G386 Granite is a medium-coarse-grained red granite quarried in Shidao, Shandong Province, China. It is a popular natural stone known for its durability, aesthetic appeal, and versatility in construction and design applications. Below is a detailed description of its characteristics, properties, and usage:

Texture and Pattern

Texture: Medium to coarse-grained, with a consistent and uniform texture.

Pattern: Features a rich red background with subtle variations in tone and occasional darker mineral flecks, giving it a natural and elegant appearance.

Physical and Mechanical Properties (Test Results)

Density: Approximately 2.6–2.8 g/cm³ (varies slightly depending on the specific quarry batch).

Water Absorption: Typically 0.2–0.4% by weight, indicating low porosity and high resistance to moisture.

Compressive Strength: Around 150–250 MPa, making it highly durable and suitable for heavy-duty applications.

Flexural Strength: Approximately 10–15 MPa, ensuring good resistance to bending and cracking.

Abrasion Resistance: High, making it suitable for high-traffic areas.

Chemical and Mineral Composition (% by Weight)

Silica (SiO?): ~70–75%

Alumina (Al?O?): ~10–15%

Iron Oxide (Fe?O?): ~3–5% (contributes to the red color)

Calcium Oxide (CaO): ~1–2%

Magnesium Oxide (MgO): ~1–2%

Potassium Oxide (K?O): ~2–4%

Sodium Oxide (Na?O): ~2–3%

Other Trace Minerals: ~1–2%

Usage

G386 Granite is widely used in both interior and exterior applications due to its durability and aesthetic appeal. Common uses include:

Flooring and Wall Cladding: Suitable for indoor and outdoor spaces.

Countertops and Vanity Tops: Ideal for kitchens and bathrooms due to its resistance to scratches and stains.

Paving and Landscaping: Used for driveways, walkways, and garden features.

Monuments and Decorative Items: Often used for memorials, statues, and ornamental pieces.

Maintenance

Cleaning: Use a pH-neutral stone cleaner and avoid acidic or abrasive cleaners to prevent surface damage.

Sealing: Apply a high-quality penetrating sealer periodically to enhance stain resistance and maintain the stone's appearance.

Protection: Use coasters or mats under hot or sharp objects to avoid scratches or heat damage.

Cutting Sizes (Standard Dimensions)

Slabs: Typically 240–300 cm (length) x 120–180 cm (width) x 2–3 cm (thickness).

Tiles: Common sizes include 30x30 cm, 60x60 cm, and 60x120 cm with thicknesses of 1–2 cm.

Custom Sizes: Available upon request for specific project requirements.

Surface Finish Options

G386 Granite can be finished in various ways to suit different design needs:

Polished: High-gloss finish that enhances the stone's color and pattern.

Honed: Matte finish with a smooth surface, ideal for a more subdued look.

Flamed: Textured, non-slip surface created by high-temperature heating, suitable for outdoor use.

Bush-Hammered: Rough, textured finish for a rustic appearance.

Sandblasted: Matte finish with a slightly rough texture, often used for decorative purposes.

Advantages

Durability: Resistant to weathering, abrasion, and heavy loads.

Aesthetic Appeal: Unique red color with natural variations.

Versatility: Suitable for a wide range of applications.

Low Maintenance: Requires minimal upkeep when properly sealed.

G386 Granite is a premium natural stone that combines beauty and functionality, making it a popular choice for architects, designers, and homeowners worldwide. If you need further details or specific test reports, feel free to ask!
