PREFA - Aluminium Composite Panel
The aluminium composite panel consists of two aluminium sheets which are fusion-bonded to both sides of a polyethylene core. Through the equal measure of chemical bonding and mechanical fastening, this combination is particularly robust. In this way, the aluminium composite panel ensures consistent evenness and stability, even on large-scale surfaces.
