Exceptional long span element for industrial roofing

Novatec srl, 41013 Castelfranco Emilia (MO), Italy


Ondal® is the latest and highly advanced precast system for industrial use patented under the surname Dal Lago. The system has been launched on the market in its first version 1989 and since then it has been subject to a constant evolution up to the patent of 2012 (Ondal 12®), characterised by several functional innovations. It is estimated that more than 16 million square metres of precast buildings have been made with the Ondal system from 1989 mainly in Italy, France and Spain, but also in Latin America and Northern Africa. The structur- al optimisation of the system brought to the attainment of an average m3 of concrete over m2 of the building ratio as low as 0.12. Lightness, architectural appeal and economy are among the factors that allowed its success. The system is used to build large structures completely precast with wing-shaped pre-stressed slab members distanced by shells, pre-stressed beams, columns and foundation footings in reinforced concrete. It is cladded with precast concrete panels. Fig. 1 shows the components of the system. Dry mechanical connections are used for all members, allowing for a high speed of assemblage.
