Sierra Brown Granite is a medium to coarse-grained natural stone originating from Brazil. Known for its rich mocha-brown base, it is elegantly embellished with black and gray speckles and highlighted by golden-yellow hues, giving it a warm and inviting appearance. This exquisite granite is often sought after for its aesthetic appeal and durability.

Physical and Mechanical Properties:

• Water Absorption:Typically around 0.2% to 0.3%, indicating low porosity and high density.

• Density:Approximately 2,680 to 2,730 kg/m³. This value signifies its sturdy nature and suitability for various applications.

• Flexural Strength:Ranges from 8 to 12 MPa, allowing it to withstand bending forces without cracking.

• Compressive Strength:Generally between 169 and 189 MPa, making it highly resistant to crushing forces.

• Hardness:Mohs hardness scale rating between 6 and 7, reflecting its resistance to scratches and abrasions.

• Porosity:Low porosity typically under 1%, contributing to its strength and water resistance.

• Slip Resistance:Varies based on the finish, but generally moderate to high, especially when flamed or honed.

Chemical and Mineral Composition:

• Quartz:Approx. 25-35%

• Feldspar (Orthoclase and Plagioclase):Approx. 40-50%

• Biotite and Muscovite (Micas):Approx. 5-10%

• Iron Oxides and Accessory Minerals:Approx. 1-5%

• Others:Includes trace amounts of magnetite, zircon, and other minerals.

Usage:

• Countertops: Ideal for kitchen and bathroom countertops due to its hardness and aesthetic appeal.
• Flooring: Suitable for both indoor and outdoor flooring, providing durability and beauty.
• Wall Cladding: Used effectively as exterior and interior wall cladding.
• Outdoor Applications: Perfect for monuments, steps, and other architectural structures requiring weather resistance.

Maintenance:

• Cleaning: Regular cleaning with mild soap and water; avoid acidic or abrasive cleaners.
• Sealing: Annual sealing recommended to maintain its resistance to staining and moisture penetration.

Cutting Sizes (cm):

• Slabs: Typically available in 2 cm and 3 cm thicknesses.
• Tiles: Commonly cut into sizes such as 30x30, 30x60, 60x60cm, or custom sizes based on project requirements.

Available Common Surface Finish Options:

• Polished: Offers a glossy surface that highlights the stone's colors and patterns.
• Honed: Provides a matte finish with a smooth surface, lacking the reflective sheen.
• Flamed: Achieves a rough texture, enhancing slip resistance, suitable for outdoor applications.
• Brushed: Produces a textured surface with an aged appearance, offering a softer feel.

Overall, Sierra Brown Granite is prized for its versatility, durability, and captivating appearance, making it an excellent choice for a wide range of architectural and design applications.
