Supply factory direct rainwater pipe water system Which is better: Corus new water system in the water break through the traditional architecture on the basis of the gutter, innovative thinking concept, design a very contemporary colors, smooth lines of the new water system. Enhance the overall effect of the building, so that adds a unique flavor architecture. To meet the desire of our customers to innovate; a variety of colors white, gray, brown, so that our customers to choose the color, and the building's exterior and roof more with each other, full of vitality, to make the building more integrated with the natural environment. Product Overview metal water system water system in North America and Europe accounted for 80% of the entire market of the water, the water system of metal materials including galvanized iron, colored aluminum, zinc alloy and high-end brass; which Cailv the water system Its color effect, excellent weather resistance and relative economy accounts for more than 90% of the metal water system market. The market for our common domestic cement pouring gutter and PVC gutter before, but these products because of their own shortcomings, such as cement gutter because the geological changes over time can lead to leakage from the crack, PVC gutters because it is plastic material, poor UV resistance, thermal expansion and contraction changes, leading to short life shortcomings. It is against this background that we introduce in Europe and America popular metal drowning technology, combined with domestic characteristics, launched Cailv gutter. Aluminum oxide film formed on the surface layer of invisible, no aluminum oxide, the self-protection of the aluminum with high corrosion resistance; secondly aluminum substrate surface covered with colored polyester coating, color stability ; coefficient of thermal expansion coefficient and cement grassroots aluminum close third (PVC and cement grassroots larger difference in thermal expansion coefficient), and not in Cailv the water system after use, causing risen and crack, resulting in leakage; while aluminum at a temperature of between -45 ° to 260 ° C, strength, performance unchanged; therefore cold areas such as the Northeast region in China.
