◎Non-toxic, hygienic, belong to green environment-friendly construction material◎No fur, Strong water capacity◎Service life can be over 50 years◎Corrosion resistance: Except a handful of oxidant, it can be resistant to many kinds of chemical medium corrosion. It will not rust, not corrode, not breed bacteria, and has no electrochemical corrosion, as well as can avoid the macular rust of wash basin and bathtub caused by pipeline corrosion, and the pipeline blockage caused by corrosion and scaling.◎The single-root automatic weighing system, which is developed independently by Tonzo, ensures that each pipe reaches the standard thickness, and the special heat treatment process can effectively reduce the pipe brittleness caused by low temperature.
