What are the differences in tile prices on the market?

The price difference of tiles on the market is very large now. Take 600 and 800 ceramic tiles as an example. From 10 bucks to several hundred bucks, what are the differences?

Wear resistance is the most important indicator of the use of polished tiles. In general, the wear resistance of polished tiles is controlled at 6-7 degrees. There is no problem in the family for 6-10 years, and it can be used in shopping malls for 5 years. A polished tile with a 4 to 5 degree of wear resistance may only be used for 5 years at home, and the mall may have less. Grades 6-7 have a very high content of silt purchased from the polished tiles, and the cost is very high. It costs about 300 yuan and a ton. The 4-5 sediment content is lower, so the price is cheaper, there may be more than 100 yuan a ton, 3-4 levels are even lower, it is prone to secondary pollution. Some polished tiles are polished twice: rough polished, fine polished, and some polished only once. In order to make the tile flatness and gloss better, it has to be polished twice, and the speed is slow, the slower the speed, the better the flatness.
