The tone of cave stone is mostly beige, which makes people feel mild, rich in texture and clear stripes, which makes the decorated buildings often have a strong cultural and historical charm.
Due to the existence of a large number of holes, the natural cave stone has low bulk density, increased water absorption, decreased strength, and poor performance uniformity. In particular, the dispersion of bending strength is very large. Some will break in the process of handling, and it will face high risk when used in the outer wall.
The cave stone style developed by yunshimei has rich colors, unique texture, special hole structure, density, concave convex harmony, good decorative performance and excellent safety, making it possible to apply the outer wall in a large area.
