HRB400/HRB400E Deformed Steel Rebar

HRB400/HRB400E Deformed Steel Rebar
HRB400 is a steel reinforcement material with high strength and good plasticity. HR stands for "hot rolling", which essentially refers to the heating and rolling process of steel bars in the production process. B represents that its yield strength is 400 megapascals (MPa) higher than that of ordinary carbon steel. HRB400 steel bars are mainly composed of alloys of carbon, sulfur, phosphorus, manganese and other elements, which have weather resistance, corrosion resistance and high tensile strength.

Product Description

HRB400/HRB400E Deformed Steel Rebar Description

1. High strength: The yield strength of HRB400 steel bars is 400 MPa, which has higher strength and tensile properties compared to general carbon steel, and can effectively increase the bearing capacity of concrete components.
2. Good plasticity: HRB400 steel bars have good toughness and elongation after being subjected to stress, and can maintain high strength even if bending and deformation occur.
3. Good welding performance: HRB400 steel bars have good weldability and can be welded with other steels, making them convenient for use in construction.
4. Weather resistance: HRB400 steel bars have good weather resistance and can be used for a long time in harsh weather conditions, making them less susceptible to oxidation and corrosion.
5. Simple construction: The shape of HRB400 steel bars is relatively simple, usually flat or circular, which is convenient for processing and use.
