SANDWICH PANEL COMPOCEL AL AND COMPOCEL AL FR

COMPOCEL® AL​ is a sandwich panel with a core in aluminium honeycomb bonded to two skins of aluminium. It offers superior mechanical properties and excellent fire ratings. Its certified version, COMPOCEL AL FR has passed the most stringent tests of European Regulation in shipbuilding, building and railway sectors.

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.
