The main materials used to decorate stairs are usually wood, stone, etc. Marble is the common stone used for stair steps. Marble is very rich in design and color. After protection, the gloss is more high-end atmosphere.
Marble itself is not easy to deform, with high hardness, strong grindability, meticulous organization, falling off of impacted grains, no burr on the surface, and no influence on the plane accuracy. It can ensure long-term non deformation, small coefficient of linear expansion, and high mechanical accuracy.
