The Aluminium Coil Coating Line is a continuous process used to apply decorative and protective coatings to aluminium coils. This line consists of several stages, each making the aluminium more appealing and resilient.

During this stage, the aluminium passes through a roller, where a layer of primer is evenly applied. “Does it dry right away?” you might wonder.

Now, the fun begins! The aluminium is ready for the color coat.
Various pigments and dyes are mixed to create an array of colors. “Can I choose any color I want?” you ask. Yes! Custom colors can be made to meet specific design requirements.
This stage also uses a roller for application. The coils pass through the color applicators, mimicking the primer application process.
After application, it’s crucial to cure the color coat. “Why do we need this step?” you may question.
