Q:What is the quality difference between round bar and screw steel?
Different grades of steel (different chemical composition). Round steel (HPB235) is carbon steel, steel is Q235; thread steel is low alloy steel; HRB335 grade steel is 20MnSi (20 manganese silicon); HRB400 grade steel bars are 20MnSiV or 20MnSiNb or 20MnTi etc.;
Q:Why is thread steel thinner than crude?
Because the surface has a thread shape, it can increase the firm bond with the concrete. The longitudinal reinforcement and stirrups shall be used preferentially in the concrete members. Because the rebar is low alloy steel and its price is higher than that of low carbon round steel, the construction unit or design unit usually starts from the practical angle of the general civil building
Q:What is the national standard of thread steel No. 8?
Rebar national standard: transverse rib nominal spacing shall not be greater than 0.7 times the nominal diameter of steel, the cross rib side and the steel surface of the angle of alpha may not be less than 45 degrees. When the steel nominal diameter less than 12mm, the relative rib area should not be less than 0.055, the nominal diameter of 14mm and 16mm, the relative rib area should not be less than 0.060, the nominal diameter is more than 16mm, the relative rib area should not be less than 0.065. Therefore, the nominal diameter of rebar No. 8 national standard steel bar relative rib area shall not be less than 0.055mm
Q:What does "4esg25" mean on thread steel?
The brand of steel is expressed in terms of Arabia numerals or Arabia numerals plus English letters. HRB335, HRB400 and HRB500 are represented by 3, 4 and 5, respectively. HRBF335, HRBF400 and HRBF500 are represented by C3, C4 and C5 respectively. The name of the factory is expressed in Chinese phonetic prefix. Nominal diameter mm Arabia digital representation.
Q:Which is more expensive, rebar or round steel? Which is your business opportunity, such as thread steel and round bar?
Prices have been rising, customers have expressed that the purchase price increases, we will increase the cost of procurement, coupled with the pressure of funds, so we can not easily buy at the last minute.
Q:What are the different uses of wire rod and thread steel?
According to statistics, China's construction industry accounts for about 50% of the total steel consumption. As one of the resources consuming industries, the construction industry must adjust the consumption structure of construction materials, energetically apply high-strength steel bars and high-performance coagulation, and take the road of economical development. If the current use of steel and concrete to raise an intensity level, it can bring enormous savings to society. For example, by calculation, according to the standard requirements, if the reinforced concrete leading force steel strength increased to 400-500N/mm2, then can be in the current level of steel consumption to save about 10%.
Q:How to judge the quality of thread steel?
Use material tester to measure data, then compare with national standard data.
Q:12 of the threaded steel can replace 16 of the screw steel? But the same proportion. Thanks
Now Tianjin Tiantai into 12 of the price is 3900 yuan a ton, 16 tons of steel a price is 3850 yuan. 12 of thread steel is 50 yuan more expensive than 16 thread steel.
Q:Are rebar bars = rebar?
Rebar is only one of the reinforcing bars, and the reinforcing bars used in the construction site are distinguished from the appearance. They are mainly round steel (round steel bars) and plain steel (the appearance has lines, and the steel bars are divided into two kinds: thread and crescent).
Q:How many patterns are there in threaded steel?
There are two kinds of classification methods commonly used types of thread steel: one is to shape classification, according to different space shapes and transverse rib rib for classification or type, such as the British Standard (BS4449), the thread steel is divided into type I and type ii. This classification mainly reflects the tightening performance of the threaded steel. The two is the performance of classification (class), such as China's standard (G B1499), according to the strength (tensile strength yield point / steel) will be divided into 3 levels; the Japanese industrial standard (JI SG3112), according to the comprehensive performance of steel will be divided into 5 categories; the British Standard (BS4461) also, certain provisions of the grades of steel performance test thread. In addition, the thread steel can be classified according to the use, such as reinforced concrete, ordinary steel bars and reinforced concrete bars for heat treatment. Main uses: widely used in housing, bridges, roads and other civil engineering construction.
