October 30, 2023

Coated aluminum slats for venetian blinds are usually made by coating a layer of PVDF fluorocarbon coating or PE polyester coating on the surface of the aluminum alloy substrate. These coatings give the aluminum slats excellent weather resistance, corrosion resistance and self-cleaning performance, allowing them to resist erosion from various chemicals and remain unfaded when used outdoors for a long time. In addition, coated aluminum slats also have excellent decorative and processing performance, which can meet various appearance requirements and processing needs. They usually have a beautiful appearance and light weight, making them easy to install and use.
