Coil coating, also known as pre-painting, is a continuous roll-coating process where aluminum coil passes through a multi-stage production line before being cut, formed or fabricated. The process begins with chemical pre-treatment for surface cleaning and conversion coating, followed by primer application, oven curing, top coat application and final curing.
Ballesta does not operate an in-house coil coating line. Instead, we source pre-painted aluminum coils from a network of established, ISO-certified finishing partners with decades of specialized experience. This partnership model allows us to offer a wider range of coating chemistries and specifications than any single production line could provide, while maintaining strict quality control through incoming inspection and batch traceability.
Pre-painted aluminum is the preferred choice for large-scale architectural projects where color consistency across thousands of square meters is critical. Because the coating is applied to flat coil before roll-forming or bending, the finish remains intact throughout fabrication, with no cut edges or handling damage typical of post-painted panels. Our supply chain model ensures you get the right coating chemistry for your specific project requirements, not just what one line can produce.
