The Future Development Trend Of Cold Rolled Ribbed Steel Bars
As a kind of steel building material, cold rolled ribbed steel has a very broad application prospect, so many merchants will set up cold rolled ribbed steel bars factory. However, with the establishment of new national standards about the steel industry pubilished by the country and the provinces, municipalities and autonomous regions,the future development trend of cold rolled ribbed steel has also surfaced. So which aspect will the cold rolled ribbed steel be developed in the future?
According to the observation and understanding of Gongyi Jindi Metallurgical Equipment Co., Ltd, our company believes that the development of cold rolled ribbed steel will develop in the direction of high tensile strength and high yielding, ie high-strength steel.
The so-called high-strength steel bars refer to steel bars with tensile strengths up to 400 MPa. According to Jindi Metallurgical Equipment, CRB600 grades, CRB650, CRB650H, CRB800, CRB800H and CRB970 are five kinds of cold rolled ribbed steel bars. The tensile and yield strength is much higher than 400 MPa, which fully meets the standard requirements for high strength steel.
According to the national planning requirements, in 2013, it will accelerate the elimination of 335 MPa grade reinforced steel bars, and strive to prevent 235 MPa and 335 MPa steel bars from being used by steel companies in 2013, and priority to use 400 MPa high-strength reinforced steel bars and actively promote 500 MPa grade high strength steel. By the end of 2015, the output of high-strength ribbed steel bars of 400 MPa and above accounted for more than 80% of the total output of threaded steel bars, and the amount used in construction projects reached more than 65% of the total amount of reinforcing steel bars for construction.
Therefore, in this respect, the future development trend of cold-rolled ribbed steel bars is to develop toward high strength.
The cold rolled ribbed steel mill and cold-rolled ribbed steel production line produced by Gongyi Jindi Metallurgical Equipment Co., Ltd can fully meet the demand of CRB650 and CRB650H cold rolled ribbed steel with tensile strength of 430 MPa.
