The granite inspection platform is made of high-quality Jinan green stone, which is processed by machinery and finely ground by hand. It has high precision no deformation, good stability and long service life, and is suitable for measurement work in machine factories and laboratories.

The main mineral composition of Jinan granite is pyroxene, plagioclase, biotite, and a small amount of magnetite with a black color, precise structure, uniform texture, good stability, high strength and hardness, and can maintain high precision under heavy load.

High precision, good stability, not easy to deform, and can guarantee measurement accuracy at room temperature.

No rust, acid and alkali resistant, no special maintenance required.

Good wear resistance and long service life.

• Scratches and dents on the working surface do not affect the accuracy of measurement.
• No magnetization problem
• It can slide smoothly in the middle of the measurement without any sense of friction.
