HRB400/HRB400E Steel Wire Rod 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.
Mechanical Properties
Key Features
- High strength: Yield strength of 400 MPa significantly increases the load-bearing capacity of concrete structures while reducing steel consumption.
- Excellent weldability: Suitable for all common welding processes including flash welding, arc welding and pressure welding.
- Good ductility and bendability: The steel bar can be bent and processed on site without cracking, simplifying construction.
- Seismic performance (HRB400E): The "E" grade offers guaranteed elongation and strength ratio for earthquake-resistant design.
- Corrosion & weather resistance: Stable surface finish that withstands harsh environments during storage and transport.
Applications
HRB400/HRB400E steel wire rod is widely used in reinforced concrete structures: high-rise buildings, bridges, highways, tunnels, dams, industrial plants and precast concrete components. It is also the raw material for rebars, mesh and other concrete reinforcement products.
Available Sizes
Quality & Packaging
Each batch is supplied with a mill test certificate and can be inspected by third-party agencies such as SGS, BV or TUV. Packaging: bundles wrapped with steel strapping, seaworthy export packing, or per customer requirements.
