Comprised mainly of quartz, Rongguan Engineered Quartz is hard and condense, it is superficial hardness is very high(mohs hardness:6-7), is resistant to scratch, wear, shock, rupture and compression, and have excellent heat resistance, corrosion resistance, and stain resistance, which are advanced to artificial marble. Not being distorted, split, and being resistant to discoloration, fading. It is durable and maintenance free. Furthermore, it does not contain any pollution and radiation, thus is an environmental friendly building material Our slab size : 2400*1200mm 3000*1400mm thickness: 12mm,15mm,18mm,20mm
