We are professional in manufacturing and exporting all kinds of granite products.
granite V blocks : 2 blocks make up one set. Parallelism of base and V groove of the 2 blocks is assured.
Secular distortion, and temperature change effects are minimal. It is wear resistant and does not rust in addition to other special features.
Very convenient for round objects, and other types of inspection or as supporting block (Rectitude stand)
V Groove is 90 degrees
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
