Product Description
Metal tile with stone chips coating is a specific type of metal roofing material that features a layer of stone chips adhered to the surface of a metal tile through a coating process. Here is a detailed account:
Structure and Components
- Metal Substrate: Typically, the base of this kind of tile is made from metals like high-quality galvanized steel or aluminum-zinc alloy. These metals are chosen for their strength, which enables the tile to bear various loads and pressures. They also offer excellent corrosion resistance, ensuring the tile's durability even in harsh environmental conditions.
- Coating Layer: Between the metal substrate and the stone chips, there is a coating layer. This is usually composed of a special adhesive or resin material. Its main function is to firmly bond the stone chips to the metal surface and provide additional protection to the metal substrate, enhancing its resistance to rust and other forms of damage.
- Stone Chips: The stone chips used are usually natural minerals such as granite, basalt, or slate. These are carefully selected for their uniform particle size and rich colors. The stone chips not only add an aesthetically pleasing natural texture to the tile but also contribute to its performance in terms of heat insulation, sound insulation, and UV resistance.

Raw materials . Aluzinc Electroplated Steel
- Composition
- Aluzinc electroplated steel is mainly composed of a steel substrate with a coating of an alloy consisting of aluminum, zinc, and a small amount of silicon. Typically, the alloy coating contains about 55% aluminum, 43.4% zinc, and 1.6% silicon.
- Physical Properties
- Density: The density of aluzinc electroplated steel is approximately 7.85 g/cm³, which is similar to that of ordinary steel, but the specific gravity may vary slightly depending on the thickness of the coating and the specific composition.
- Tensile Strength: It generally has a tensile strength in the range of 300 - 500 MPa, providing good mechanical strength and enabling the roof tiles to withstand certain external forces and pressures without easy deformation or breakage.
- Elongation: The elongation is usually around 20% - 30%, which means it has a certain degree of flexibility and can adapt to some thermal expansion and contraction changes and building movements.
- Coating Thickness: The thickness of the aluzinc coating is typically in the range of 15 - 25 μm. This thickness ensures good corrosion resistance and protection for the steel substrate.
- Chemical Properties
- Corrosion Resistance: The aluminum in the coating forms a dense aluminum oxide film on the surface in the air, which can effectively prevent the penetration of oxygen and water, thereby significantly improving the corrosion resistance of the steel. In salt spray tests, aluzinc electroplated steel can usually withstand more than 1000 hours without obvious rusting, which is much better than ordinary galvanized steel.
- Oxidation Resistance: Due to the presence of aluminum and zinc, the material has good oxidation resistance at high temperatures. It can maintain stable performance in an environment of up to 300 - 400°C for a certain period without serious oxidation and degradation.
Natural Stone Chips
- Composition
- Natural stone chips used for roof tile coatings are usually made from various natural stones such as granite, basalt, and slate. Granite mainly consists of quartz, feldspar, and mica. Basalt is mainly composed of plagioclase and pyroxene. Slate is mainly composed of clay minerals and mica.
- Physical Properties
- Density: The density of different natural stone chips varies. For example, granite has a density of about 2.6 - 2.75 g/cm³, basalt has a density of around 2.8 - 3.3 g/cm³, and slate has a density of approximately 2.7 - 2.9 g/cm³.
- Hardness: On the Mohs hardness scale, granite typically has a hardness of 6 - 7, basalt has a hardness of about 5 - 6, and slate has a hardness of 2 - 4. The relatively high hardness of granite and basalt makes the stone chips wear-resistant and able to withstand external friction and impacts.
- Color: Natural stone chips offer a wide range of colors. Granite can be white, pink, gray, black, etc. Basalt is usually black or dark gray. Slate can be gray, green, purple, and other colors, providing rich color options for roof tile coatings to meet different aesthetic requirements.
- Particle Size: The particle size of natural stone chips is generally in the range of 1 - 5 mm. A suitable particle size ensures good adhesion to the coating and a uniform and beautiful surface effect.
- Chemical Properties
- Acid and Alkali Resistance: Granite and basalt are relatively acid and alkali resistant. They can resist the erosion of weak acids and alkalis to a certain extent and maintain stable chemical properties in different environmental conditions. However, slate may have relatively lower acid and alkali resistance due to its different composition.
- Weather Resistance: Natural stone chips have good weather resistance. They can withstand long-term exposure to sunlight, rain, wind, and snow without significant color fading or decomposition. The minerals in the stone chips are stable and can maintain the performance and appearance of the roof tile coating for a long time.
Our tile usual profiles
1. Classic
This tile has a simple, wavy profile. It likely offers a traditional and versatile look, suitable for a wide range of architectural styles. With the option of customized colors, it can be tailored to match different building exteriors. Its thickness ranges from 0.3 - 0.6mm, providing durability while remaining lightweight.
2. Wood Shake
Designed to mimic the appearance of natural wood shake shingles, this profile adds a rustic and charming aesthetic to a roof. The textured surface created by the stone coating enhances the wood - like look, giving a warm and inviting feel to the building. Like other tiles in the range, it comes in the standard thickness range and can be colored as per customer needs.
3. Ridge Tiles
These are specialized tiles used for the ridges of a roof. They are crucial for protecting the ridge area from water infiltration and providing a finished look. The unique shape helps in proper alignment and sealing at the roof's peak.
4. Roman Tiles
They have a distinct curved profile with a wavy top and bottom edge. The design gives a sense of elegance and grandeur, reminiscent of traditional Roman - style roofing. This style can add a touch of historical charm to modern or heritage - inspired buildings.
5. Big Roman
Similar in concept to the Roman tiles but with a larger size. The increased dimensions may make a bolder visual statement on the roof, and they can cover a larger area per tile, potentially reducing installation time.
6. Milano
The Milano profile features a smooth, wavy design. It likely offers a contemporary and sleek appearance, making it suitable for modern architectural designs. The uniform wave pattern can create a harmonious look across the roof surface.
7. Shingle
This profile replicates the look of traditional asphalt shingles but with the added benefits of a stone - coated metal tile. It usually has a more segmented and layered appearance, which can add depth and texture to the roof.
8. Tudor
The Tudor - style tile has a more complex and textured profile. The pattern, combined with the stone coating, gives it a unique and sophisticated look, often associated with Tudor - style architecture. The water droplets on the tile in the image suggest its good water - repellent properties.
