Originating from the Fujian province in China, this granite is popular for its blend of beauty and robustness, making it suitable for various applications.

Physical and Mechanical Properties:

• Water Absorption:Typically low, around 0.2% to 0.4%, indicating good resistance to moisture.

• Density:Approximately 2.63 to 2.67 g/cm³, indicating a compact and solid structure.

• Flexural Strength:Ranges from 8 to 12 MPa, showcasing its ability to withstand bending forces.

• Compressive Strength:Typically between 155 to 167 MPa, implying strong load-bearing capabilities.

• Hardness:Rated around 6 to 7 on the Mohs hardness scale, suggesting notable scratch resistance.

• Porosity:Low porosity, contributing to its durability and stain resistance.

• Slip Resistance:Varies depending on the finish, with honed and flamed surfaces providing better slip resistance.

Chemical and Mineral Composition (approximate % by weight):

• Quartz: 25-30%
• Feldspar (predominantly K-Feldspar): 50-60%
• Biotite: 5-10%
• Muscovite and Hornblende (combined): 5-8%
• Other Minerals: 2-5%, including minor traces of minerals contributing to color variations.

Applications and Usage:

• Kitchen Countertops: Durable and aesthetically pleasing for kitchens.
• Flooring: Ideal for both residential and commercial settings due to its wear resistance.
• Wall Cladding: Used for façade cladding, providing insulation and visual appeal.
• Staircases: Durable enough to withstand high traffic.

• Bathroom Vanities: Resistant to water and humidity.

Available Common Surface Finishes:

• Polished: High-gloss finish that enhances color and pattern.
• Honed: Smooth, matte finish providing a contemporary look.
• Flamed: Rough texture, ideal for outdoor and non-slip surfaces.
• Bush-Hammered: Unique texture for exterior paving.
• Leathered: Soft sheen and a textured touch, gaining popularity for countertops.

Cutting Sizes (cm):

• Tiles: Common sizes include 30x30, 30x60, 60x60, and custom sizes.
• Countertops: Typically cut to 2 cm or 3 cm thickness, with lengths varying according to project demands.
• Slabs: Usually available in a range of sizes, generally from 120x240 cm to 180x300 cm.

Maintenance:

• Cleaning: Clean regularly with a mild detergent and warm water. Avoid acidic or abrasive cleaners.
• Sealing: Periodically apply a granite sealant to maintain stain resistance.
• Polishing: Occasional polishing can restore and maintain surface shine.

G639 Granite, with its appealing coloration and robust properties, is versatile for numerous architectural and design applications, providing both aesthetic charm and longevity.
