Double-ended studs are commonly used in automotive and industrial applications. In the automotive industry, they are often used to secure engine components, exhaust systems, and other parts that need to be securely fastened together. In the industrial sector, double-ended studs are used in machinery, equipment, and structural applications
In addition to their mechanical advantages, self-drilling lag screws offer practical benefits too
- Wire mesh depend on own unique strengths are indispensable in building professional, reinforcing crack strengthening anti-cracking material, products with high degree of error is small, uniform mesh, mesh welding, accept ability is strong, not easy deformation, steel wire mesh in different fields have different called, people call it soft steel bar in bridge engineering construction.
- 2. The cleaning agent used for cleaning should have no effect on the binding force of the coating and no corrosion on the matrix.
- If the requirements are not high, and the ventilation is good, and relatively dry place, it is recommended to use electric galvanized barbed rope, because the price of this product has a certain advantage, for ordinary users, this is a more appropriate product.
Post time: 27-04-23Stainless STEEL HAS THE ABILITY to resist ATMOSPHERIC OXIDATION – that is, rust resistance, but also has the ability to resist corrosion in the medium containing acid, alkali, salt – corrosion resistance. However, the corrosion resistance of the steel varies with its chemical composition, additive state, service conditions and environmental media type.
- Of course, these are limited to the maintenance of the indoor balcony, so outdoor, some of this is less than maintenance, some maintenance will waste resources, because of the expected life, in order to ensure the safety of the role, timely update is good.
The wire mesh is composed of low carbon steel wire or medium carbon steel wire, high carbon steel wire or stainless steel wire. There are two kinds of manufacturing technology of steel wire mesh, one is the weaving method, the other is the welding connection, the formation of grid.
Stainless steel hexagonal network is composed of machine will be produced stainless steel wire of a kind of metal mesh, not easy corrosion, the survival of the fixed number of year is longer, net of wide, coarser size, strong practicability, flexibility and other unique places, stainless steel hexagonal wire netting material is stainless steel wire, wire diameter because stainless steel wire big viscosity of large stainless steel hexagonal network would be hard to manufacture, Of course, it is more difficult to hold the edge or twist the edge, so stainless steel hexagonal mesh whether from the material or artificial are expensive, but stainless steel hexagonal mesh will not rust and use years is also very long, appearance without disposal can achieve the use effect.

- 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. Now a lot of hardware manufacturers are producing iron wire, and the iron wire is very easy to rust, if you need to use in outdoor or humid places, the general customer will require the use of galvanized iron wire equipment to give the wire a layer of zinc, the thickness can be determined according to user requirements.
- Atmospheric relative humidity At the same temperature, the percentage of atmospheric water vapor content and its vapor saturation content is called relative humidity. Below a certain relative humidity, the corrosion rate of metal antirust oil is small, while above this relative humidity, the corrosion rate increases sharply.
The characteristics of galvanized hexagonal net: easy to use; Save transportation costs. It can be shrunk into small rolls and involved in moisture-proof paper packaging, taking up little space. Coating thickness uniformity, stronger corrosion resistance; The construction is simple and does not require special technology; Strong resistance to natural damage and corrosion resistance and adverse weather effects; Can withstand a large range of deformation, and still not collapse. It has the function of fixed heat preservation and insulation.
Stainless steel barbed rope in the way of corrosion is not very, because the surface is not treated but rely on its own raw materials for corrosion resistance, so there will be no chemical reaction.
The diameter of cold-drawn wire should conform to the contract, check whether the amount of zinc meets the requirements of the contract, check the tensile strength, and ask the factory to provide the corresponding inspection report. The wire factory introduces that the weight of a single coil of wire of different specifications should not be lower than the volume weight required by the contract, and record the value. 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.
- 3, pasture installation of barbed rope column to choose strong impact resistance zinc column, and coupled with oblique column fixed. Due to the large size of livestock, although there is a barbed rope to deter but inevitable collision phenomenon, in order to the stability of the fence recommended to use zinc steel post.
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.
Post time: 27-06-22Cold galvanizing is in the plating tank through the current unidirectional zinc gradually plated on the metal appearance, the production speed is slow, uniform coating, thin thickness, usually only 3-15 microns, bright appearance, smooth, high aesthetics, poor corrosion resistance, generally a few months will rust. Hot dip galvanized coating is thicker, generally 30-60 microns, coating corrosion resistance is higher. Suitable for outdoor work of steel parts, such as highway fences, power towers, large size fasteners and other more “rough” workpiece long-term rust prevention.
- Deoxygenation of boiling steel is incomplete, oxygen content is high, phosphorus and other impurities distribution is uneven, local overspending, aging sensitivity and cold brittle sensitivity are high, hot cracking tendency is added. If unqualified electrode is used, if the content of carbon and sulfur in the weld metal is too high, cracks will occur. For example, when factories use acidic electrodes to weld Q235-A steel, the high carbon fernoganese in the electrode coating will lead to thermal cracks in the weld.
- Hexagonal cage has a wide range of applications, with the progress of science and technology, has been extended to the major hydraulic engineering, civil engineering. Geotechnical engineering and other projects. In the hydraulic hexagonal cage in the river construction to reach the utility, that is appropriate and the use of hexagonal cage used to fill stone, fixed river, can avoid river erosion bring water and soil loss. In the civil engineering project, the hexagonal cage is considered appropriate and the use of similar particle size volume particle filling, cage between the formation of a mesh wall, which is the stone cage mesh retaining wall.taining wall.
In order to remove the photosynovium and oxide remaining on the surface of galvanized iron wire after drawing or heat treatment, it is necessary to do the surface treatment of galvanized steel wire before plating. The common surface of low carbon steel wire is the light synovium or oxide of animal or vegetable oil; Medium and high carbon steel in addition to contain animal or vegetable oil components.
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.
- 1, first of all, the net surface is smooth, mesh are four lines, pitch is the same, whether the weft wire bending (note: the net width is the length of the weft wire), normal weft wire passes through the straight wire of welded wire mesh, with accurate time and the silk repeated welding, make the pitch of welded wire mesh is consistent, with smooth surface, into a square hole, when the net vertical position from the top downwards see, weft wire is straight.
First, the concept is different
Galvanized wire in acid, alkali, sodium chloride aqueous solution of poor corrosion resistance, in the atmosphere containing carbon dioxide and hydrogen sulfide, as well as Marine atmosphere is not corrosion resistance. In high temperature and high humidity air and containing organic acid atmosphere is small, galvanized layer is also easy to be corroded. Galvanized wire and general wire is very different, general wire is cheap, and because the iron is not very stable, easy to rust in the wet place, so the stability is not very good, the life is not very long.
- C, coating uniformity: galvanized layer is basically uniform with copper sulfate solution test etched five times without exposing iron.
- 2, mesh, mesh also directly affects the price of the stone cage net
