Description
Black and grey granite tiles are dimensioned natural stone products quarried from igneous rock formations, primarily composed of quartz (20-60%), feldspar (35-65%), and mica/amphibole minerals. Available in polished (high gloss) or honed (matte) finishes across standard thicknesses of 10mm, 15mm, 20mm, and 30mm. The material exhibits superior mechanical properties including high compressive strength, excellent abrasion resistance, and thermal stability up to 350°C. Suitable for flooring, wall cladding, external paving, and bench tops in residential and commercial applications.

Granite has been used in construction since ancient Egypt (2580 BC - Great Pyramid of Giza). Modern Australian granite industry established 1880s with Harcourt (Victoria) and Queensland quarries. Technological advances include diamond wire cutting (1970s), CNC processing (1990s), and water-jet cutting (2000s). Current innovations focus on ultra-thin veneers, recycled water systems, and nano-sealers for enhanced performance.
