Introduction of quartz surface Quartzsurface is a kind of artificial stone which mainly consist of quartz crystals, and mixed with high-strength resins and other additives, The materials are mixed in a strict scientific rate, and processed through vacuum compressing, pulsing vibration, polymerization, solidification and polishing with the professional equipments. Our quartz surface has the characteristics which are high hardness, acid and alkali resistance and abrasion resistance. Ourquartzsurfacecan be widely used for table top,counter top,vanity top,flooring,stair,etc.2.
