Standard Deformed Rebar | Residential, light commercial structures | HRB335 grade (335 MPa), 6–25mm diameters, ribbed surface (ASTM A615), CE certified | Cost-effective, widely available, basic compliance standards | Lower strength (335 MPa vs HRB400’s 400 MPa), limited diameter range, less durable in harsh conditions |
HRB400 Grade Rebar (Our Base) | Medium/heavy construction (e.g., bridges) | HRB400 grade (400 MPa▲), 6–40mm diameters (ISO 1006), ribbed surface (25% better adhesion▲), CE+ASTM | ▲ 25% stronger than HRB335, versatile diameters, 1% tolerance (precision▲) | Moderate cost, requires skilled installation for optimal performance |
HRB500 Grade Rebar (Our Advanced) | High-stress structures (skyscrapers) | HRB500 grade (500 MPa▲▲), 12–40mm diameters, dual coatings (ASTM A767), CE+EN 10080 | ▲▲ 43% stronger than HRB335, corrosion-resistant coating (ASTM A767), premium durability | Higher cost, specialized manufacturing, limited supplier availability |
Smooth Steel Rebar (Industry) | Temporary/low-load structures | Smooth surface, HRB300 grade (300 MPa), 6–16mm diameters, basic compliance | Cheapest option, easy to handle | Poor adhesion to concrete (50% weaker bond), unsuitable for permanent structures |
Corrosion-Resistant Coated Rebar | Marine/humid environments | Zinc-coated (ASTM A767), HRB400 grade, 8–25mm diameters, EN 10249 certification | Extended lifespan in corrosive environments (▲ 3x longer than uncoated) | Higher cost, coating may chip during installation, requires protective handling |
Precision-Tolerance Rebar | High-precision engineering projects | ±0.5mm tolerance (ISO 1006▲), 10–32mm diameters, CE+ASTM A615 | ▲ Double the accuracy of standard rebar, reduces structural errors | Limited to smaller diameters, specialized production increases lead time |
