The production process white marble slab uses the high quality natural Dali stone material after the machine-finishing, the handwork researches in thorough detail becomes. The black gloss, the structure precise quality of material is even, the stability is good. The intensity of White Marble Slab is big, degree of hardness is high. And has: It is not rusty bears the acid and alkali, not to magnetize, not to change form, the resistance to wear well and so on merits. Can maintain stable under the heavy load and the general temperature. The White Marble Slab is the precise datum measuring tool which makes with the natural lithical material, to the instruments and meters, the precision tool, the mechanical workpiece's examination, is the ideal reduced plane.White Marble Slab general warm under maintain the high accuracy at the heavy load, and has not rustily, bears the acid and alkali, the resistance to wear, does not magnetize, does not change form and so on merits. The granite slab is suitable for the Machine shop measuring tool.
