In the past, metal roofing options were limited to choices like corrugated metal, which has improved over time but still offers limited aesthetic appeal, or costly copper cladding. However, a modern innovation-stone-coated metal roofing-now provides a durable and visually appealing alternative. Combining the strength of steel with the look of tile, shake, shingle, or other styles, it offers a long-lasting roofing solution without compromising on design. No matter the architectural style of your home or property, there's a stone-coated metal roofing option to match your needs.

Alu-Zinc electroplated steel sheets, also known as Galvalume steel, are the foundation material for stone-coated roofing tiles, offering exceptional strength, corrosion resistance, and longevity. These sheets are coated with a precise blend of aluminum (55%), zinc (43.4%), and silicon (1.6%), providing superior protection against rust, heat, and extreme weather conditions.
Alu-Zinc steel is manufactured using a continuous hot-dip process, where a steel core is electroplated with a thin but highly durable layer of aluminum-zinc alloy. This alloy enhances the sheet's resistance to oxidation, moisture, and environmental pollutants, making it ideal for roofing applications.
Superior Corrosion Resistance - Lasts 3-6 times longer than galvanized steel due to the aluminum-zinc barrier.
High Durability - Withstands extreme weather, including heavy rain, snow, and salt-laden coastal air.
Lightweight Yet Strong - Provides excellent strength-to-weight ratio, reducing structural load.
Heat & UV Reflection - Reflects solar radiation, reducing heat absorption and improving energy efficiency.
Excellent Adhesion for Stone Coating - Ensures a strong bond between the steel surface and stone chips for long-term durability.

Stone chips play a crucial role in the performance and aesthetics of stone-coated roofing tiles, offering both durability and weather resistance. These high-quality natural mineral granules are carefully selected, processed, and coated to enhance the strength and longevity of roofing materials.
The stone chips used in roofing tiles are primarily derived from natural basalt or granite, known for their high density, hardness, and weather resistance. These minerals are crushed into fine granules and coated with ceramic pigments to achieve various colors and enhanced UV resistance.
Aesthetic Appeal - Available in a variety of colors to match architectural styles.
Weather Protection - Shields the steel base from environmental elements like UV rays, rain, and hail.
Noise Reduction - Dampens rain and impact noise compared to metal roofs.
Anti-Corrosion - Acts as a protective layer, preventing direct exposure of the steel surface to moisture and air.
Thermal Insulation - Enhances energy efficiency by reflecting heat and reducing indoor temperatures.
Stone-coated roof tiles combine durability, aesthetics, and weather resistance, making them an excellent choice for both residential and commercial roofing projects. Stone-coated roof tiles provide the perfect balance of strength, beauty, and efficiency, making them one of the best roofing materials available. They ensure long-term protection, enhance property value, and offer superior performance in all weather conditions.
