The height of the shield should not be less than two meters. The length of the shield should be the width of the journey and the extension 10 meters away. The vertical load of the handrail on the bridge is 1.2KM/m, and the horizontal external load is 2.5KM/m, both of which should be calculated separately. Galvanized hook mesh belongs to a hook mesh, it is the selection of galvanized wire, hot-dip galvanized wire as raw materials, woven through the hook mesh truncated.
Temporary rust prevention is to prepare for the completion of the mission of the protective layer to be removed. The methods include: cajoling corrosion inhibitors, coating antirust oil, peeling molecular compound plastics, drying air, vacuuming, etc. Change the internal structure of the metal: new chromium, nickel and other alloy elements made of stainless steel, but the alloy is not much, expensive, difficult to produce widespread application.
When laying steel wire mesh, according to the laying method from the middle to both sides in turn. Wall plastering engineering use wire mesh material is generally two kinds: one is electroplating, the other is hot dip galvanized. The former has low cost and a wide range of use. The cost of hot-dip galvanized material is slightly higher than that of electroplating, and the cost is high and the life is good to prevent rust. Hot dip galvanizing is in the case of heating plating. After the zinc is melted into liquid form, the base metal is immersed in it so that the zinc interpenetrates with the base metal and binds so tightly that there are no other impurities or defects left in the process.
Razor wire, also known as razor wire and razor net, is a new type of protective net. Blade barbed rope has beautiful, economical and practical, good resistance effect, convenient construction and other excellent characteristics.
There are many categories of large rolls of galvanized wire, and different categories can be applied to different scenarios. The common application of galvanized iron wire is the application of the construction industry. One is the use of binding wire. Whether it is the binding of scaffolding or reinforcement, galvanized iron wire is needed to carry out. There are also 20kg or 50kg bundles of No. 18, No. 16, No. 14, No. 12, No. 10 galvanized coils.
Solder spot, size and wire diameter of galvanized electric welding net. There are clear regulations about size and diameter of silk, as long as it meets the standard, there will not be too much difference. Galvanized welding net production is mainly welding, welding point is firm directly determine the quality of the net. Large galvanized wire purchase process need to carefully observe the solder joint, if the solder joint is too shallow, it shows that the welding is not so strong, it is easy to open welding after use.
The methods to control the thickness of galvanizing are as follows: you can slow down the lifting speed of the workpiece, control the time of galvanizing as far as possible, add the appropriate amount of thinning alloy, reduce the thickness, and improve the temperature of hot-dip galvanizing. But consider the zinc pot, iron pot should not exceed 480 degrees, ceramic pot can be 530 degrees, which can reduce the time of zinc immersion.
Construction welding net work wall insulation project using galvanized welding network in wall insulation and rust engineering project plays a necessary role, wall painting batch putty network is divided into two kinds: this is galvanized welding network; Another is to change the wire drawing wire welding mesh, according to the provisions of the region, construction enterprises to carry out effective material selection. Construction welded wire mesh new mink cage new mink cage grommet see more 1 inch, from silk in 2 mm up and down, management method is simple and easy, a mesh surface bright and clean and is not easy to scratch mink, galvanized welded wire online zinc quantity proportion, it is not easy to rust, new mink cage up more convenient, mink settled in natural environment more comfortable, the price also is higher than before the same specifications of the mink cage competitive many, But the overall character is not harmed at all, it is stronger.
Wire flexibility and elongation is good, can withstand the pressure of mechanical operation, in our country’s industry has played a very important role. There are many kinds of iron wire, the most common is to give black iron wire, galvanized iron wire. The corrosion resistance of the outer coating is effectively improved, but the phenomenon of crevice corrosion will be found after long-term use.
Because the coastline is generally erected for protection, but often because of environmental factors lead to serious corrosion of the barbed rope lost its function. Stainless steel barbed rope is specially set up to prevent corrosion. Stainless steel barbed rope because the environmental requirements are not very high can be very good protection itself will not have a problem to extend the use of life, so that you can ensure safety.
For the barbed rope products produced by the barbed rope factory, the number of rotating turns between the two thorns is usually 3-5. What is the internal relationship between this and the length of use?
