Now I introduced a color aluminum 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; it can in the cold regions such as northeast China, such as the sun and intense in southern China, such as resistance to large temperature under changing China's Xinjiang and other inclement weather use; ensure lasting as new. My company is currently one of the few metals fell into the water through artificial gas spray corrosion pitting phenomenon without any water system products. Because of the support and trust of our customers, we believe Ruichen building materials must be able to become the most professional of the water system comprehensive solution experts, the highest price of the roofing system products leader. Second, Cailv the water system, also known as the water system Introduction roof drainage system, including finished gutter, downspout and related components. Its role is to effectively roof rainwater collection and organized the rational and efficient discharge of rainwater from the building, resulting in the completion of roof drainage, while well protected facades and foundations of houses, try to extend the life of the Swiss building Morning water system has two main parts: the gutter and accessories (including: cover around, inside and outside corners, gutter hanging pieces, skis, gear leaves the network, etc.), downspout and accessories (including: elbow, pipe card , strainer, tees, etc.) Third, Cailv the water system Features European and American fashion metal drowning is characterized by a variety of materials offers a variety of series of metal fell into the water system, providing value element of real estate developers, designers offer new Design ideas for your home bring with a metallic finish, environmental protection, energy saving, gorgeous, most expensive water system.
