As one of the core components of chemical construction, pipeline plays a vital role in residential building. At present, high-rise residential buildings are in the majority of commercial and residential buildings, and the pipeline system is prone to damage and water leakage problems during the rainstorm season or the failure of drainage. At the same time, with the continuous deepening of the concept of green energy saving, users are demanding more and more of all kinds of pipes and fittings.

   Faced with such competition in the building materials industry, as the integrated manufacturer of pipeline system, Tonzo adheres to the business philosophy of "healthy, efficient, pragmatic, innovative", and after more than a year of research and development, Tonzo has produced a kind of high-rise building rainwater drainage system, which has won the national patent certification (patent number: ZL201220597525.4), and has fully independent intellectual property rights. The system has solved the problems of big noise, easy-aging and high cost for the traditional high-rise rainwater drainage system. In terms of structure design, connection mode and so on, new breakthrough is made, which is more reasonable, better performance and easier to install than the structure of the normal high-rise rainwater drainage system. One kind of energy absorber used for building drainage system (patent no. : ZL201220548025.1) with inverted "V" mode cavity structure design, has more obvious effects of deceleration and energy reduction, so that the safety performance of the whole system is greatly improved.

The perfect combination of pressurized rain water pipe and fittings has further solved high-rise problems and meet the needs of the market to the full extent.
