| Environmental Factor | Impact on Traditional Metal Roofing | Our PVC Engineering Performance |
| High Salt-Spray | Rapid oxidation, edge rust, and pinhole leaks. | 100% Sea-salt resistant; zero oxidation. |
| Acidic Mineral Dust | Chemical reaction leading to coating peeling. | Chemical-proof cladding; resists pH 2-12. |
| Fertilizer Storage | Extreme corrosive off-gassing (Urea/Nitrate). | Inert polymer structure; no reaction. |
| Coastal Humidity | Accelerated electrolytic corrosion. | Non-conductive & moisture-proof material. |
| Maintenance Cost | Frequent anti-rust painting & replacement. | Maintenance-free for 15-20+ years. |
| Technical Property | Mining Grade Specification | B2B Operational Advantage |
| Corrosion Resistance | No change in H2SO4, NaOH, NaCl (24h) | Chemical-proof cladding for mining facilities |
| Salt Spray Test | Passed 2,000+ Hours (ASTM B117) | Proven Sea-salt resistant roofing |
| Tensile Strength | ≥ 25 MPa | High structural rigidity for large-span sheds |
| Flexibility | No cracking when bent (Low temperature) | Resists mechanical stress in mining sites |
| Thickness Options | 2.5mm / 3.0mm (Reinforced) | Long-term durability in high-impact zones |
| Surface Finish | Smooth, Non-porous UV Layer | Easy-to-wash mineral dust buildup |
