Precast reinforced concrete roof
Prefabricated reinforced concrete roofing
The ONDAL + type was created to extend the possibility of using the ONDAL system. Without prejudice to the variability of the interaxis of the tiles between 5. 00 m and 7. 50 m, the length of the tile can cover up to a center distance of 32. 00 m from pillar to pillar.
The technical and performance characteristics of this cover are similar to those of ONDAL, as well as the production technology of the prefabricated components and of completion. Studied, designed and produced complete with various types of waterproofing in the factory, it produces reinforced concrete, flat and shed roofs. The two types can also be present on the same coverage. The natural lighting can, therefore, be obtained with the flat structure or through a shed frame, particularly designed to ensure both maximum insulation and maximum illumination.
The modularity of the elements makes it possible to easily change the shape of the roof over time if new needs arise. The entire roof, in every detail, offers the highest parameters about static, lighting, insulating, fire resistance and fire reaction.
Particular importance is given to the possibility of designing structural meshes of large pillars: 25. 00 m x 25. 00 m and, in particular cases, even larger ones.
The macro-advantages of this solution are evident, in particular the following:
- Maximum usability of the internal surface of buildings, especially large ones;
- Significant cost savings for the construction of substructures
