Core technical specification: The "seven-layer structure" of the colored stone tiles
1. Anti-fingerprint Coating (Anti-fingerprint Film): Located at the bottom layer, it prevents fingerprints from being left during construction, which causes oxidation, and enhances the anti-corrosion performance of the steel plate.
2. Alu-zinc Steel Base (Aluminum-Zinc Steel Substrate): The core layer. Compared to ordinary galvanized steel plates, the aluminum-zinc alloy (typically 55% aluminum, 43.4% zinc, 1.6% silicon) has 3-6 times stronger corrosion resistance.
3. Acrylic Base Coat (Acrylic Primer): The bonding layer. It ensures that the colored stone chips can firmly adhere to the steel plate and prevent peeling.
4. Natural Stone Chips (Colored Stone Granules): The core selling point. Using basalt (Basalt) particles, they are colored through a high-temperature sintering (Sintering) process to ensure UV resistance and 50-year color retention.
5. Acrylic Glaze (Acrylic Top Coat): The top protective layer. It prevents dust accumulation, gives the tiles a luster, and enhances the ability to resist moss growth.
Circular Arc Tile (Roman Tile) vs. Bond Tile: Application Differences
• Bond Tile (Classic Type):
• Features: Hard lines, symmetrical.
• Application: The most common tile type, suitable for modern minimalist style, large-scale laying in residential areas, and is the "value king" with the largest export volume.
• Roman Tile (Arc-shaped):
• Features: Has a Roman-style three-dimensional curvature.
• Application: Suitable for Mediterranean and Spanish architecture. It can form a larger air insulation layer, and its heat insulation performance is better than that of the Bond type, making it very suitable for the high-temperature weather in Mexico.
Professional Common Questions Answered (Technical FAQ)
Q: Will the colored stone tiles make a lot of noise when it rains?
A: No. Although it has a metal base, the natural stone grain coating on the surface has excellent sound absorption effect. The actual test proves that its noise reduction effect is much better than that of traditional color steel tiles.
Q: Will the metal roof attract lightning strikes?
A: This is a misconception. Metal roofs are non-flammable materials and conductive. They can evenly distribute the current, and compared to wood tiles or asphalt tiles, they are safer in the event of lightning strikes.
Q: Will the stone grains fall off over time?
A: High-quality colored stone tiles use high-temperature sintered acrylic resin. If the construction is correct, the stone grains will not fall off in sheets under normal use. We can offer a 30-50-year warranty commitment to our customers.
