The composite panel is composed of two aluminum sheets joined by a core of thermoplastic resins (polyethylene). On the outside, it is composed of an outer layer of 5005 H42/H44 aluminum alloy lacquered with a three-layer PvdF (fluorinated polyvinyl) paint that offers high resistance to corrosion and aging.

This combination of materials gives the composite panel excellent mechanical properties: high impact resistance, high rigidity and low weight.
