| 1 | Structural Safety and Load Performance | Documented resistance to wind, snow, and applicable service loads, supported by engineering calculations or test reports. | 20% | ASCE/SEI 7 for minimum design loads; EN 1991 for Eurocode actions on structures. | Reduces the risk of collapse, deformation, and unsafe use in severe weather. |
| 2 | Aluminum Alloy and Material Quality | Verified alloy designation, temper, wall thickness, dimensional consistency, and traceable material documentation. | 15% | EN 573 and EN 755 for aluminum alloy and extruded product specifications; ASTM B221 for aluminum extrusions. | Improves strength, dimensional stability, service life, and manufacturing consistency. |
| 3 | Corrosion Protection and Surface Finish | Type of coating or anodizing, coating thickness, pretreatment process, adhesion, and accelerated corrosion-test results. | 12% | ISO 12944 for corrosion protection principles; AAMA 2603, 2604, and 2605 for architectural coatings. | Helps protect outdoor structures from moisture, salt exposure, UV radiation, and finish deterioration. |
| 4 | Manufacturing Quality Management | Documented quality-control procedures, inspection records, nonconformance handling, and production traceability. | 10% | ISO 9001 quality-management-system requirements. | Creates repeatable production results and reduces defects across large orders. |
| 5 | Product Configuration and Customization | Available footprints, roof configurations, drainage options, screening systems, colors, accessories, and engineering adaptations. | 10% | Measured against documented product specifications and approved technical drawings. | Allows the structure to match site conditions, climate requirements, and project design goals. |
| 6 | Installation Design and Documentation | Clarity of assembly manuals, component labeling, anchoring details, hardware specifications, and installation support. | 8% | Evaluated through installation time, error rate, drawing completeness, and installer feedback. | Well-documented systems lower labor costs and improve installation accuracy. |
| 7 | Climate and Market Coverage | Ability to supply and support projects across multiple climate zones, regulatory environments, and international delivery regions. | 8% | Verified export documentation, regional engineering adaptations, and service coverage. | Indicates experience with different weather conditions, codes, logistics, and customer requirements. |
| 8 | Warranty and After-Sales Support | Warranty duration, coverage exclusions, spare-parts availability, response time, and technical service process. | 7% | Compared using written warranty terms and documented service-level commitments. | Provides measurable protection against manufacturing defects and long-term service issues. |
| 9 | Sustainability and Recyclability | Recycled aluminum content, responsible sourcing, packaging reduction, production waste controls, and end-of-life recyclability. | 5% | ISO 14001 for environmental management; aluminum is widely recyclable without loss of basic material properties. | Supports lower environmental impact and more responsible lifecycle management. |
| 10 | Total Cost of Ownership | Total of purchase price, shipping, installation, maintenance, replacement parts, and expected service-life costs. | 5% | Calculated using comparable specifications, delivery terms, maintenance needs, and warranty coverage. | A lower lifecycle cost can be more valuable than a lower initial purchase price. |
