Granite plate material from the underground rock layer, after millions of years of natural aging, the shape is extremely stable, do not worry about the regular temperature difference and deformation.
1. The granite plate is taken from the underground rock layer. After millions of years of natural aging, the shape is extremely stable, and there is no need to worry about deformation due to regular temperature difference.
2, granite slab by strict physical test and selection of marble material, crystalline fine, hard texture.
3, because marble is a non-metallic material, magnetic reaction, no plastic deformation.
4, the main mineral composition is pyroxene, plagioclase, a small amount of olivine, biotite and trace magnetite, black color, structure precision, can maintain high precision under heavy load.
5, stone specific gravity, compressive strength, elastic grinding, linear expansion coefficient, water absorption rate of 0.13, Shore hardness of HS70 or more.
