We specialize in offering a wide variety of granite squares. These granite squares are available in different angle ranging from 45 to 90 degrees. We make use of high grade cast iron to design these precision tools. Our range of Granite square is used for measuring the exact accuracy in terms of squareness and flatness respectively.

Our range includes granite square, precision granite square, granite block master and granite square triangular.

The physical properties of the granite are as follows:

1.Granite mainly consists of pyroxene, plagioclase, a small amount of olivine, biotite and

micromagnetite.
2. Its structure is hard and compact.
3.It has solidified over millions of years resulting in its homogeneity, reliable stability, high

strength and super hardness.
4. Can keep high precision under heavy load.
5. Be suitable for measuring applications.

6. Specific gravity:2970-3070kg/m3.

7. Compressive strength:245-254N/mm2.

8. Elastic modulus:1.27-1.47 N/mm2.

9. Linear expansivity:4.61*10-6/Celsius degree.

10. Water absorption:<0.13%

11. Shore hardness:Higher than Hs70.
