Ruichen seven characteristics of building materials Cailv the water system: a metal water system occupied more than eighty percent of the North American market, the metal material of the water system include galvanized iron (for arid regions), color aluminum, zinc Copper alloy and high-end materials. Cailv the water system which according to his color effects excellent weather resistance and relative economic line accounted for more than ninety percent of the metal water system market. Second, the beautiful colors: Cailv the water system designers and product developers to provide a variety of colors, and the roof of the building, first, facades and other colors matched, except now we are five standard color options other than further provide customized services designer. Third, the unique 6.5-inch circular water system: It is suitable for hard tiles and large size s m watts, more harmonious way to show now and Mediterranean in the west, while the layers of gardens, to better reflect Match classical style and size 6.5-inch round on the water system.

Fifth, look as new: metal color aluminum surface will form an invisible layer of oxide film is not oxidized aluminum, this self-protective aluminum with high corrosion resistance, followed by secondary aluminum substrate surface colored polyester layer, color stability, thermal expansion coefficient and the coefficients of the third aluminum cement base close, not after Cailv the water system, resulting in expansion and crack, resulting in leakage, colleagues aluminum at high temperatures to -45 ° between 260 °, the strength properties of the same, and therefore can be used in cold and high temperature zone, the temperature difference between day and night, not longer influence to ensure lasting as new. Sixth, security: the proportion of metal aluminum 2.7, the entire water system is lighter, greatly improve the security force. Seven green: Aluminum can be recycled, it will not cause waste of resources.
