Overview of metal falling water system products:
Metal falling water systems account for more than % of the entire falling water product market in North America and Europe. The materials of metal falling water systems mainly include galvanized iron plates, colored aluminum alloys, zinc alloys and high-end Among the copper materials, the colored aluminum drain system accounts for more than % of the metal drain system market due to its color effect, excellent weather resistance and relative economy.
In the past, cement-cast gutters and gutters were commonly seen on the market in our country. However, these products had their own defects. For example, cement gutters would crack due to geological changes over time, leading to leakage. It is made of plastic, has poor UV resistance, and undergoes large changes in thermal expansion and contraction, resulting in short service life.
It is against this background that Corus introduced the metal water-falling technology popular in Europe and the United States, and combined it with domestic characteristics to launch color aluminum gutters. A layer of oxide film invisible to the naked eye will form on the surface of metallic aluminum, preventing the aluminum from oxidizing. This self-protection makes aluminum highly resistant to corrosion. Secondly, the surface of the aluminum alloy substrate is covered with a colored polyester coating, which makes the color stable. The thermal expansion coefficient of the three-aluminum alloy is close to that of the cement base layer (the difference between the thermal expansion coefficient of the cement base layer and the cement base layer is large). It will not cause swelling and cracks after the use of the colored aluminum water drainage system, resulting in water leakage. At the same time, the aluminum alloy is between the temperature and The strength and performance remain unchanged, so it can be used in harsh and changeable climates such as severe cold areas such as Northeast China, strong sunlight such as Southern China, and large temperature differences between day and night such as Xinjiang, China, ensuring that it will last as long as new.
Our company’s metal water-falling system products are also among the few domestic water-falling system products that have been corroded by artificial gas salt spray without any corrosion pitting. Because of the support and trust of our customers, we believe that Corus will become the most professional expert in comprehensive solutions to falling water systems in China and the leader in the most cost-effective roofing system products.
