Product Introduction:

1.HRB335 steel bars refer to steel bars with a strength grade of 335 MPa, where Hrb represents its hot rolling process and 335 represents its strength grade. These letters and numbers are usually printed on the surface of the steel bar. HRB335 (20MnSi) steel bar has a standard yield strength of 335 MPa and a diameter of 6-50mm, elastic modulus is 200 MPa.
2.HRB335 reinforcement performance
1). HRB335’s reinforcement performance is that the tensile strength is better than 420MPa, the pressure resistance strength is not less than 290MPa, the elastic modulus is not less than 200GPa, and the extension rate of the plastic strain ratio is not less than 15%. Not less than 60%.
2). HRB335’s reinforced diameter
HRB335’s steel bars use detail technology. The diameter of the reinforcement circle is specified as ChinaΦ6, Φ8,Φ10, Φ12, Φ14, and Φ16mm, etc., and the inner diameter of the reinforcement used is More than 10%, the internal diameter deviation rate must not exceed 3%.

Application

1. Construction engineering: The application of thread in the field of construction is very wide. It is often used for reinforcement and enhancement of reinforced concrete structures, such as stairs, pillars, beams and floors. The high -strength and good plasticity of the thread make it an indispensable material in construction engineering.
2. Bridge engineering: In the construction of the bridge, threaded steel is often used to make key parts such as steel concrete pier, bridge and beams. Because the thread has excellent tensile strength and durability, it can withstand a large number of loads and deformation, so it should be extensive in the bridge engineering
use.
3. Tunnel engineering: Steel also plays an important role in tunnel engineering. It is often used to make the wrong rod anchor and steel beam in the tunnel support structure. Because tunnel engineering has high structural strength and stability, the high strength and durability of the nut have made it the preferred material.
4. Foundation engineering: In foundation engineering, threaded steel is often used to make underground continuous walls and basement reinforcement walls and underground pipe galleries.
Steel steel has good plasticity and seismic performance, and can effectively improve the stability and bearing capacity of the structure.
5. Infrastructure engineering: Steel is also widely used in various infrastructure projects, such as docks, ports, dams, etc. It is often used to make the wet embankment, the retaining wall and the support structure, which can resist the impact of water flow, waves and geological power, and ensure the safety and stability of infrastructure.
