Welcome to Hemaokang Steel (Shandong) Co., Ltd., a reliable exporter established in 2025 with an annual export value of US$50–100 million and a team of 51–100 skilled professionals. We are proud to present our Deformed Steel Bar 12mm Diameter 6m Length ASTM A615 Grade 60 Ribbed Surface — a premium reinforcement solution designed for demanding construction projects worldwide. Our product combines superior strength with excellent bond performance, ensuring structural integrity in concrete applications. With ISO9001 certification and efficient shipping from Qingdao port, we deliver consistent quality to global markets including North America, South America, Europe, Asia, Africa, and Oceania.
This deformed steel bar is manufactured to meet the rigorous requirements of ASTM A615 Grade 60, offering a minimum yield strength of 420 MPa and a tensile strength of 620 MPa. The 12mm diameter and 6m length provide versatility for a wide range of reinforced concrete structures, from residential foundations to large-scale infrastructure. The ribbed surface pattern is specifically engineered to enhance bonding with concrete, reducing slippage and improving load transfer efficiency. Our strict quality control processes ensure dimensional accuracy, consistent mechanical properties, and defect-free surfaces.

Key Advantages and Customer Benefits
- Enhanced Bonding: The ribbed surface increases the mechanical interlock with concrete, reducing slip and improving structural performance — especially critical in seismic zones or high-load applications.
- Consistent Quality: Our ISO9001-certified production line ensures every bar meets strict dimensional and mechanical tolerances, minimizing waste and rework on site.
- Cost-Effective: By optimizing the chemical composition and rolling process, we achieve Grade 60 strength without excessive alloying, offering competitive pricing without compromising safety.
- Global Logistics: Based in Liaocheng, Shandong, we ship from Qingdao port — one of China’s busiest ports — with efficient customs clearance and reliable delivery to over 20 countries.
- Custom Options: Lengths from 3m to 12m, different bundling configurations, and special packaging (e.g., containerized or break-bulk) are available to suit your project needs.
- Technical Support: Our experienced team provides mill test certificates, third-party inspection reports, and guidance on welding, bending, and placement per ASTM standards.

Frequently Asked Questions
1. What is the difference between deformed steel bar and plain round bar?
Deformed steel bars have ribs or lugs on the surface, which significantly improve the bond with concrete. Plain round bars rely solely on friction and are more prone to slipping. For reinforced concrete structures, deformed bars like our ASTM A615 Grade 60 are the standard choice for enhanced load transfer.
2. Is this product suitable for earthquake-resistant structures?
Yes. Grade 60 deformed bars with a ribbed surface provide excellent ductility and bond strength, making them suitable for seismic applications. Our product meets the elongation and bend test requirements of ASTM A615, which are essential for energy dissipation during seismic events.
3. Can I get a mill test certificate (MTC) with each shipment?
Absolutely. We provide a mill test certificate for every batch, detailing chemical composition, mechanical properties, and dimensional compliance. Third-party inspection by SGS, BV, or other agencies is also available upon request at an additional cost.
4. What is the minimum order quantity (MOQ)?
Our standard MOQ is 25 metric tons for a single size. For smaller quantities or sample orders, please contact us to discuss options. We aim to accommodate both trial orders and large-scale projects.
5. How is the product packaged for sea freight?
Bars are bundled with steel straps in 2-ton bundles, with each bundle clearly tagged with size, grade, and heat number. Waterproof wrapping (tarpaulin or shrink wrap) is available for additional protection against moisture. We can also load directly into containers or break-bulk according to your shipping method.
6. Does the 12mm diameter bar meet the ASTM A615 tolerance requirements?
Yes. Our production process strictly controls the diameter within ±0.5mm (or tighter upon request) as per ASTM A615 Table 1 for nominal diameter 12mm. We also perform regular laser gauging and manual checks to ensure compliance.
7. Can you provide welding recommendations for this steel?
Grade 60 deformed bars are weldable using low-hydrogen electrodes and preheating as per AWS D1.4. We can supply a general welding guideline based on the carbon equivalent (CE) of our steel. For specific projects, we recommend consulting a structural engineer.
8. What payment terms do you accept?
We accept T/T (30% deposit, 70% against copy of shipping documents) and irrevocable L/C at sight. For long-term partners, other terms may be negotiable. All transactions are handled with full transparency and documentation.
