Granite products have the following advantages:

1. High precision, stability, and resistance to deformation, ensuring measurement accuracy at room temperature.

2. No rust, acid and alkali resistance, no need for special maintenance.

3. Good wear resistance and long service life.

4. Scratches and bumps on the work surface do not affect measurement accuracy.

5. There is no magnetization issue.

6. Smooth sliding and no sense of stagnation during measurement.
