Golden Coast Granite

Golden Coast Granite is a unique and appealing natural stone, quarried in Brazil, known for its warm, inviting color palette and versatile usage. Below are detailed descriptions and relevant information about its physical and mechanical properties, chemical and mineral compositions, usage, maintenance, cutting sizes, and surface finish options.

Physical and Mechanical Properties:

• Water Absorption: Approximately 0.24% to 0.4%, indicating low porosity and good resistance to moisture.
• Density: Around 2,680 kg/m³ to 2,730 kg/m³, which is typical for Brazilian granites, contributing to its durability.
• Flexural Strength: Ranges from 9.8 MPa to 14.5 MPa, indicating good resistance to bending and tension.
• Compressive Strength: Generally between 170 MPa to 180 MPa, showcasing its robust nature.
• Hardness: Classified at around 6-7 on the Mohs scale, showing substantial scratch resistance.
• Porosity: Low, less than 1%, which enhances its suitability for high moisture areas.
• Slip Resistance: Moderate to good when honed or polished, improving with special finishes for increased safety.

Chemical and Mineral Compositions (% by weight):

• Quartz: 30% - 40%, contributing to its hardness and scratch resistance.
• Feldspar: 30% - 40%, essential for the granite’s durability and resistance to weathering.
• Mica: 5% - 10%, adding to its aesthetic appeal with shiny specks.
• Iron Oxides and Other Minerals: 5% - 10%, responsible for its warm yellow to golden hues.
• Silica (SiO2): Predominantly present, between 60% - 70%.

Usage:

• Interior Applications: Suitable for countertops, flooring, wall cladding, and fireplace surrounds due to its durability and aesthetic qualities.
• Exterior Applications: Ideal for facades, paving, and other outdoor uses due to its weather-resistant properties.
• Public Spaces: Used in high-traffic areas like airports and shopping malls given its strength and attractive appearance.

Maintenance:

• Regular cleaning with mild soap and water is sufficient.
• Sealing recommended every year or two to maintain stain resistance.
• Avoid abrasive cleaners to prevent surface dullness.

Cutting Sizes (cm):

• Slabs typically available in widths of 60cm to 90cm and lengths of 180cm to 300cm.
• Custom cutting sizes available on request, accommodating various project needs.

Available Common Surface Finishes:

• Polished: Provides a glossy finish that enhances color and pattern.
• Honed: Offers a matte finish with a smooth surface for a more subdued appearance.
• Brushed: Provides a textured surface with a slightly weathered look.
• Flamed: Imparts a rough texture ideal for outdoor slip resistance.

Golden Coast Granite combines aesthetic versatility with robust mechanical properties, making it a favored choice for both functional and decorative applications in diverse architectural and design projects. Its ability to take a high polish and its varied finish options make it adaptable to various stylistic preferences while maintaining its natural beauty and durability.
