Color Coating Aluminium Stripe For Exterior Blinds

Color coating polyester painted 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.

FAQ – Color Coated Aluminium Strips for Exterior Blinds

What are pre-painted aluminium strips mainly used for in outdoor applications?

They are primarily used to manufacture slats and louvres for exterior horizontal blinds, outdoor roller shutters, venetian blind systems and architectural sun shading solutions.

Which coating provides the best durability for exterior blinds – PVDF or polyester?

PVDF coatings deliver superior UV resistance, colour retention and longevity (20+ years) making them ideal for harsh outdoor environments including coastal and high-sun areas.

Can custom colours and wood grain finishes be produced?

Yes – full support for any RAL K5/K7, Pantone reference or custom colour matching, including realistic wood grain and textured effects for aesthetic exterior applications.

What is the typical MOQ for colour coated aluminium coils?

Standard MOQ is 2–5 metric tons per specification; smaller trial quantities may be possible subject to colour and stock availability.

How weather-resistant are these pre-coated aluminium strips?

Extensively tested with 1000-hour QUV, 3-year Florida exposure and salt spray certification, ensuring outstanding performance in marine, tropical and urban climates.
