Stone Finished Metal Roofing Shingles

Hurricane-Rated Roof Shingles

Hurricane-rated roof shingles feature a reinforced interlocking system with dual-clip technology, achieving wind uplift resistance of 110 mph (ASTM D3161 Class F) and passing TAS-117 impact tests. The 0.48mm AZ150 steel core is coated with 180g/㎡ Alu-Zn alloy (55% aluminum, 43.4% zinc), enabling 1,500-hour salt spray resistance—critical for Caribbean islands and Southeast Asian typhoon corridors. During 2024 Cyclone Mawar, these shingles maintained zero detachment across 200+ structures in Okinawa. The stone layer uses 3-5mm basalt granules sintered at 1,200°C, reducing rain noise to 28 dB while reflecting 85% solar radiation to lower attic temperatures.

Installation incorporates hurricane straps and seamless edge sealing, allowing direct overlay on damaged roofs without structural reinforcement. Our factory holds Miami-Dade County NOA certification, with ISO 9001 quality control ensuring 99.8% dimensional accuracy. Custom lengths (up to 2,500mm) accommodate dome-shaped resorts in Maldives and Bahamas. Case study: A Philippines coastal hotel reduced post-typhoon repair costs by 70% after switching to this system.
