• Abrasion Resistance (Min): 82.1 La (Ideal for high-traffic flooring and exterior applications)

Chemical Composition (% by Weight)

• Silica (SiO₂): ~50-55% (Major component, adds durability and resistance)
• Alumina (Al₂O₃): ~12-18% (Contributes to strength and color consistency)
• Iron Oxide (Fe₂O₃): ~10-12% (Gives the granite its deep color and durability)
• Calcium Oxide (CaO): ~8-10%
• Magnesium Oxide (MgO): ~5-7%
• Potassium Oxide (K₂O): ~2-4%
• Sodium Oxide (Na₂O): ~2-3%

Mineral Composition (% by Weight)

• Plagioclase Feldspar: ~40-50% (Provides strength and stability)
• Pyroxene (Augite): ~25-35% (Contributes to hardness and color uniformity)
• Olivine: ~5-10% (Enhances durability)
• Iron & Magnesium Minerals: ~5-10% (Adds deep color and resilience)

Applications & Usage

• Interior Flooring & Wall Cladding: Highly durable, scratch-resistant, and elegant for modern and classic designs.
• Countertops & Kitchen Islands: Resistant to heat, stains, and scratches, making it a top choice for residential and commercial kitchens.
• Exterior Façades & Wall Panels: Its durability and weather resistance make it perfect for skyscrapers and modern architectural projects.
• Monuments & Memorials: The deep black color is favored for tombstones and memorials.
• Paving & Landscaping: Ideal for driveways, walkways, and pool surroundings due to its slip-resistant properties.
• Staircases & Steps: Strong and stylish, adding a refined touch to entrances.

Maintenance & Care

• Cleaning: Use mild soap and water; avoid harsh acidic or alkaline cleaners.
• Sealing: Not required due to its low porosity, but optional sealing can enhance its longevity.
• Scratch & Heat Resistance: Highly durable and resistant to daily wear and extreme temperatures.
• Stain Prevention: Naturally resistant, but periodic sealing enhances protection against spills and oils.
