Aluminum alloy gutter sink

 

Whether the self built villa meets this situation: in rainstorm days, the rain splashes along the roof, the wall is washed full of water stains, and has become moldy and cracked for a long time; The accumulated water on the roof cannot be drained out and slowly seeps into the roof, making maintenance both expensive and time-consuming; The selected gutter has aged and deformed after only a few years of use, which not only affects its appearance but also needs to be replaced again……

 

In fact, the key to solving these troubles is to choose the right reliable gutter sink! At present, there are various materials on the market, including galvanized sheet, copper plate, color coated aluminum plate, stainless steel plate, PVC, etc. Among them, the gutter sink made of color coated aluminum coil has become the first choice for more and more high-end residences with its "hard power"!

 

 

Hard Power.ONE

Lightweight and high-strength, flexible on-site processing, easy to install

One of the most prominent advantages of color coated aluminum coils is their lightness and strength. Aluminum alloy itself has a lightweight texture, much lighter than galvanized or stainless steel plates. It is easy to transport and only requires simple drilling and fixing during installation, greatly saving labor and construction time. It perfectly solves the pain points of traditional materials that are "difficult to install heavy and not resistant to manufacturing light".


More practically, its lightweight characteristics allow it to be quickly pressed and molded, and can be flexibly adjusted according to the size specifications of the villa roof. Even irregular eaves shapes can be processed and cut on site without the need for pre customization and waiting, and the construction efficiency can be directly maximized.


At the same time, its strength is unambiguous. Series 1, 3 and 5 alloy base materials can be used, which can easily withstand the impact of rainstorm, ice and snow without fear of deformation caused by water pressure. It is especially suitable for outdoor scenes such as roofs, giving consideration to convenience and durability.

Waterproof, corrosion-resistant, weather resistant, outdoor durability for 20 years+

 

Litong color coated aluminum coils are made using roller coating technology. The weather resistant paint will form a weather resistant protective film on the surface of the aluminum coil, and the three roller two coating process will evenly adhere to the surface of the aluminum coil like car paint, with excellent adhesion.


Weather resistant color coated aluminum coils can effectively isolate adverse effects such as ultraviolet radiation, acid rain, salt corrosion, etc., eliminating rust and water leakage problems from the root. Even if exposed to sunlight and rain for a long time, they will not become brittle, crack, or fade. The outdoor service life can reach more than 20 years without frequent maintenance and replacement.
