We are professional in offering a qualitative range of Straight edges that are used for checking surface flatness of large precision area. Straight Edges have been designed well and ribbed in the best manner to retain their accuracy under varying conditions and are as light as possible without sacrificing rigidity.
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
