Physical properties of Wulian gray granite: Wulian gray granite stone can withstand various external forces such as gravity, wind, vibration, temperature changes, wear, and load, which requires high strength of the stone.
The chemical properties of Wulian gray granite require that the stone has considerable resistance to chemical erosion such as weathering, hydration, dissolution, dehydration, acidification, reduction, and carbonate. When selecting directional stones such as slate and shale, attention should be paid to their structural strength in different directions.
