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.

The aluminum, typically around 5 - 15% by weight, offers enhanced resistance to corrosion, especially in humid or corrosive environments. The zinc, with a proportion of 85 - 95% by weight, acts as a sacrificial anode, protecting the steel from rust. This combination provides a strong and durable base for the roofing sheet, with the steel contributing high tensile strength, usually in the range of 300 - 500 MPa, ensuring it can withstand various mechanical stresses during installation and service life.</li><li>Colorful natural stone chips: Derived from natural minerals like quartz, feldspar, and mica. Quartz, with a Mohs hardness of around 7, provides excellent abrasion and impact resistance. The natural stone chips not only add an aesthetically pleasing texture and color but also offer protection against UV radiation and minor impacts. They are adhered to the aluminum - zinc plate using a high - quality acrylic resin.</li><li>Acrylic resin: Serves as the adhesive that bonds the stone chips to the aluminum - zinc plate. It provides a strong and durable bond, ensuring the long - term integrity of the roofing sheet. Acrylic resin also has good weather - resistance properties, protecting the bond from degradation due to moisture, sunlight, and temperature fluctuations.</li></ul> |
| Size |
1340*420mm. This size is designed to optimize the balance between coverage area and ease of handling during installation. Larger sizes can cover more area per sheet, reducing installation time and the number of joints, but also need to be manageable for workers to transport and install on the roof. |
| Effective Size |
1290*370mm. This is the actual area that contributes to the roof coverage after installation. The difference between the size and effective size accounts for the overlap regions between adjacent sheets, which are crucial for waterproofing and structural stability. The overlap ensures that water is directed away from the roof structure and that the sheets work together as a unified system. |
| Thickness |
Available in 0.35mm, 0.4mm, 0.45mm, 0.5mm, 0.55mm, 0.6mm. Different thickness options are provided to meet diverse requirements. Thinner sheets like 0.35mm may be suitable for areas with mild weather conditions or where cost - savings are a priority, while thicker sheets such as 0.6mm are more appropriate for regions with extreme weather, heavy snow loads, or high - wind areas, offering enhanced strength and protection. |
| Weight / Tile |
2.3 - 3.8kgs. The weight is carefully balanced to be light enough for easy handling during installation, reducing the physical strain on workers. At the same time, it is substantial enough to ensure stability on the roof, especially during high - wind events. The weight also affects the overall load - bearing requirements of the roof structure. |
| Color |
<ul><li>Ordinarily 15 colors in color chart: The color chart offers a wide range of options to match different architectural styles and customer preferences. Colors can range from earthy tones like browns and beiges for a natural look, to bold colors for a more modern or eye - catching appearance.</li><li>Can be customized: For customers with specific color requirements, the roofing sheets can be customized to match a particular color scheme, such as corporate colors or to blend with the surrounding environment.</li></ul> |
| Coverage Area/Tile |
0.48m². This value is crucial for accurately calculating the number of sheets needed for a given roof area. A larger coverage area per tile means fewer tiles are required, which simplifies the installation process and can potentially reduce costs associated with materials and labor. |
| Sheet/SQ.M |
2.08 pieces. This indicates the number of sheets required to cover one square meter of the roof. It is an essential parameter for estimating the quantity of materials needed for a roofing project, which is vital for budgeting, procurement, and project planning. |
| Certificate |
<ul><li>ISO9001: This international standard for quality management systems ensures that the manufacturing process of the roofing sheets adheres to high - quality standards. It covers aspects such as quality planning, control, assurance, and improvement, guaranteeing that the products are consistent in quality and meet customer expectations.</li><li>SGS: SGS is a globally recognized inspection, verification, testing, and certification company. Their certification validates that the roofing sheets meet specific quality, safety, and environmental standards, as tested and inspected by their independent experts.</li><li>BV: Bureau Veritas is another well - known international certification body. Their certification attests to the quality, reliability, and compliance of the roofing sheets, providing customers with confidence in the product's performance and adherence to industry - recognized norms.</li></ul> |

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.
