Color Aluminum water system is the most common water system, but also people choose more, this is because color aluminum water system weather resistance is strong, design and installation is simple, its color rich and so on. There are two reasons why the color aluminum drop system is so popular. 1. The color aluminum drop system has many colors to choose from, which can be matched according to the color of the EAVES, waist line and Exterior Wall of the House Much better than the drab colors of the past, combining traditional architecture with modern art. 2. The surface of the metal aluminum will form a layer of oxide film invisible to the naked eye, so that the aluminum will not be oxidized again, thus the self-protection effect has a high corrosion resistance; secondly, the surface of the aluminum alloy is covered with colored polyester coating, color stability, moreover, the system of Aluminum Alloy Coefficient of thermal expansion and cement base is quite close to each other, avoiding the phenomenon of growth and cracks after the use of color aluminum falling water system, which results in water leakage; moreover, the temperature resistance performance is also particularly good So it can be used whether it's in a very cold area or a very hot place.
