Corus gutter water system performance, affordable. Compared with the traditional system of PVC products. Performance, fewer parts, construction and more convenient. The new water system in the water to break through the traditional architecture, based on in-depth study abroad roof drainage, and developed the combination of domestic PVC drainage system of the building, which has the following characteristics: 1, Corus water system uses double-walled large arc design , allowing both functional and decorative effect of drainage, enriching the overall effect of the building. 2, Corus water system uses double-walled gutters and use imported impact additives, making both strong and flexible, component, node design is reasonable, taking into account both the sealing performance of the gutter, but also give full consideration to facilitate the construction and does not there is water in the phenomenon. 3, Corus water system using ethylene polymer material, a unique formula, with good UV resistance, excellent weather resistance, no oxidation, corrosion, does not pollute the strong side. 4, Corus fell into complete parts and accessories, using organized drainage, green lawn has a good protective effect, avoid drowning freedom sludge spill wall impact wall effect, rainwater pipe adapters, curved water bucket and other accessories to solve the balcony, floor drain and air-conditioning condensate drain unified position of organized water and other characteristics, in order to ensure that the system is more perfect to meet the requirements of domestic architecture. Lateral drains beneath the eaves trough, for receiving the roof rainwater, and then lead to the ground by the standpipe Building Materials Co., Ltd. Hangzhou Ruichen
