The coefficient of friction for Filled Chinas Fujian Andesite tiles can vary depending on several factors such as the surface finish, tile thickness, and the presence of any additional treatments or sealants.

However, as a general guideline, the coefficient of friction for a typical filled Andesite tile can range between 0.5 and 0.8. This means that the tile has a moderate to high level of friction, providing good traction and reducing the likelihood of slipping.

It is important to note that specific information regarding the coefficient of friction for the tiles in question should be obtained from the manufacturer or supplier as they will have the most accurate and up-to-date data for their specific product.
