Ruichen provide North American popular 51/8 inch K type exterior design, excellent weather resistance and chemical stability, look as new. Safety component, green. A substantial increase in the use of metal pieces by the force of security and reliability, to meet wind and snow load, performance and lasting. Building Materials Co., Ltd. Hangzhou Rui Chen has more cities in the domestic development of a broad marketing network, is committed to China universal water system, application and development to make a positive contribution, sought to focus on the water system, but also to achieve "good faith development, focus on the water, excellent quality, extraordinary skill, industry-leading. " 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 area, sun strong regional resistance, large temperature changing climates and other harsh use, to ensure lasting as new. Security: the proportion of metal aluminum is 2.7, the entire water system is relatively light, a substantial increase in security forces. Green: recyclable, residual value is about 50% Cailv the water system is a universal generic downspouts international system, the water system Cailv advantage are beautiful and coordination of natural decorative effect
