Metal Roofing Shingles With Stone Coating

Coastal Corrosion-Proof Tiles

Coastal corrosion-proof tiles employ AZM200 alloy coating (150g/m² Al-Mg-Si) and 316L stainless steel fasteners, passing 2,000-hour salt spray tests (ISO 9227) – essential for offshore rigs and tropical islands. The cationic electro-coating (ED) layer provides sacrificial anode protection, halting corrosion at scratches. Granules infused with TiO₂ break down salt deposits, maintaining Solar Reflectance Index (SRI) ≥80 after decades. Wind-driven rain defense exceeds 1,000mm/h (ASTM E331) due to triple-sealed seams.

Installation mandates copper-free aluminum flashings to prevent galvanic corrosion. Our factory’s coastal series includes zinc anodes for critical joints, backed by a 50-year perforation warranty. Projects: Bahamas resorts with zero rust after 15 years in Category 5 storm zones.
