Welcome to Hemaokang Steel (Shandong) Co., Ltd., your reliable partner in high-quality steel products. Our GB1499.2 HRB500 Deformed Steel Bar in diameters 12mm, 16mm, and 20mm is engineered to deliver exceptional strength with a guaranteed tensile strength of 500MPa. Designed for demanding construction projects, this rebar meets the rigorous Chinese national standard GB1499.2 and offers superior ductility and weldability. Whether you are building bridges, high-rise structures, or heavy-duty foundations, our HRB500 bars provide the confidence and performance you need.
Product Features and Technical Specifications
- High Strength Grade HRB500 – Yield strength ≥ 500 MPa, ideal for seismic-resistant and heavy-load structures.
- Deformed Surface – Ribbed pattern ensures excellent bonding with concrete, reducing slippage and improving structural integrity.
- Multiple Diameters – Available in 12mm, 16mm, and 20mm to meet diverse project requirements.
- Consistent Quality – Manufactured under strict ISO9001 quality management system, with precise chemical composition and mechanical properties.
- Good Weldability – Low carbon equivalent content allows for easy welding and bending without cracking.
- Corrosion Resistance – Optional epoxy coating or galvanized finish available upon request for harsh environments.
- Customizable Lengths – Standard lengths of 6m, 9m, 12m, or cut to your specifications.
Technical Parameters (Typical Values)
| Diameter (mm) | Cross-sectional Area (mm²) | Weight per meter (kg/m) | Yield Strength (MPa) | Tensile Strength (MPa) | Elongation (%) |
|---|---|---|---|---|---|
| 12 | 113.1 | 0.888 | ≥500 | ≥630 | ≥16 |
| 16 | 201.1 | 1.580 | ≥500 | ≥630 | ≥16 |
| 20 | 314.2 | 2.470 | ≥500 | ≥630 | ≥16 |
Advantages Over Lower-Grade Rebars
- Reduced Steel Consumption – Higher strength allows for smaller diameters or fewer bars, saving material cost and reducing dead load.
- Improved Seismic Performance – Excellent ductility and energy absorption during earthquakes, meeting stringent building codes.
- Enhanced Durability – Better resistance to fatigue and stress corrosion, extending the service life of structures.
- Easier Handling and Installation – Lighter weight per unit strength compared to lower grades, reducing labor and transportation costs.
Applications
- High-rise buildings and skyscrapers
- Bridge and highway construction
- Industrial plants and warehouses
- Dams, tunnels, and waterfront structures
- Precast concrete elements and piles
- Heavy-duty foundations and retaining walls

Frequently Asked Questions (FAQ)
-
What is the difference between HRB500 and HRB400?
HRB500 has a minimum yield strength of 500 MPa, compared to 400 MPa for HRB400. This allows for reduced steel usage and higher load-bearing capacity, making it ideal for high-stress applications. -
Can you provide a mill test certificate?
Yes, we provide a mill test certificate (MTC) for each batch, detailing chemical composition and mechanical properties as per GB1499.2. -
What lengths are available?
Standard lengths are 6m, 9m, and 12m. Custom lengths can be produced upon request with a minimum order quantity. -
Is this rebar suitable for welding?
Yes, HRB500 has good weldability due to controlled carbon equivalent (Ceq ≤ 0.55%). However, preheating may be required for thicker sections in cold weather. -
Do you offer third-party inspection?
We can arrange for inspection by SGS, BV, or other independent agencies at your cost. It is recommended to ensure quality compliance. -
What is the typical lead time?
For standard sizes and quantities, lead time is 15-20 days after order confirmation. Larger orders may require 25-30 days. -
Can the bars be supplied with a protective coating?
Yes, we offer optional epoxy coating, galvanizing, or rust-inhibiting oil as per your specifications. Please inquire for details. -
What is the minimum order quantity (MOQ)?
Our MOQ for HRB500 deformed steel bars is 25 metric tons per size, but we can accommodate smaller trial orders for new customers.
