Hangzhou water system, square downspouts, finished gutters, drainage system

Hangzhou drowning Building Materials Co. Founded in 2009, the company is located in Yuhang Industrial Zone, it is a research and development, production and sales in one of the production units. Companies specializing in the production of finished Gutter, water system, square rainwater pipes, products Cailv of the cases, PVC series of cases, the resin of the cases, the company's products won the national quality system, testing and certification, patent certificate, innovative perfection, seamlessly storm sewer The technology used is the first to fill the gaps in the industry, with many years of industry experience to make the company's products in the industry has always been a leader. We always adhere to the "scientific management, technological innovation, service first" quality policy and business philosophy to market demand-oriented, establish clear values, in order to serve partners and customers, the creation of the partners and customers gbm a model of cooperation. Building materials fell into the water system characteristics Cailv. Cailv the water system to provide a variety of colors for designers and developers of products to be compatible with the building's eaves, roofs, facades and other colors. Beautiful appearance: Cailv the water system of shape with North America's most popular K-type hyperbolic appearance and 51/8 inch gutter design, downspouts is used corrugated rectangular design; at the same time the metal texture to your building a completely new facade visual expression. Safe and elegant fashion, is the North American residential classic configuration. Superior weather resistance: the surface will form a layer of aluminum oxide film can not hold the naked eye, no aluminum oxide, this self-protection aluminum with high corrosion resistance. While aluminum substrate surface covered with colored polyester coating, it can be resistant to cold, high temperature; in acid rain, salt corrosion and other harsh variable climate remains stable color, look as new. Greater security "Cailv the water by the specific gravity of aluminum alloy, aluminum is 2.7, relatively light force object, more substantial stingy security force of K-type Cailv the water system features: metallic for the construction bring a strong performance. different color choices to the designer with a broad imagination. and color with the building itself shows the natural atmosphere of the building. Cailv not oxidized, it is because the surface of the metal aluminum will form invisible oxide film coated polyester color aluminum surface, it can ensure it remains beautiful qualities in cold temperature, acid rain, salt corrosion and other harsh changeable weather conditions. Due to the low proportion of aluminum-magnesium alloy , with metal hooks, so gutter force safe, reliable, easy to learn and easy to install. can be recycled, in line with national green building. impact test drop of 15mm diameter by mass of 500 gram steel ball from a height 500mm. No release phenomenon bending test at room temperature slowly by hand press 180 degree bend test. No peeling No cracking Salt eclipse experiment carried out cross-cut with a cutter to just touch the aluminum sheet date, at 35 degrees / C conditions, 5% saline spray 360 hours. rust trace the spread of no more than 2mm acid etch test 10% of HCL from the incision, CHCOOH, H2SO4 test 100 hours Surface temperature experiments no change in the arctic cold of minus 50 degrees and 60 degrees below the equator temperature insolation conditions stable performance [Close] [Print]
