Color aluminum square downspout manufacturer finished gutter price type color aluminum downspout system features:
The metal texture brings strong expressive power to the building. The choice of different colors gives designers a broad space for imagination. The color matching with the building itself shows the natural atmosphere of the building. Colored aluminum will not be oxidized because an oxide film invisible to the naked eye will form on the surface of metallic aluminum. The polyester coating on the surface of colored aluminum can ensure that it maintains its gorgeous true color under severe and changeable climate conditions such as severe cold and high temperatures, acid rain and salt corrosion. Due to the low specific gravity of aluminum-magnesium alloy, coupled with the metal hook, the gutter is safe and reliable, and the installation is easy and convenient. It can be recycled and meets the national green building requirements.
Impact test: A steel ball with a diameter and a mass of grams is dropped from a high place without peeling off.
Bending test:
Use a manual press to slowly conduct a bending test at room temperature. There is no peeling or cracking.
Salt corrosion resistance test:
Use a cutter to cross-cut until it just touches the aluminum plate. Spray salt solution for 3 hours at 3 degrees/condition, and the rust will not spread beyond the cut.
Acid corrosion resistance test:
There is no change in the surface after the test.
Temperature experiment:
The performance is stable and the color is consistent under the conditions of arctic cold and sub-zero temperatures and equatorial high temperatures.
