The "GOLD STONE"brand of granite measuring tools have the following characteristics:

1  High precision  reliable stability resistant to deform and guaranteed accuracy under normal ambient temperature.

2  No-rust and anticorrosion.                                                        General mechanical components

3  Wear resistance long service life.

4  Any cutting or scraching for working surface does not bring about roughedgeswhich might  influence its measuring precision.

5  Non magnetization.

6  Glossy surface  without sluggishness when the workpieces or tools are moving on it.
