistent, widely used in the construction industry, mining, chemical industry, welding mesh, welding hanger, reprocessing industry, etc.
- Hexagonal net weaving methods: positive twist, reverse twist, two-way twisting, first editing after plating, first plating after editing, and then divided into hot dip galvanized hexagonal net, electric galvanized hexagonal net, PVC plastic coated hexagonal net, stainless steel hexagonal net, etc.
After proper heat treatment or cold drawing hardening, high carbon steel wire has high strength and hardness, high elastic limit and fatigue limit (especially notched fatigue limit), cutting function is acceptable, but welding function and cold plastic deformation ability is poor.
Wet air in rain and snow climate, steel mesh sheet exposed, easy to rust, to avoid affecting the use of steel mesh, it is necessary to carry out simple rust prevention treatment, of course, slight rust float will not affect the use of steel mesh. Common network site storage, rainy days, heavy snow, rainy days and rainy days, how to better save the steel mesh, this is a lot of friends need to consider.
- In the calculation process of 12*14 specifications of barbed rope, it can not be calculated according to the above calculation formula, because first of all, two specifications of raw materials are used, the thinner the wire diameter, the higher the processing cost. Generally speaking, a kilogram of 12*14 barbed rope can reach about 7.5 meters, and the ratio of warp wire to barbed rope cannot be calculated according to the traditional ratio of 7 to 3. The exact amount of stinging and use the warp need to increase after a series of professional measurement on the loss of raw materials and so on factors to calculate.
Galvanized iron wire is widely used in construction, handicrafts, wire mesh, highway guardrail, product packaging and daily civilian and other fields.
- Because they are afraid of the rain, so there is no need to say more, and the surface of the packaging is more afraid of the sun, so it is not recommended to prevent the outdoor blade thorn rope will cause the woven bag to become ineffective, resulting in the internal blade thorn rope exposed to affect the later use.
Post time: 14-04-23Zinc is a silver-white metal, brittle at room temperature, soluble in acid and alkali, known as amphoteric metal. Pure zinc is more stable in dry air, and small in humid air or water containing carbon dioxide and oxygen. A thin film layer of basic zinc carbonate will be formed on the surface, which can delay the corrosion rate of zinc layer. The corrosion resistance of galvanized layer in aqueous solution of acid, alkali and sodium chloride is relatively strong. It is also not resistant to corrosion in atmospheres containing carbon dioxide and hydrogen sulfide and in Marine atmospheres; In high temperature and high humidity air and containing organic acid atmosphere is small, galvanized layer is also easy to be corroded.
When a guided weight progress or repeated guided weight progress at a smaller height (driving) or left-handed and right-handed rope is used in pairs, ordinary wire rope can be selected. The determination of wire rope rotation should comply with: right-handed rope groove drum recommended use of left-handed wire rope: on the contrary, left-handed rope groove drum should use right-handed wire rope.
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.
A variety of arc, undivided Angle and undivided elevation ladder mounts are available to provide the ideal treatment plan. It can be used together with the appearance and the design of the common trackless active shift door, forming a harmonious and intact whole.
Pay attention to safety in line collection and operation, others without the consent of the monitor, Ben have to get on the bus operation. The reels should be placed lightly, stacked firmly and neatly, not more than 5 reels. Direct contact with acid and alkali must be prohibited. When the acid fog exceeds the specified target of the state, measures should be taken to control it in time, otherwise production is not allowed.
2. Adjust the drawing process parameters of the water tank
- With a large pickpocket used for steel wire, into the zinc liquid before the surface of the zinc ash stirring; Use a small outlet for galvanized steel wire; Zinc pot steel wire outlet in 30 minutes, with pickpockets back and forth, until the large, floating zinc residue into brown, real zinc ash, zinc ash surface. The extracted zinc ash should be brown yellow real zinc ash, zinc surface, effectively reduce zinc consumption. This is one of the measures to reduce zinc consumption, but it is also a real problem, which has not been solved for many years.
There are two varieties of steel grid plate is pressure welded steel grid plate and pressure lock steel grid plate, in many people’s eyes, these two products belong to the same variety, in fact, there are still great differences between them in many places.

Post time: 20-09-22- 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.
- National standards on the use of wire mesh standards have certain requirements, diameter and mesh size matching use, rather than simply diameter size, on the plaster layer to use is mesh should not be greater than 20×20, diameter is not easy to be less than 1mm, light selection diameter is not much significance, choose 40×40×0.9 and choose 10×10×0.6 wire mesh, Which one is better? 10×10×0.6, I’m afraid.
