Adopted high quality "Jinan Qing" natrual mateirial of granite, granite surface plate is manufactured by mechanical processing and manual polishing2. It dosen't only own the interest of black gloss, precise construction, and outstanding characters - nice stability, high strength and hardness, etc. But also it is no rust, acid & alkali-proof, no magnetization, nice abrasion resistance and Can keep stable at normal or high tempreture.3. the main mineral ingredients of granite are pyroxene, anorthose, less olivine, black mica and less magnetite. Aging through hundreds of millions years, the granite can still retain even character, stable, high strength and hardness, and can keep high precision at Heave duty. It is suitable for industrial production and measuring works at laboratory.Usage:Lineation, Measurement.
