Durability: stone coated roofing tiles combine the benefits of aluminum and zinc materials. The Galvanized steel sheet has passed 2,000 hours of salt spray testing (ASTM B117), showcasing exceptional durability.
Lifespan: Stone coated roofing sheets offer a 50-year warranty, reflecting not only laboratory test results but also excellent performance in real-world installations globally. Stone Coated roofing is an ideal choice for long-term investment.
Fire Resistance: Stone coated roofing sheets have passed fire resistance tests, earning a UL 790 Class A fire rating. This demonstrates that stone-coated roofing offers excellent fire resistance, will not contribute to combustion, and does not release toxic gases.
Wind Resistance: Stone coated roofing sheets have undergone wind resistance testing and can withstand strong winds of up to 120 mph (approximately 193 km/h). This performance meets the building code requirements for most regions.
Aesthetic Variety: Stone-coated roofing sheets offer a wide range of colors and styles, such as wood grain, square, and curved designs. They have also performed exceptionally well in laboratory accelerated aging tests (3,000-5,000 hours of UV exposure and water spray) and outdoor natural exposure tests.
Ease of Installation: Stone-coated roofing sheets are lightweight (6-7 kg per square meter) and have fixed dimensions (typically 1340mm x 420mm), making them easy to install without the need for complex tools or techniques. This simplifies the installation process, saving both time and costs.
