Granite taken from high quality underground rock, after millions of years of natural aging, morphology is extremely stable, without fear of deformed because of the temperature difference between the conventional. Granite platform after rigorous physical testing and selection of granite, Crystal fine, hard. Because granite is non-metallic materials, and no magnetic response, there is no plastic deformation. Granite platform of its high hardness, good accuracy. Due to the granite often contain radioactive material, when granite is used to measure the radiation level and confirm its use. Granite, China is rich in resources, variety, used since ancient times in civil engineering.
