All the panels made with the pre-painted metal materials mentioned above are supplied upon request with a protective polyethylene adhesive film to prevent damage to the painted layer. If the material is supplied without a protective film, GreenPan is not responsible for any damage on the painting. The protective film must be completely removed during the panel installation and, in any case, within a maximum of thirty days from the delivery of the materials. The panels, still covered by the protective film, must not be exposed to direct sunlight for long periods of time.
