The "TAI 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.
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.
This is our normal size( standard issue size), for inspecting the straightness and flatness. Welcome your inquiry for specification.
