Sandwich Panels, Aluminum and Thermoplastics honeycombs and Foams
COMPOCEL® AL FR offers superior mechanical properties and excellent fire ratings. COMPOCEL® AL FR has passed the most stringent tests of European Regulation as far as fire reaction is concerned in shipbuilding, building and railway sectors.
Our panels are produced according to the needs of our clients, who determine size and other panel characteristics.
Panel for false ceilings and ventilated facades, in class A2, therefore non-combustible. Thanks to special assembly techniques, COMPOCEL AL ® FR A2 meets the requirements of the UNI-EN 13501-1 standard.
Mod B. and D according to the IMO MED FTP CODE 2010,
HL3 according to the UNI EN 45545-2 standard for R1, R2, R10 applications.
These precision processes are performed by numerical control machines (CNC).
To obtain special shapes and processes, it is necessary to provide a DWG or DXF format drawing in advance.
The COMPOCEL AL FR Sandwich Panel has been certified with different types of powder or liquid coatings to adapt to the various stylistic, aesthetic and environmental needs.The skin material can be painted in different RAL colours. The external layers are available in different thicknesses and coatings, anodised or with primer.
User manual indicates the conditions in which the material must be stored and preserved in an optimal manner. Here are some of the most important factors that influence the conservation of the panel: storage temperature, handling, exposure to light and atmospheric agents.
Particular attention must be paid in the presence of protective films that could be difficult to remove when subjected to atmospheric agents or following prolonged storage times.
The panel can be easily cleaned and degreased, however the use of acidic substances or with abrasive components is not recommended as they could compromise its aesthetic qualities.
To allow us to offer youna panel with particular finishes or colors without minimal pigment variations, it is recommended to place an overall order , so that we can plan the production with the rolling mills that will carry out the painting of the sheets in a batch.
The COMPOCEL AL FR panel is 95% recyclable as it is composed of 95% aluminum, which can be melted and reused several times.
The COMPOCEL AL FR panel is normally purchased by all those customers who need lightness combined with excellent reaction to fire performances. The new terminal of the Charles de Gaulle airport in Paris, the new airport of Athens the tower of the Turkish central bank (work in progress) eg. are built with COMPOCEL AL FR panels.
