Material Composition | High-stress industrial/commercial roofs | Industry: Galvanized Steel (ASTM A153) Base: Aluminum 6061 (ASTM B211) ▲ Advanced: 5052-H32 Aluminum (ASTM B209) ▲▲ (enhanced tensile strength: 276 MPa) | Lighter weight, corrosion resistance (Base: 0.8 mm thickness; Advanced: 1.2 mm) | Advanced alloys increase cost by ~20% compared to Base tier. |
Surface Coating | Aesthetic customization in residential | Industry: Paint (ASTM D3359) Base: Stone Coated (ASTM D4294) ▲ (resists UV for 10+ years) Advanced: PVDF Coating (ASTM D3359, 20+ years fade resistance) ▲▲ | Enhanced color durability, UV resistance (Advanced: 98% color retention vs. Industry’s 75%) | Advanced coatings require specialized installation. |
Structural Design | Roofs with heavy rainfall/wind exposure | Industry: Flat Profile (ISO 10360) Base: Ribbed Profile (ISO 10360, 15° angle) ▲ Advanced: Reinforced Ribbed (ISO 10360, 22° angle for 120km/h wind) ▲▲ | Improved drainage (Base: 25% faster runoff; Advanced: 40% faster) and wind resistance | Advanced designs may require stronger roof framing. |
Weather Resistance | Extreme weather regions (hail, hurricanes) | Industry: Wind Resistance (ASTM E330, 90km/h) Base: 120km/h ▲ Advanced: 150km/h ▲▲ (Class A Fire Rating: ASTM E108 across all tiers) | Advanced tiers withstand Category 3 hurricane-force winds | Higher-tier materials add ~15% roof weight. |
Noise Reduction | Urban offices/hospitals | Industry: 45 dBA (ISO 140-3) Base: 38 dBA ▲ (quieter than a whisper) Advanced: 32 dBA ▲▲ (quieter than rainfall) | Advanced reduces noise pollution by 29% vs. Industry standards | Thicker materials may complicate retrofit installations. |
Customization | Architectural projects | Industry: 10+ colors (ASTM E1082) Base: 20+ colors ▲ Advanced: 30+ colors + custom patterns ▲▲ (ISO 3834-2 certified) | Advanced offers bespoke designs for unique architectural styles | Custom orders may add 2–3 weeks to delivery timelines. |
