Ridge Tiles | Villa rooftops, gable ends | Resin-Steel Composite (ASTM A370 tensile strength: 450 MPa▲) + Stone Coating (ISO 12540 weather resistance: 1000+ hours salt spray test) | ▲ Lightweight (30% lighter than clay) + Aesthetic versatility (stone texture mimics natural materials) | Higher cost vs traditional clay tiles + Requires专业安装 (specialized installation tools) |
Bent Tiles | Curved roof structures (e.g., barrel roofs) | Non-slip Texture (ASTM C1028: Coefficient of Friction ≥0.7▲) + Flexibility (bend radius: 1.2m without cracking) | ▲ Easy installation (pre-bent design) + Impact resistance (ASTM D2794: 150 J impact energy absorption) | Limited color options + May warp in extreme humidity (>90%) |
Stone-Coated Sheets | Commercial/Residential roofing | UV Resistance (ASTM G154: ΔYI < 3 after 2000hrs▲) + Fire Rating (Class B per ASTM E84) | ▲ Low maintenance (self-cleaning surface) + Energy efficiency (reflectivity: 0.25▲) | Prone to scratches in high-abrasion areas + Heavier than PVC alternatives |
Resin/Steel Composites | High-stress roof areas (e.g., eaves) | Corrosion Resistance (ASTM B117: 1000+ hours salt spray▲) + Load Capacity (2.5 kN/m²▲) | ▲ Long lifespan (25+ years warranty) + Recyclable material (ISO 14021 certified) | Higher upfront cost + Requires专业 storage (avoid prolonged UV exposure) |
Non-Slip Surface Texture | Wet/slippery roof environments | Grip Enhancement (reduces slips by 40%▲ per OSHA 1926.501) + Ergonomic Handling (reduces installer fatigue) | ▲ Safety compliance (meets ANSI Z359.1) + Durability (retains texture after 5000 abrasion cycles) | Adds 15% weight vs smooth surfaces + Cleaning requires mild detergents |
Villa Roofing Systems | Luxury residential projects | Aesthetic Integration (matches villa architecture) + Customizable Curvature (radius: 0.8–2.5m▲) | ▲ Market differentiation (premium look) + Modular design (reduces installation time by 30%) | Higher labor costs + Limited availability in remote regions |
