Donghua Iron & Steel is tirelessly pursuing the production advantages and technical advantages in the field of high-strength rebar manufacturing. The company not only has φ5.5-50MM full range of rebar production qualifications, but also can produce HRB400, HRB400E, HRB500, HRB500E and other φ5.5-55MM full range of high-strength anti-vibration rebar, and has the technical advantage of 1000Mpa high-strength rebar. On the basis of quality and quantity, we will improve the production capacity of rebar as our professional mission. At present, our high-strength rebar is widely used in construction, engineering, bridges and other fields, and has been well received by customers.
1, high anti-corrosion performance, can be a large number of safe reserves.
2. Among the chemical components, the welding performance is good due to the low carbon equivalent of the new grade III rebar.
3, high yield ratio, in line with seismic performance requirements. Especially suitable for high-rise buildings and projects with high seismic performance requirements.
4, excellent cold bending performance, can be repeatedly bent, more in line with and meet the processing requirements in construction.
5, due to the high strength can reduce the amount of steel used, effectively solve the problem of excessively dense steel bars, easy to concrete watering. At the same time, it also reduces the cost of steel transportation and on-site processing.
