Sandwich Panels, Aluminum and Thermoplastics honeycombs and Foams
COMPOCEL® AL is a sandwich panel with a core in aluminium honeycomb bonded to two skins of aluminium.
The face material can be painted in different RAL colours. The external layers are available in different thicknesses and coatings, anodised or with primer.
Our panels are produced according to the needs of our clients, who determine size and other panel characteristics.
