Angle Square Ruler Measuring Tool

         On inspection of verticality and parallelism as absolute 90° measuring.

     Our granite measuring devices and granite mechanical components are made of  high qualityJinan Blackgranite.Due to their high precision,long duration,good stability and corrosion resistance,they have been more and more used in product inspection of modern industy and such scientific areas as mechanicalaerospace and scientific researches

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.

3 . Wear resistance long service life.                                              Square rulers

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.
