Mount tripod Building Material Co., Ltd. production of "Ward" the water system, the water system, double-wall, PVC water system, rain gutters, gutters, gutters, gutter, pipe, rainwater pipes, PVC, mesh leaf block, curved water bucket , skis, gutters hanging connector, gutter covers, gutter card connector, gutters lock Bi, a gutter sun angle, overcast angle gutters, rain gutters hanging connectors, rain gutters card connector, Bi rain gutters lock, a water bucket, rainwater pipe, rainwater pipe locator, rainwater pipes interface, a rainwater pipe ramp tee, rainwater drainage, a rainwater pipe straight tee, rainwater pipe adapter, rainwater diverter pipe. Ward gutters should match the size and type of storm sewer gutter type catchy standard size 5.5 inches of rain pipe Cailv K-type 130mm 80mm × 50 mm square tube Cailv 6 inches K-type 147mm 80mm × 60mm square tube Cailv 6.5 inches U type 177mm 75mm / 90mm round tubes Cailv 7 inches K-type 168mm 101mm × 76 mm square aluminum Mount Ding "Ward" Cailv drowning shape with North America's most popular K-type hyperbolic design, the use of corrugated rectangular downspouts design; while metal texture to your building facade new visual expression. Safe stylish and elegant, is the North American residential classic configuration. Superior weather resistance: the surface will form a layer of aluminum oxide film is less visually supported, so that no aluminum oxide, this self-protective aluminum with high corrosion resistance. While aluminum substrate surface covered with colored polyester coating, it can be cold-resistant, 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 proportion of aluminum alloy, aluminum is 2.7, relatively light force object, more significantly enhances the security forces 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 metallic aluminum will form invisible oxide film. Cailv polyester coating surface, can ensure it remains beautiful qualities in cold temperature, acid rain, salt corrosion and other harsh and changeable weather conditions. Due to the low proportion of magnesium alloy , with metal hooks, so gutter force safe, reliable, easy to learn and easy to install. can be recycled, in line with the requirements of the national green building. 15mm diameter falling impact test quality 500 gram ball from 500mm height. No peeling phenomenon bending test at room temperature slowly by a hand press at 180 ° bending test. No peeling No cracking salt corrosion experiments were cross-cut with a cutter to just touch the aluminum plate until, at 35 degrees / C conditions, 5% 360 hours salt spray solution. rust trace the spread of no more than 2mm acid erosion experiment 10% of HCL from the incision, CHCOOH, H2SO4 experiment 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, consistent color
