Concrete form wedge bolts are specialized bolts designed for use in concrete formwork systems. They typically feature a tapered design that allows for easy insertion and a secure grip once fitted. The wedge shape creates a locking mechanism that holds the formwork in place, preventing it from moving during the pouring process. These bolts are often made from high-strength steel to withstand the pressures and forces exerted by wet concrete, making them reliable for various construction applications.
Moreover, their anti-corrosive properties ensure they remain rust-free, maintaining their strength and integrity over time, especially in outdoor applications Moreover, their anti-corrosive properties ensure they remain rust-free, maintaining their strength and integrity over time, especially in outdoor applicationsself drilling screws for upvc.
The difference is that hot dip galvanizing is dipped in zinc solution melted by heating, which has fast production speed and thick but uneven coating. 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. Cold galvanized is in the plating tank through the current unidirectional zinc gradually plated on the metal surface, the production speed is slow, uniform coating, thin thickness, usually only 3-15 microns, bright appearance, poor corrosion resistance, generally a few months will rust.
1. Eliminate caked zinc residue on zinc liquid surface
The fence effect of the barbed wire installation can be recognized by the majority of customers, its advantages are as follows: First of all, for some of the original protective device barbed wire because of the convenience of installation, the installation process is very simple, only need to fix the barbed wire column, and then gradually install the barbed wire according to the hook on the barbed wire column.
Plastic-coated barbed rope is not only used but also beautiful, so it is used in a large number of highway sides, and other special places, so what are the colors of plastic-coated barbed rope? Where are the plastic-coated thorn ropes of no color respectively applied?
Wire mesh first welding after galvanized is through the end of welding and then cold this company to produce wire mesh wire mesh steel mesh construction mesh floor heating mesh galvanized or hot dip galvanized. First galvanized after welding is to change wire mesh, after the end of welding can see the solder joint; The two processes are different in price. The cost of plating after welding is low, the appearance is smooth, and the cost of plating after welding is high, and it is not easy to rust.
Galvanized wire mesh is divided into hot dip galvanized wire mesh and cold galvanized wire mesh. Galvanized steel wire net selects the high quality low carbon steel wire, iron wire factory made by precision of automation machinery welding technology processing, smooth surface, firm structure, integrity is strong, even if the local cutting of galvanized steel wire net, or local also under pressure from loose phenomenon, after molding, wire mesh galvanized corrosion resistance good, has the advantage that the general steel mesh does not have.
Compared with the traditional braided and twisted barbed rope, the price of raw materials is relatively high because of the relatively complex technology.
Pet cage has many types, and selective is bigger, pet cages are generally made of wire, with better coarse, then at the bottom with a wheel base, such a simple pet basket was made, in the wheel at the bottom of the mount is for the convenience of the mobile, a pet cages should also adapt to the location of the production in addition to a door, It is convenient for feeding pets.
The external environment has a great influence on the storage of cold drawn wire. Especially during the rainy season, special attention should be paid to the air humidity of workshops and warehouses. It is recommended to use moisture test paper with a value between 8 and 10. If the PH value is high, attention should be paid to the corrosion of the internal cold drawing wire. Cold drawing wire in normal environment storage for two years no problem, cold drawing wire will not be corroded. However, it is necessary to place the coil gently during the handling process to avoid the winding position leading to the cable is not smooth.
When large rolls of galvanized wire are used to bind and reinforce the goods, corresponding binding methods should be selected according to the fastening node conditions of the strengthened goods, such as opening binding, opening binding, insertion binding and so on. The insulation layer of semi-hard and soft insulation products shall be based on the diameter of the steel pipe and the size of the equipment. Large rolls of galvanized wire or glue are tied together with a width of 60mm. The binding interval of semi-hard insulating products shall not exceed 300 mm; The larger length of felt and cushion shall not exceed 200mm, and the number of belts shall not be less than 2.
For example, Przewalskopeles is a first-class protected animal in China. At present, as long as there are several other przewalskopeles populations around Qinghai Lake in China, according to incomplete statistics, there are only about 1,000 of them left. Stainless steel barbed wire fence net is commonly used in grassland pastoral area of Qinghai Lake, with a height of 1.5 meters.
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.
