The composite panel consists of two aluminium sheets joined by a core of thermoplastic resins (polyethylene). Externally, it is composed of an outer layer of 5005 H42/H44 aluminium alloy lacquered with three-layer PvdF (polyvinyl fluoride) paint, which offers high resistance to corrosion and ageing.

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

La barandilla o baranda es un tipo de parapeto formado de balaustres, que constituye un elemento de protección para balcones, escaleras, puentes u otros elementos similares.

La barandilla sigue el perímetro de la estructura con una altura constante, permitiendo apoyarse gracias a su travesaño superior, llamado pasamano o pasamanos.
