The product of T Series is named Polycrystalline Double Loading, due to a kind of crystal particle added during the computerized burning process.With its high concentration of particals, its polishing degree and stain-proof capacity is superior to the normal polished tiles.Its difference with other series of double loading is not in its physical structure,but in its surface design,which looks more closer to natural stone.Therefore, we call it the third generation of double loading porcelain tiles.
