Description

Tropical Storm Granite is an exotic natural stone quarried in Angola, characterized by its captivating appearance that resembles a stormy night sky. It features a dark, primarily black background that is richly adorned with irregular veins of white, orange, and gold. This unique pattern creates a dramatic and visually appealing aesthetic, making Tropical Storm Granite a favored material for various architectural and design applications.

Physical and Mechanical Properties:

  • Water Absorption:Typically low, around 0.25% to 0.34%. This low water absorption rate makes the stone resistant to moisture-related damage.
  • Density:Approximately 2,690 to 2,750 kg/m³. The high density contributes to the material's robustness and durability.
  • Flexural Strength:Averages between 12 to 13 MPa. This indicates good resistance to bending and deformation under load.
  • Compressive Strength:Generally ranges from 200 to 230 MPa, showing the stone's ability to withstand substantial pressures without cracking.
  • Hardness:Falls around 6 to 7 on the Mohs scale, making it a relatively hard material, suitable for high-traffic areas.
  • Porosity:Very low porosity, which enhances its durability and stain resistance.
  • Slip Resistance:Varies with surface finish; typically, honed or flamed finishes offer higher slip resistance.

Chemical and Mineral Composition (% by weight):

  • Quartz: 20-30%
  • Feldspar (including Plagioclase and Potassium Feldspar): 50-60%
  • Biotite and Mica: 10-15%
  • Iron Oxides and Other Minerals: 5-10%

These compositions contribute to the stone's color, durability, and texture.

Usage:

  • Interior Flooring: Excellent for residential and commercial spaces due to its strength and aesthetic appeal.
  • Countertops: Popular choice for kitchen and bathroom countertops; the dramatic veining adds elegance.
  • Wall Cladding: Offers a luxurious and sophisticated look to interiors and exteriors.
  • Fireplaces and Feature Walls: Enhances the visual focal point in living areas.
  • Outdoor Spaces: Suitable for patios and pathways when appropriately finished.

Maintenance:

  • Regular Cleaning: Use a damp cloth and mild detergent. Avoid acidic or harsh chemicals to maintain polish and prevent etching.
  • Sealing: Recommended annually to protect against stains and scratches.
  • Immediate Stain Removal: Wipe spills promptly to prevent potential staining.

Available Common Surface Finish Options:

  • Polished: Provides a high-gloss shine, enhancing the stone’s color and pattern.
  • Honed: Offers a smooth, matte finish ideal for areas where slip resistance is critical.
  • Flamed: Creates a textured surface that increases slip resistance, ideal for outdoor applications.
  • Bush-Hammered: A more rugged texture for a rustic appearance, also enhancing slip resistance.

Tropical Storm Granite is a versatile stone that brings elegance and durability to any project. Its unique appearance and robust properties make it suitable for a wide range of applications, from luxurious interiors to durable outdoor installations. Proper maintenance ensures its beauty and functionality are retained over time.
