Corus metal water system materials including galvanized iron (for arid regions), colored aluminum, zinc alloy and high-end brass; beautiful colors: Cailv the water system to provide a variety of colors for designers and developers of products , and the color of the roof construction, waist, wall, etc. matched. In addition to the current six standard colors, but also provides the designer to specify the color that, according to designer color requirements, provide color. Unique semicircle 6.5 inches (H) type water system: It is suitable for hard tiles and large size S M Watts, more harmonious and now popular with Southern California architectural style. Simultaneously on multiple layers of gardens, to better reflect the semicircle matching 6.5 inches (H) type of water system on the classical style and size. Beautiful shape: Company Cailv the water system in North America's most popular form factors of 51/8 inch K type hyperbolic appearance, 6.5 inches Southern California Spanish architecture semicircle coordinated use of (H) type two exterior design gutters, downspouts K is used corrugated rectangular design, 3 inches and 4 inches tube tube design. Corus metal texture of the water system of metal to bring your building facade and simple visual experience. Safe stylish and elegant, classic European and American homes configuration. Look as new: invisible layer of oxide film formed on the surface of aluminum, aluminum oxide, no, this self-protective aluminum with high corrosion resistance; secondly aluminum substrate surface covered with colored polyester coating layer, color stability; coefficient of thermal expansion coefficient and cement grassroots aluminum close third (PVC and cement grassroots larger thermal expansion coefficient difference), and not in Cailv the water system after use, causing cracks and risen, resulting in leakage; at the same time Aluminum alloy at temperatures between -45 ° to 260 ° C, the strength, the same performance; it can in cold regions, intense sun areas, large temperature resistance and other harsh climates varied use, to ensure lasting as new. Security: the proportion of metal aluminum is 2.7, the entire water system is relatively light, a significant increase in the security forces. Green: recyclable, residual value is about 50% Cailv the water system is an international universal common downspout system, water system advantages Cailv beautiful and decorative effect of a natural harmony) metallic bring a strong performance for the construction force. 2) different color choices to the designer's imagination in a vast space.
