Mega Prefab's hollowcore slab (or dalle alvéolée in french) is a precast prestressed concrete slab used in all types of buildings.
more economical,long spans at thin sections,no propping, faster construction are some of it's advantages over traditional systems.
In the industry of prestressed structures, hollow core slabs represent the most advanced product. It is a constructive element whose production is highly industrialized and completely automated with the latest world’s technology.
The slabs have longitudinal cores running through them, the primary purpose of the cores being to decrease the weight, and material within the floor, yet maintain maximal strength. To further increase the strength, the slabs are reinforced with steel strand, running longitudinally.
Currently we offer slabs depths ranging from 150 to 300 mm, for computed spans from 4 to 16 meters and live loads from 0.2 to 4 Tons/m2, and fire resistance up to three hours. Depending on the project requirements, in particular span and loading performance, a particular slab depth is chosen. Such variety fulfills the needs of the clients.
