Granite measuring tools have the following characteristics

1.       high precision reliable stability resistance to deform and guaranteed accuracy under normal ambient temperature.

2.       No-rust and anticorrosion

3.       wear resistance long service life

4.       any working surface cutting or scratching dose not bring about rough edges which  might influence its measuring presicion.

5.       nonmagnetization.

6.       gloosy surface without sluggishness when the workplaces or tools are moving on it .
