In addition to material compatibility, the design and installation of aircraft structural fasteners are also critical factors in ensuring the integrity of the aircraft. Fasteners must be properly torqued to the manufacturer's specifications to ensure that they provide the necessary clamping force to hold parts together securely Fasteners must be properly torqued to the manufacturer's specifications to ensure that they provide the necessary clamping force to hold parts together securely
In addition to their time-saving and versatility, self-drilling screws also provide a strong and secure hold
Moreover, hex timbr screws are made from high-quality steel, which ensures they are both durable and resistant to corrosion
- The diameter of the wire is generally 0.3mm – 3mm, after the wire is not very strong, need to annealing, annealing this step is very important, can ensure the production of galvanized welding net, with good elasticity and toughness. After welding, the welding mesh becomes black wire welding mesh and can not be put on the market, because its corrosion resistance is poor and the service life is short, so it needs to be galvanized or dipped plastic treatment.
- 2. When the weather is too dry and humid, remember to blow dry the cage or move it to a place with heating to prevent dry crack damage.
Large roll galvanized wire is like the literal meaning, is wrapped in a layer of zinc on the surface of low carbon steel wire material, beautify the appearance at the same time, but also improve the corrosion resistance of galvanized wire. Zinc dissolves easily in acids and alkalis, so it is called a dissoluble metal. Zinc changes little in dry air. In moist air, a dense basic zinc carbonate film forms on the surface of zinc.
- Appellation: Hook fence net is a variety of fence net. The diameter of the opposite side of each mesh is generally 6.5cm-14cm. The diameter of the wire used is generally from 3.5mm to 6mm. Wire material is generally Q235 low carbon wire. The iron wire is welded into black pieces of decorative hook mesh by ginning. The overall size of the mesh is 1.5 m X4 m, 2 m X4 m, 2 m X3 m. The general surface treatment is cold (electric) galvanized treatment. There are also hot dip galvanizing, dipping, spray. But overall, 99 percent is cold (electric) galvanized.
- The reason why there are black spots in wire mesh welding is that the action of wire feeding should be timely filled in the melting time, and the development should be appropriate. There is no argon gas, long burning, large current, long distance, blunt tungsten needle and high molten pool temperature are the fundamental reasons for blackening. Continuous burning, is about active welding machine energy selection, machine welding will appear black spots.
- Carbon steel wire is basically do not participate in alloying elements of high carbon steel wire, but also in the low cost of steel wire, hot and cold processing is outstanding, the use of a wide range of steel. Spring steel wire contains high carbon steel wire, high carbon steel wire is the spring steel wire in between.
After the column is installed and secured, the net can be connected directly to the Internet. The tools required for this step must be special spanner, casing and matching screws. Stand the net in the middle of the two columns, and then force upward to align the net with the connecting accessories of the column.

Post time: 23-03-23Titanium alloy with low carbon content is obtained because the carbon content remains the original concentration. The hardness of titanium alloy is mainly related to its carbon content. Therefore, after carburizing and subsequent heat treatment, the workpiece can obtain the performance of hard and tough inside. Galvanized wire varieties are mainly classified into three categories: electric galvanized wire, hot galvanized wire and galvanized wire. Among them, the classification of galvanized wire is divided into large roll galvanized wire, medium roll galvanized wire, small roll galvanized wire, galvanized shaft wire, truncated galvanized wire and other main production varieties.
Hot dip galvanizing, also known as hot dip galvanizing, is a method of obtaining a metal covering layer by immersing a steel member into a molten zinc solution. With the rapid development of high-voltage power transmission, transportation and communication, the protection requirements for steel parts are becoming higher and higher, and the demand for hot-dip galvanizing is also increasing. Usually the thickness of electrogalvanized layer is 5 ~ 15μm, and the large roll galvanized wire layer is generally more than 35μm, or even up to 200μm. Hot dip galvanized coating ability is good, dense coating, no organic inclusions.
As we all know, the use of hexagonal net protection, can protect the natural environment while protecting the bridge, so as not only to green the ecological environment, but also to prevent soil erosion.
2. Stainless steel 316 material should be used in coastal areas, which can resist corrosion of sea water.
Post time: 09-10-22- 5, according to the wire diameter thickness to adjust zinc dipping time
Hardness is a commonly used property index in mechanical properties of metal materials. The iron wire factory introduces a fast and economical test method for hardness testing. However, for the hardness of metal materials, there is not a unified and clear definition including all test methods at home and abroad. In general, the hardness of a metal is often considered to be the resistance of the material to plastic deformation, scratches, wear, or cutting.
1. Used for mountain farming, road isolation, large farming enclosure protection, it is recommended that you choose 3mm wire diameter products.
Post time: 19-05-23- 3. The transport, storage and use of the binder of galvanized wire mesh should adopt safety and fire prevention methods according to the relevant regulations, so as to be safer.
The large roll of galvanized silk should be coated with oil, the fiber core is dipped in oil, and the grease should be able to protect the fiber core from decay and corrosion, the iron wire moistens the fiber, and lubricates the wire rope from the inside. The surface is coated with oil so that all the wire surface in the rope strand is evenly coated with a layer of anti-rust lubricating grease, which is used for the mine rope with friction lifting and mineral water, to be coated with black grease with increased wear and strong water resistance. Other uses are coated with red oil oil with strong film and good rust resistance, and require it to have a thin oil layer, which is easy to keep clean during the operation.
Some customers are more concerned about quality problems, so for the service life is more important, barbed rope factory will generally recommend the use of high zinc barbed rope or stainless steel barbed rope.
The antisepsis of these materials is very different, the use of life is not the same. Cold galvanized cattle net, also known as electroplating, galvanized amount is small, rust in rain, but the price is cheap, the service life is 5-6 years. The amount of zinc on hot dip galvanizing (low zinc and high zinc) is about 60g to 400g, the service life is about 20-60 years, and the corrosion resistance is general.
Post time: 03-01-23Hot dip galvanizing is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. Hot dip galvanizing is to first pickling the iron and steel parts. In order to remove the iron oxide on the surface of the iron and steel parts, after pickling, it is cleaned in the tank of ammonium chloride or zinc chloride aqueous solution or mixed aqueous solution of ammonium chloride and zinc chloride, and then sent into the hot dip plating tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.
