Usage and Applications of GB Standard HRB400 Steel Deformed Bar 28mm/32mm:

 

Deformed bar is widely used in buildings, bridges, roads and other engineering construction. Big to highways, railways, bridges, culverts, tunnels, public facilities such as flood control, dam, small to housing construction, beam, column, wall and the foundation of the plate, deformed bar is an integral structure material. With the development of world economy  and the vigorous development of infrastructure construction, real estate, the demand for deformed bar will be larger and larger.

 

Packaging & Delivery of GB Standard HRB400 Steel Deformed Bar 28mm/32mm:

Packaging Detail: products are packed in bundle and then shipped by container or bulk vessel, deformed bar is usually naked strapping delivery, when storing, please pay attention to moisture proof. The performance of rust will produce adverse effect.

Q:What is the national standard of thread steel No. 8?
Thread steel specifications: generally including the standard grade (type code), steel nominal diameter, nominal weight (quality), the length of the specifications and the allowable difference between the above indicators. China's standard recommended nominal diameter of 6, 8, 10, 12, 16, 20, 25, 32, 40, 50mm thread steel series.
Q:Are steel bars used more in high-rise buildings or steel?
The shear wall structure is used in many round bars, such as vertical wall bars, horizontal bars, steel bars and stirrups. Note that only general structures are concerned.
Q:What are the main use of threaded steel?
Steel is usually used for reinforced concrete, its role is to increase the friction fringe, the rebar and concrete secant integrally formed together, tic phenomenon can not occur in the role of external force, improve the strength of concrete.
Q:What is the difference between the II and III grades of threaded steel?
Compared with traditional II grade steel, the characteristics are as follows:1, high corrosion resistance, can be a large number of security reserves.2. In the chemical composition, because of the low carbon equivalent of the new third grade steel, the welding performance is good.3, high strength ratio, meet the seismic performance requirements. Particularly suitable for high-rise buildings and high seismic performance requirements of the project.4, cold bending performance is good, can be repeatedly bent, more in line with and meet the construction requirements of the construction.5, because of the high strength, can reduce the use of steel, effectively solve the problem of reinforcing steel bars too close, easy to concrete pouring. At the same time, it also reduces the cost of steel transportation and on-site processing.
Q:What is the difference between three - grade steel and two - grade steel?
Therefore, in the future, the three grade rebar will be widely used, in addition, anti seismic (with E mark) thread steel will also be widely used in our daily life.
Q:Do l 8, three grade steel have discs?
Yes, but because of the higher grade of the three screw thread, they are straight bars. It's not necessary to use grade three for 8 mm.
Q:4E DG 164 is a steel grade 3 steel, DG steel, E is what mean
4 means HRB400, that is, hardness.E stands for seismic reinforcement.DG is da-gang.16 is the diameter 16mm.
Q:The effect of adding alum on thread steel
If the steel is a tiger, so is the wing steel containing vanadium vanadium, like the tiger wings. Only a few percent of vanadium in the steel, can make the elastic strength of steel, increase abrasion resistance and spalling resistance excellent, high temperature resistance and resistance in the car, no wonder the bitterly cold, aviation, railway, electronics, defense industry and other departments, can be seen everywhere traces of vanadium. In addition, vanadium oxide has become one of the best catalysts in the chemical industry, called vanadium, the "chemical bread". Mainly used in the manufacture of high speed cutting steel and other alloy steels and catalysts. The vanadium doped vanadium steel can be made into steel. A more compact structure than ordinary steel vanadium steel, toughness, elasticity and higher mechanical strength. Preparation of vanadium steel penetrators, can penetrate 40 cm thick steel plate. However, in the iron and steel industry, is not the pure metal vanadium steel to make vanadium steel, the vanadium ore smelting vanadium steel.
Q:What is hot rolled coil? Hot rolled coil relative to thread steel and other steel, is not considered a higher point?
The thread steel is a long piece of steel pulled out at a certain temperature.There is no high or no advanced problem between the two.
Q:What are the specifications of thread steel?
Thread steel small specifications of 101214, in the specifications of 1618202225, large specifications of 2832, size, specifications, in general, in accordance with the specifications on the basis of 20-100 yuan, if the larger 364042.It is a smaller disk 6.5810, because too small easy to bend, so the coiled coil shape, called disk.
