Material Grade | Structural components, machinery | Yield Strength: Industry: 235 MPa (Q235B, ASTM A370) Base: 235 MPa (Q235B) Advanced: 355 MPa (ST52 ▲▲, ASTM A370) | Advanced grade handles extreme loads (e.g., bridges); Base cost-effective for general use | Advanced may cost 20-30% more; Base insufficient for high-stress applications |
Processing Capabilities | Custom fabrication, industrial assembly | Services: Industry: Cutting Base: Cutting/Punching Advanced: Full suite (Cutting/Bending/Welding/Decoiling ▲▲) | Advanced enables complex in-house fabrication (e.g., machinery frames); Base covers essentials | Advanced requires specialized machinery; Base may need outsourcing for bending |
Compliance Standards | International projects | Certifications: Industry: ASTM Base: ASTM/DIN/GB Advanced: ASTM/DIN/GB/JIS/AISI/BS ▲ | Advanced meets global standards (e.g., aerospace exports); Base covers major markets | Advanced incurs higher certification costs; Base may limit niche markets |
Surface Treatment | Corrosive environments | Finish: Industry: Uncoated Base: Hot-rolled Advanced: Coated (ASTM A153 zinc ▲) | Advanced prevents corrosion in offshore platforms; Base is cost-effective | Advanced coating adds 15% to cost; Base may rust without additional treatment |
Thickness Tolerance | Precision engineering | Tolerance: Industry: ±2% Base: ±1.5% Advanced: ±1% (ISO 3801 ▲) | Advanced ensures precision in aerospace parts; Base meets most industrial specs | Advanced may have longer lead times; Base insufficient for micromachining |
Application Suitability | Heavy machinery, construction | Use Case: Industry: General Base: Medium-duty (e.g., roofs) Advanced: High-strength structural ▲ (e.g., crane beams) | Advanced handles extreme loads (e.g., bridges); Base suits moderate applications | Advanced may be overkill for simple tasks; Base lacks for heavy-duty needs |
