PVDF Prepainted Aluminium Stripe For Exterior Blinds

This polyester-coated aluminium creates a uniform surface due to the high level of production control. It minimizes thicker painted areas at edges and corners or the "orange peel" texture typically associated with powder coatings. PE coatings are a more cost-effective option than PVDF coatings, but are less durable.
This energy-efficient coating technology is baked at low temperatures, making it ideal for both interior and exterior applications. Additionally, it allows for easy coating of large panels, curves, and complex shapes.
