Specification :

Material: Granite mainly consists of pyroxene, pkaguickase, a small amount of olivine , biotite and micromagetite.Its structure is hard and compact.It has solidified in a natural way over millions of year resulting in his hogeneity , reliable stability, high strength and super hardness .It can keep relatively high precision under heave load.It’ s suitable for measuring applications in factories and laboratories.
