Colored Stone Metal Tiles are a new type of roofing material made from an aluminum-zinc-coated steel plate as the base material, with a surface covered by colored sintered sand grains and an acrylic resin protective layer. They combine the strength of metal with the aesthetic appeal of natural stone, making them one of the mainstream high-end roofing solutions internationally.
I. Basic Composition
1. Base Material: Aluminum-zinc-coated steel plate composed of 55% aluminum, 43.4% zinc, and 1.6% silicon, with a corrosion resistance lifespan 2–6 times that of ordinary galvanized steel plates.
2. Anti-fingerprint Coating: Transparent or light green, protecting the aluminum-zinc layer and enhancing adhesion to the colored sand.
3. Colored Stone Grains: Basalt particles colored through high-temperature sintering, available in over ten colors, offering UV resistance and reducing rain noise.
4. Acrylic Resin: Firmly bonds the colored sand to the steel plate and forms a surface sealing layer, preventing water leakage and aging.
II. Common Tile Types
Seven-wave tile (arc tile), eight-wave tile (Milan tile), beveled-edge tile (diamond tile), wood grain tile, grid tile, small Roman, large Roman, etc.
III. Core Performance
? Ultra-lightweight: 2.8 kg per tile, ≈5.8 kg/㎡, reducing structural load.
? Ultra-long lifespan: 30–50 years, even up to 70 years.
? Weather resistance: Resistant to extreme cold, heat, hail, acid rain, and salt spray.
? Safety: Non-combustible, withstands typhoons up to level 12, earthquake-resistant, and anti-slip.
? Easy installation: Large single-piece area, cuttable and bendable, dry-lock connection + horizontal nailing, can cover old roofs without removal, short construction period, and labor-saving.
IV. Application Scope
Suitable for various sloped roofs with gradients of 12°–90°: villas, mid-to-high-end residences, shopping malls, libraries, hospitals, schools, government office buildings, landscape houses, etc.; particularly suitable for "flat-to-slope" conversions, old roof renovations, wood structures, steel structures, and concrete structures.
V. Economic and Environmental Advantages
? Directly covers old tiles, minimizing waste disposal costs.
? Metal parts are recyclable, production process is pollution-free, compliant with green building material policies.
Single tile dimensions: 1340 mm × 420 mm, thicknesses: 0.3mm, 0.35mm, 0.4mm, 0.45mm.
Due to their comprehensive advantages of being "lightweight, fast, beautiful, and durable," Colored Stone Metal Tiles have become the preferred material to replace traditional roofing materials such as clay tiles, cement tiles, color steel plates, and fiberglass asphalt tiles.
