Intruction
Polished Porcelain Tile is fully-vitried porcelain body tile with mirror-like surface and rectified edging in usual size 600*600, 800*800, 1000*1000 and 600*1200mm. It is widely used in most indoor and outdoor wall and floor decoration due to its strong hardness and wear resistance characters. With advanced pattern penetrating technology, Polished porcelain tile could be produced in many different patterns e.g. Stone-like patterns, Wood-like pattern …etc.
Nowadays, Chinese Polished Porcelain tile is in top quality of the world with much higher quality standards than Europe, especially in surface flatness, straightness edge, straight angles and wear parameters, Chinese standard is in 2 times numerical higher than European standard.
Presently, Chinese export polished porcelain tile occupies nearly 50% of the total volume in world-wide market with regular size 600x600mm and 800x800mm. The large size tile e.g. 1000x1000mm and 600x1200mm has not yet became a trend in Export due to the environmental impact, strength and breakage rate causing by long transportation.
