Who We Are

ASSAP is a non-profit Association for the promotion, safeguarding and defence of the hollow core floor and the legitimate interest of associated producers. ASSAP was founded in June 1982 near Parma (Italy) with the partecipation of almost half of the producers then present on the market.


The production of prestressed hollow core slabs take place in works on iron beds (120/150 m in lenghth) on which prestressing wires are positioned and stretched. Casting of concrete is continuous and done with specific machinery.
