HRB400 Deformed Steel Rebar, also known internationally as ribbed steel bar, deformed reinforcing bar, or TMT bar, is a hot-rolled steel bar widely used in reinforced concrete structures. The HRB400 grade (High strength, Ribbed, Hot-Rolled) is equivalent to ASTM Grade 60 and BS4449 B500B standards. With its ribbed surface, the bar forms a strong bond with concrete, making it ideal for high-load-bearing structural elements such as columns, beams, foundations, bridges, and tunnels. Yoshine’s HRB400 rebars are manufactured using low-alloy Q345B steel, processed under strict ISO 9001 quality control, and are fully compliant with GB1499.2, ASTM A615, and BS4449 standards.
Diameter (mm) | Length (m) | Typical Application |
Φ10 | 6 / 9 / 12 | Slabs, light beams |
Φ12 | 6 / 9 / 12 | Walls, beams |
Φ16 | 6 / 9 / 12 | Columns, footings |
Φ20 | 6 / 9 / 12 | Pillars, bridges |
Φ25-32 | 6 / 9 / 12 | Heavy-duty foundations |
• Hot-rolled low-alloy steel for strength and ductility.
• Ribbed surface improves grip with concrete structures.
• High yield strength and stable elongation performance.
• Available in a variety of standard and custom sizes.
• Complies with GB1499.2, ASTM A615, BS4449, and ISO 9001.
Yoshine manufactures rebar under a certified ISO 9001 quality management system, ensuring every batch meets strict mechanical and dimensional standards. We conduct comprehensive inspections, tensile and yield testing, and material traceability throughout production. Our rebars comply with international standards such as GB1499.2, ASTM A615/A706, and BS4449, and come with mill test certificates and inspection reports upon request. This guarantees quality, transparency, and full suitability for export and use in reinforced concrete structures around the world.
✅ Superior Strength & Bonding
HRB400 rebars offer high tensile and yield strength while maintaining excellent ductility. Its ribbed surface creates a strong mechanical bond with concrete, preventing slippage under load and resisting cracking in structural components.
✅ Reliable for Heavy-Duty Applications
Whether in bridge decks, multi-storey buildings, or earthquake zones, HRB400 provides the stability and performance needed to ensure safety. It’s the ideal choice for civil and infrastructure projects requiring long-term durability.
✅ Precision Manufacturing
Yoshine produces HRB400 rebars using advanced hot-rolling lines and precision cutting. This ensures uniform diameter, consistent rib patterns, and excellent weldability for construction crews.
✅ Cost-Effective & Versatile
With high strength-to-weight ratio and easy availability in standard lengths, HRB400 is a go-to solution for contractors looking to reduce costs without compromising structural performance.
✅ Certified for Global Markets
HRB400 steel bars from Yoshine conform to international quality benchmarks including ISO 9001, BS4449 B500B, and ASTM A615 Grade 60. This makes them suitable for export and approved usage in global infrastructure and building projects.
At Yoshine, we offer full-service rebar customization tailored to your project needs. We can process steel rebar by cutting, bending, straightening, threading, and prefabricating based on your construction schedule. Our experienced rebar detailing team can work directly from your bending schedules or structural drawings to calculate exact quantities, shapes, and lengths of required rebar. This helps reduce on-site labor, optimize materials, and minimize waste. Whether you need bundled rebar sets or fully labeled and shaped reinforcement ready for installation, Yoshine provides professional rebar estimation, detailing, and prefabrication services for efficient and precise construction.
