Hemaokang Steel (Shandong) Co., Ltd. proudly presents our premium Steel Rebar 8mm Diameter HRB400 Grade Standard Length 9m. As a manufacturer with an annual export value of US$50–100 million and ISO9001 certification, we ensure every rebar meets rigorous international standards. These rebars are designed to provide exceptional tensile strength and ductility for reinforced concrete structures, making them an ideal choice for construction projects worldwide. Whether you're building bridges, highways, or multi-story buildings, our HRB400 grade rebar delivers reliability and performance you can trust.
Our 8mm diameter deformed steel bars are produced from high-quality carbon steel billets, hot-rolled and subjected to controlled cooling to achieve the desired mechanical properties. The ribbed surface pattern ensures optimal bond with concrete, reducing slippage and increasing structural integrity. Each bar is cut to a standard length of 9 meters, offering convenience and cost-efficiency for on-site handling and installation.
Key Features & Technical Specifications
- High Yield Strength: Minimum yield strength of 400 MPa ensures robust load-bearing capacity.
- Excellent Weldability: Low carbon equivalent (CE) allows easy welding without preheating.
- Consistent Dimensions: Precise diameter control (tolerance ±0.4mm) guarantees uniformity.
- Corrosion Resistance: Optional epoxy coating or galvanizing available upon request for harsh environments.
- Standardized Length: 9m length reduces waste and simplifies logistics.

Our rebar is manufactured in strict compliance with Chinese national standard GB/T 1499.2-2018 and is fully traceable from raw material to finished product. Each bundle is clearly labeled with heat number, grade, and length for easy identification on site. The 8mm diameter is particularly popular for light to medium-duty applications such as slabs, beams, columns, and foundations, where a balanced combination of strength and weight is required.
Customer Benefits
- Cost-Effective: Lower weight per meter compared to larger diameters reduces material cost without compromising structural integrity.
- Easy Handling: Light enough for manual placement yet strong enough for demanding loads.
- Global Compatibility: HRB400 grade aligns with many international standards (e.g., ASTM A615 Grade 60, BS 4449 Grade 460B).
- Reliable Supply: Our 51-100 workforce and robust production capacity ensure timely delivery for large projects.

Frequently Asked Questions
Q1: What is the difference between HRB400 and HRB500 rebar?
A: HRB500 has a higher yield strength (500 MPa) but is more brittle. HRB400 offers a good balance of strength and ductility for most reinforced concrete applications.
Q2: Can the rebar be cut to custom lengths?
A: Yes, we offer customized lengths upon request. Typical range is 6m to 12m, but other lengths can be arranged.
Q3: Is this rebar suitable for seismic zones?
A: HRB400 grade is commonly used in seismic designs due to its adequate elongation and bendability. For special seismic requirements, HRB400E (seismic grade) is available.
Q4: What packing options do you provide?
A: Standard packing is in bundles with steel strips (2-3 tons per bundle). We also offer waterproof wrapping or container loading as per your request.
Q5: Do you provide a mill test certificate?
A: Absolutely. Each shipment includes a mill test certificate showing chemical composition and mechanical properties.
Q6: How long does delivery typically take?
A: For standard products, production takes 10-15 days after order confirmation. Shipping time depends on destination (e.g., 20-30 days to North America by sea).
Q7: What is the minimum order quantity?
A: The standard MOQ is 25 metric tons (approximately 56 bundles). Smaller trial orders may be considered.
Q8: Can you provide samples before bulk order?
A: Yes, free samples (up to 1 meter length) are available. Buyer covers shipping cost.
