As a leading manufacturer from Hemaokang Steel (Shandong) Co., Ltd., we take pride in offering Reinforced Steel Deformed Bars in diameters of 12mm, 16mm, and 20mm, meeting the rigorous standards of ASTM A615 Gr60 and HRB400. Established in 2025, our company has quickly grown to achieve an annual export value of US$50 million to US$100 million, serving markets across North America, South America, Eastern Europe, Southeast Asia, Africa, and more. Our hot rolled ribbed rebar is specifically designed for concrete construction, providing superior bonding strength and structural integrity. With ISO9001 certification and a dedicated team of 51-100 employees, we ensure every bar meets the highest quality benchmarks.
Our deformed steel bars are produced through a state-of-the-art hot rolling process, resulting in a ribbed surface that enhances mechanical anchorage within concrete. Available in the most common diameters (12mm, 16mm, 20mm), these bars are ideal for reinforcing slabs, beams, columns, foundations, and other concrete structures. The combination of ASTM A615 Gr60 and HRB400 specifications guarantees a minimum yield strength of 60,000 psi (420 MPa) and excellent ductility, making them suitable for both residential and commercial projects.

Frequently Asked Questions
-
Q: What is the difference between ASTM A615 Gr60 and HRB400?
A: ASTM A615 Gr60 is a US standard for deformed steel bars with a minimum yield strength of 60,000 psi, while HRB400 is a Chinese standard (GB/T 1499.2) with a similar yield strength of 400 MPa. Our bars are manufactured to meet both specifications, ensuring compatibility with international projects. -
Q: Can you supply bars in lengths other than standard 12m?
A: Yes, we offer customizable lengths from 6m to 12m, or as per your specific requirements. Please contact us with your project details. -
Q: What is the minimum quantity for an order?
A: We typically require a minimum order of 20 metric tons per size, but smaller quantities may be accommodated for sample orders or repeat customers. Please inquire. -
Q: Do you provide mill test certificates?
A: Yes, each shipment comes with a mill test certificate (MTC) that documents the chemical composition and mechanical properties, compliant with ASTM A615 and HRB400 standards. -
Q: How do you package the bars to prevent damage during shipping?
A: Bars are securely bundled with steel strips and can be wrapped in waterproof material if needed. We also offer container loading or break-bulk shipping options. -
Q: Are these bars suitable for seismic zones?
A: Yes, the Gr60 grade provides good ductility and elongation (min 9%), making them suitable for earthquake-resistant structures in many seismic design categories. However, we recommend consulting your structural engineer for specific requirements. -
Q: What is the typical lead time for production?
A: For standard sizes and lengths, lead time is 15-20 days after order confirmation. For custom specifications, please allow 25-30 days. -
Q: Can you arrange third-party inspection?
A: Absolutely. We welcome inspection by SGS, Bureau Veritas, or any accredited third-party agency at your cost. We can also provide samples for testing before mass production.
