Compocel®ALF

The sandwich panel COMPOCEL ALF is a panel with aluminium skins and PET or PVC core

COMPOCEL ALF is a composite sandwich panel with skins in aluminium and core in PET or PVC. It is typically used in vans and in the building sector. It can be constructed with the necessary inserts and edges, according to customer specifications.

 

 

A -  SKINS OF ALUMINIUM
Thickness mm: 0,5 - 0,8 - 1 (standard) 
 
B - STRUCTURAL ADHESIVE
  
C - CORE IN FOAM

 

The sandwich panel COMPOCEL ALF is available on request with:

  • skins in different colours
  • different types and thicknesses of foam

IMPORTANT

To allow us to offer you a 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.
