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 rough edges which might   influence its  measuring precision.

5  Non magnetization.

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