Using a thread drill bit requires a delicate balance between force and finesse
One of the key advantages of a hand jack hammer over its pneumatic or electric counterparts is its portability. With no cords or air hoses to limit your movement, you can take this tool anywhere, making it perfect for on-site jobs or remote construction projects With no cords or air hoses to limit your movement, you can take this tool anywhere, making it perfect for on-site jobs or remote construction projects
Ordinary installation of blade thorn rope on the wall and the height of the wall in two meters up and down the general construction costs in a dozen yuan a meter, but if it is said that the height of the prison construction ordinary wall has reached four or five meters so that the construction cost of each meter is about 30 or 40 yuan, mainly because of high altitude operation risk degree is relatively large reason. The construction cost is different, but the price of blade thorn rope is the same, often the construction cost is higher than the product, which is the thorn rope factory recommends customers to use better quality blade thorn rope, which eliminates the cumbersome time and cost of subsequent demolition and installation.
Post time: 05-05-23The temperature of large roll galvanized wire should be controlled at 30 to 50℃ during electroplating. Because the chloride ions in the bath are very corrosive, quartz glass heaters are generally used. Continuous production does not need heating, but needs cooling. Cooling can be in the groove side row thin wall plastic pipe, through the flow of tap water cooling, can also be used as a titanium pipe temperature control device.
- The steel mesh improves shock resistance and crack resistance. The longitudinal and transverse steel bars of the welded steel mesh constitute a network structure. Therefore, the bond anchorage between the steel mesh and concrete is good, and the load distribution is uniform, which significantly improves the earthquake resistance and crack resistance of the reinforced concrete structure. According to the practice test, the cracks of welding net are reduced by more than 75% than that of manual binding net. Greatly reduce the unnecessary cost of the construction process, shorten the construction cycle, the use of steel wire mesh is simple and convenient, easy to transport.
Under any application environment, users hope that the welding mesh has better strength, as long as it has improved in strength, it will make better use of the demand, but to make the strength of this product improve, also need to have many conditions, to see what kind of data manufacturers have in production, the strength of the product is the strength of the data, But a manufacturer does not meet the strength requirements in the data, and naturally, it cannot make the strength of the product improve after all, so this is the condition.
At present, there are two main kinds of electric galvanized wire products, hot dip galvanized wire and electric galvanized wire. The difference is that the way of galvanizing is different, and the quality of the products is different. Hot dip galvanized wire zinc layer thick, corrosion resistance is stronger, but correspondingly, the price is high. Galvanized wire zinc coating thin, corrosion resistance is poor, but the price is low.
- The positive and negative twisting of barbed rope is less than 3 cents per meter, and the corresponding 12 hot-dip galvanized barbed rope is 50 cents per meter. No matter from the service life, tensile strength, rust prevention effect is no worse than 12 iron wire
- Packaging and binding electric galvanized wire is in the state of liquid zinc, after messy physical and chemical effects, not only on the steel plating thicker pure zinc layer, and also generate a zinc – iron alloy layer. This plating method not only has the corrosion resistance characteristics of galvanized wire, but also has a zinc-iron alloy layer. It also has strong corrosion resistance that can not be compared with galvanizing. Therefore, this plating method is especially suitable for all kinds of strong acid, alkali fog and other strong corrosion environment.
Using activated carbon mat to remove surface active substances, or through filtration to make the foam is not too stable, this is an effective measure; Other measures should also be taken to reduce the amount of surfactant introduced to Z.
- In use, it can be well used in the annealing process to control its degree of hardness, mainly used in the construction industry for binding silk and tying. Its use is certainly not limited to arts and crafts. It is also widely used in the construction industry. Earlier woven lanterns were made of wire, and inside were placed suitable candles, which were hung in front of the door. It was very beautiful to go up at night.
Cattle net in the outdoor use of a long time will inevitably show rust corrosion, this time the use of cattle net life depends on the maintenance of the product is not in place, we all know that cattle net if long exposure to harsh environment, the service life will be greatly reduced. How long does a normal cattle net last?
Heavy hexagonal mesh is made of steel wire woven into hexagonal mesh by special machinery. This kind of mesh, after cutting and assembling, can be made into fence mesh, mountain hanging mesh, vegetation three-dimensional mesh, assembly, etc.
Post time: 06-09-22- 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.
Hot dip galvanizing is dipped in zinc liquid melted by heating, with fast production speed and thick but uneven coating. The market allows a low thickness of 45 microns and a high of more than 300 microns. The color is dark, the consumption of zinc metal is much, the formation of infiltration layer with the matrix metal, the corrosion resistance is good, and the outdoor environment of hot dip galvanized can be maintained for decades. Application range of hot dip galvanizing: because the coating is thicker, hot dip galvanizing has better protective performance than electric galvanizing, so it is an important protective coating for iron and steel parts in harsh working environment. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, power transmission, shipbuilding and other industries, in the field of agriculture such as sprinkler irrigation, greenhouse and construction industry such as water and gas transmission, wire casing, scaffolding, Bridges, highway guardrail and other aspects, has been widely used.
3. Quality test report
- The smaller the mesh of decorative hook mesh, the finer the demand wire, the larger the mesh, the thicker the demand wire. For example, 6.5cm mesh aperture, the required iron diameter is 3.5mm-4mm. Then a fine welding will be broken, and then thick and heavy, workers can not bear.
- In this temperature range, the zinc solution is severely corroded to the workpiece and the zinc pot, and the iron is lost at 560 degrees Celsius to add obviously, and the zinc will be the iron substrate above 660 degrees Celsius, zinc slag will be added quickly, plating cannot be used. Therefore, electroplating is carried out in the range of 430~450 degrees Celsius.
- 3, a wide variety of specifications, a variety of shapes you choose, both European and American style and today’s popular fashion, full noble and modern beauty.

Post time: 10-02-23The tensile strength of cold drawn spring steel wire is slightly higher than that of oil tempered steel wire. The large specification of cold drawn steel wire elastic force is too large, winding the spring is very difficult, so the cold drawn spring steel wire application specification is generally less than 8.0mm, oil quenching tempered steel wire application specification is generally less than 13.0mm. In fact, the diameter of 13.0mm spring is used to light tension spring steel wire, cold drawing wound made into shape and then quenched and tempered. Steel wire with diameter above 15.0mm is mostly made by heating winding process.
Blade barbed rope production links need to be many times before the finished product, roughly down to four or five links.
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.
