Q:Are steel bars used more in high-rise buildings or steel?
Look at the architectural design requirements and seismic grade, light steel reinforcement is mainly stirrups, columns, beams, shear walls generally use thread steel, plate bars and distribution bars are generally cold and twisted steel bars
Q:JL32 is the finish thread heavy bar 32? What's the difference between normal and ordinary? What does the front JL32 mean?
Finishing rolling rebar strength than ordinary ribbed steel bars to be high, with spiral thread, tension nut after solid increase concrete prestressed (equivalent prestressed steel wire, steel wire type).
Q:12 of the threaded steel can replace 16 of the screw steel? But the same proportion. Thanks
12 of the screw steel, rice weight is 0.89kg/m, 16 of the screw steel, rice weight is 1.57kg/m, with 12 of the thread steel instead of 16 of the screw steel, to the same proportion, that in dosage will be more.
Q:How heavy can a 25 mm thread steel bear?
Hot rolled ribbed bar is divided into two levels, HRB335 (old No. 20MnSi), three HRB400 (20MnSiV, 20MnSiNb, old No. 20Mnti), four grade HRB500 three grade.
Q:What is the difference between three - grade steel and other grades?
1, different grades of steel (chemical composition is different). HRB335 grade steel is 20MnSi (20 manganese silicon); HRB400 grade steel bars are 20MnSiV or 20MnSiNb or 20MnTi etc.;2, strength is different, HRB335 grade steel tensile and compressive design strength is 300MPa, HRB400 grade steel tensile and compressive design strength is 360MPa.
Q:How much is the difference between the three grade thread steel and the two grade thread steel?
This is no fixed bar, probably in the difference between 50-150, the normal situation, but more or look at the supply and demand situation, there are two more expensive than three, the specific circumstances of specific analysis.
Q:What is the difference between three - grade steel and two - grade steel?
Two grade steel thread subway project a little more, three grade steel room building project a little more. In addition, the original use of two steel more, and now are promoting the new three grade steel, concrete structure among the application has been very common. Three grade thread steel used in beam column main reinforcement is more, two grade thread steel used in more stirrups, recently, the state also issued expressly eliminated HRB335 two grade steel and HPB235 high wire.
Q:What is the quality difference between round bar and screw steel?
Different shape. The outer surface of the round steel is smooth; the outer surface of the spiral steel has a spiral rib. 2. different production standards. In the current standard, round bar that HPB235 grade steel, and its production standards are "hot-rolled smooth steel reinforced concrete" (GB13013); rebar generally refers to HRB335 and HRB400 grade steel, its production standard is "the reinforcement of concrete hot rolled ribbed bar" (GB1499). 3. different strength. The design strength of round steel (HPB235) is 210MPa; the strength of thread steel is higher than that of round bar; the design strength of HRB335 is 300MPa; the design strength of HRB400 is 360MPa.
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:Why is round bar more expensive than thread steel?
Threaded steel should be used in the construction field, there are generally two, three grade steel, grade HRB335, HRB400 also has four grades, HRB500 thread steel.
