Material Grade | Construction projects requiring varying strength levels | HRB335 (▲) 335 MPa yield strength (GB/T 1499.2), HRB400 (▲▲) 400 MPa, HRB500 (▲▲▲) 500 MPa (ASTM A615) | ▲▲▲ HRB500: Superior load-bearing for heavy infrastructure ▲ HRB335: Cost-effective for general building | Higher grades (▲▲▲) may increase material costs by 15–20% compared to base tiers |
Length Options | Site-specific requirements (e.g., bridges vs residential) | 6m and 12m lengths (customizable via cutting service) | Flexible for diverse project needs (e.g., 12m for bridges, 6m for residential) | Longer bars (12m) require specialized transport logistics for delivery |
Processing Services | Custom fabrication needs (e.g., curved structures) | Decoiling, welding, bending, cutting, punching (ISO 9001 certified) | Reduces dependency on third-party contractors for complex designs | Custom processing may extend lead times by 2–3 business days |
Compliance Standards | International projects (e.g., EU/US/Asia) | Meets ASTM A615, GB/T 1499.2, DIN 488, EN 10080, JIS G3112, and AISI standards | Wider market acceptance across global construction markets | Compliance with multiple standards may limit material customization options |
Dimensional Tolerance | Precision engineering (e.g., machinery components) | ±1% diameter tolerance (ISO 1940) | Ensures seamless integration in high-precision structural systems | Tighter tolerances may increase production costs by ~10% |
Strength Tier | Heavy-duty infrastructure (e.g., skyscrapers, bridges) | HRB500 (▲▲▲) ▲▲▲ 500 MPa > HRB400 (▲▲) ▲▲ 400 MPa > HRB335 (▲) ▲ 335 MPa (ASTM A615) | ▲▲▲ HRB500: Ideal for high-stress applications requiring minimal deflection | Higher-tier grades (▲▲▲) may sacrifice ductility compared to lower-tier options |
