Premium natural igneous stone tiles offering exceptional durability, compressive strength (130-180 MPa), and minimal water absorption (<0.4%) for interior and exterior architectural applications

Overview
Executive summary

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.
