Preface:
Quartz from DB Group is highly renowned for their quality & pricing. DB Group owns multiple mining and processing facilities to produce various qualities of Quartz. We offer quartz in Lumps, Powder & Grits.
Quartz from our mines are supplied to Ceramic, Frit, Glass, Solar Panels, Composite quartz Industry. Other than industrial use, quartzite slabs are being used aesthetically used in Interior designing and for Elevation too.
