              Sandstone use

              Nov 06, 2019

              Sandstone is the most widely used stone material by human beings. Its noble and elegant temperament and natural and environmentally friendly features have made wonderful blossoms in the history of architecture.

              In the past, sandstone was very laborious for construction purposes, because the cutting machines and processing machinery of the quarry were relatively backward. In recent years, these conditions have improved, and we are gradually able to provide customers with high-quality products based on customers' color requirements with the highest level of expertise.
