Material Grade | Structural frameworks, bridges | Industry Standard: SS345 (345 MPa) Our Base: SS400 (400 MPa) ▲ Our Advanced: SS540 (540 MPa) ▲▲ | ▲ Base: 15% stronger than industry standard. ▲▲ Advanced: 57% stronger than SS345. | Higher grades (e.g., SS540) may incur 20-30% cost premium. |
Manufacturing Standard | Global construction projects | Industry Standard: Single standard (e.g., ASTM A6) Our Base/Advanced: Complies with JIS G 3192, GB/T 706, ASTM A6/A6M, BS 4 | Ensures compatibility across markets (e.g., Japan, China, US, UK). | Compliance with multiple standards may require additional certification costs. |
Manufacturing Technique | Mass production of beams/columns | Industry Standard: Cold-rolled (surface finish: Ra 1.6 μm) Our Base/Advanced: Hot-rolled (Ra 5-10 μm) ▲ | ▲ Hot-rolling reduces production costs by 15-20% vs cold-rolled. | Rougher surface may require post-processing for aesthetic applications. |
Cross-Section Type | Symmetrical load distribution | Industry Standard: Unequal legs (e.g., 50x30x5mm) Our Base/Advanced: Equal legs (e.g., 50x50x6mm ISO 520) ▲ | ▲ Equal legs optimize multi-directional support in frameworks. | Less suited for unidirectional load scenarios (e.g., cantilever beams). |
Customization Solutions | Tailored construction projects | Industry Standard: Limited to cutting (tolerance ±3mm) Our Base: Cutting ±1mm (ISO 14363) ▲ Advanced: Cutting + bending/welding ▲▲ | ▲ Base: Precision cuts reduce waste. ▲▲ Advanced: Full customization for complex designs. | Custom welding may add 2-3 days to lead time. |
Quality Assurance | Critical infrastructure (hospitals, skyscrapers) | Industry Standard: Basic mill certification Our Base: ISO 3834 welding (EN 10204 3.1) ▲ Advanced: Third-party NDT testing ▲▲ | ▲ Base: Ensures weld integrity. ▲▲ Advanced: Zero-defect assurance for safety-critical uses. | Advanced certifications increase unit cost by 10-15%. |
