Coated Aluminum Slats For Venetian Blinds

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.

When choosing coated aluminum slats for venetian blinds, factors such as material, coating, color, and size need to be considered.
