Chengde Steel Company of Hebei Steel Group successfully developed 300 tonnes of 25mm HRB600 high-strength earthquakeproof rebar recently, with all indicators qualified. Henceforth, China itself can produce high-strength rebar of 600 MPa yield strength.
Developing high-strength rebar with fine comprehensiveness is an inevitable trend for future construction. The achievement of HRB600 high-strength earthquake proof rebar could reduce steel usage volume on the one hand.
Compared to currently prevailing HRB335, HRB400 and HRB500 rebar, the utilization on HRB600 could save steel usage volume by 73.3 percent, 44.4 percent and 19.5 percent, realizing a realistic significance of energy saving and emission reduction. On the other hand, this utilization could also enlarge usable floor area, adding more flexibility to structure design.
As a leading enterprise on producing rebar, Chengde Steel shoulders this responsibility itself
