Hemaokang Steel (Shandong) Co., Ltd. is proud to offer the HRB400 12mm Deformed Steel Bar – a premium concrete reinforcement product manufactured in strict compliance with ASTM A615 Grade 60 standards. With an annual export value exceeding US$50 million and a dedicated team of 51–100 skilled professionals, we ensure consistent quality and reliable supply. Our rebar is designed to meet the rigorous demands of modern construction, providing superior bond strength and structural integrity. Whether you are building bridges, highways, or high-rise buildings, this deformed steel bar delivers the performance you can trust.
Our 12mm deformed bar features a unique ribbed pattern that enhances mechanical anchorage within concrete, significantly improving load transfer and crack resistance. Manufactured from high-quality carbon steel and subjected to strict quality control, each bar meets the stringent requirements of ASTM A615 Grade 60 – the most widely accepted specification for concrete reinforcement in North America and many other regions. With a tensile strength of 620 MPa (minimum) and a yield strength of 420 MPa (minimum), this product ensures long-lasting durability and safety.
Key Features & Technical Specifications:
- High Strength: Yield strength ≥ 420 MPa, tensile strength ≥ 620 MPa, ensuring excellent load-bearing capacity.
- Excellent Ductility: Elongation ≥ 9% (typical), providing flexibility to absorb seismic forces.
- Superior Bond with Concrete: Deformed ribs increase surface area and mechanical interlock, reducing slippage.
- Consistent Dimensions: Diameter tolerance: ±0.5 mm; length tolerance: +50 mm / -0 mm.
- Corrosion Resistance Options: Available with epoxy coating or black finish (upon request).
- Bendability: Can be cold bent to 180° without cracking, compliant with ASTM A615 requirements.

Frequently Asked Questions (FAQ)
- Q: What is the difference between HRB400 and ASTM A615 Grade 60? A: HRB400 is a Chinese standard (GB/T 1499.2) with similar yield strength (400 MPa) to Grade 60 (420 MPa). Our product is manufactured to meet both standards, with a minimum yield strength of 420 MPa to comply with ASTM A615 Grade 60.
- Q: Can this rebar be used in seismic zones? A: Yes. The rebar offers excellent ductility (elongation ≥9%) and can be cold bent 180°, making it suitable for seismic applications. However, always consult local building codes for specific requirements.
- Q: What lengths are available? A: Standard lengths are 6m, 9m, and 12m. Custom lengths can be produced upon request with a minimum order quantity.
- Q: Do you offer third-party inspection? A: Yes. We welcome inspections by SGS, Bureau Veritas, or any other accredited third-party agency. Our products are fully traceable and test certificates are provided.
- Q: What is the typical lead time for a 20-foot container? A: For standard specifications, the lead time is 15–20 days after confirmation of order and payment. Custom orders may require additional time.
- Q: How is the rebar packed for shipping? A: Each bundle is tightly strapped with steel strips and labeled with grade, diameter, and heat number. Waterproof wrapping is optional for sea freight.
- Q: Is the rebar weldable? A: Yes, ASTM A615 Grade 60 rebar is weldable using appropriate preheating and welding procedures. We recommend following AWS D1.4 guidelines for structural welding.
- Q: What payment terms do you accept? A: We accept T/T (30% deposit, 70% balance before shipment) and L/C at sight. Other terms may be negotiated for long-term partners.
