Colored Stone Metal Tiles are a new type of roofing material that combines "metal strength" with "natural colored stone texture," rapidly gaining popularity in high-end buildings both internationally and domestically in recent years.

I. Structure and Process 

1. Base Material: 0.4-0.6 mm aluminum-zinc (or aluminum-zinc-magnesium) coated steel plate, containing 55% aluminum, 43.4% zinc, and 1.6% silicon, with corrosion resistance 2-6 times that of ordinary galvanized steel. 

2. Adhesive Layer: Acrylic resin ensures a strong bond between the steel plate and colored sand. 

3. Colored Sand Layer: High-temperature sintered natural basalt particles, with a particle size of 0.8-1.2 mm, available in 10-15 solid or gradient colors, fade-resistant and UV-resistant. 

4. Surface Protection: Transparent weather-resistant acrylic resin topcoat further enhances weather resistance, anti-fouling, and noise reduction properties.

II. Main Tile Types 

Seven-wave tile (arc tile), eight-wave tile (Milan tile), beveled tile (diamond tile), wood grain tile, grid tile, small Roman, large Roman, etc., suitable for various architectural styles such as European, Chinese, and modern.

III. Core Advantages 

? Lightweight and High Strength: 5-8 kg/m2, only 1/6 the weight of cement tiles, reducing structural load and transportation costs. 

? Ultra-Long Lifespan: 30-50 years. 

? All-Weather Protection: Class A non-combustible, resistant to 15-level typhoons, hail, and heavy rain.

? Easy Installation: Large single-piece area (approx. 1340 mm × 420 mm), dry horizontal nailing + self-locking buckle, tripling installation efficiency, and can be directly overlaid on old roofs for renovation. 

? Eco-Friendly and Noise-Reducing: Both base material and colored sand are recyclable; surface colored sand reduces rain noise by about 30%, making heavy rain days quieter.

IV. Applicable Scenarios 

? New Construction: Wood, steel, and concrete sloped roofs (slope 12°-90°) for villas, townhouses, shopping malls, schools, hospitals, museums, etc. 

? Renovation: Flat-to-slope conversion, old roof renovation, can be directly overlaid without removing original tiles, reducing waste disposal costs.

V. Economic Reference 

? Long-Term Value: Extremely low maintenance costs over a 50-year lifecycle, with overall cost lower than traditional tiles requiring multiple renovations.

With comprehensive advantages in lightweight, durability, aesthetics, and eco-friendliness, Colored Stone Metal Tiles are becoming the preferred material for modern sloped roofs in "flat-to-slope conversion, renovation, and new construction."
