Qual’è la differenza tra le varie superfici in base al coefficiente di scivolosità e di abrasione?

The natural and structured surfaces are more resistant to all types of loads (mechanical, chemical, etc.). Porcelain stoneware with such surfaces can be used in internal and external construction sites and with any degree of traffic intensity. The surfaces of porcelain stoneware: patinated, lapped, lux and polished are recommended for use exclusively indoors, and in general the choice of one rather than another surface is made according to the design solution, the level of pedestrian traffic and to the safety criteria of the designed spaces.
