Due to their technical qualities, porcelain is the natural choice material for flooring in areas with a high level of pedestrian traffic, such as shopping centres, offices or public buildings (banks, undergrounds, airports, hospitals, etc.).
Porcelain tiles are ceramic tiles with a water absorption rate of less than 0.5 percent that are used to cover floors and walls.
Large scale production of porcelain tile is undertaken in many countries, with the major producers being China, Italy, Spain and Brazil.
The hardness of the tile is rated from zero to five according to the ASTM C1027 (or ISO 10545-7) test for surface abrasion resistance of glazed tile.
This rating, (sometimes mistakenly called the PEI rating) determines the tiles suitability for various end use conditions.
