Chinese Quartzite is a very strong stone but is usually not found in large bodies suitable for quarrying. For this reason flag sizes are generally smaller. The thickness is dictated by the bed depth, approximately 30mm, and although this may seem thin for commercial paving, this material’s excellent flexural strength combined with the correct sub-base make for a hard wearing but attractive surface. Colours range from silvery grey with hints of green, pink and red through to a shimmery black. Chinese Quartzite has a distinctive sparkle from the tightly interlocking grains of quartz contained within.
