  • About us :

    Roofing fan using joists and blocks is actually a combination of two types of prefabricated and in-place concrete. In Iran, the use of joists and blocks on the roof has expanded dramatically in recent years due to the practical evolution of building materials, and the use of this system in conventional buildings is very common. Joinery and block ceilings are divided into two categories: concrete roof joists and open joist steel ceilings, due to the need for no molding and the formation of a rigid diaphragm that integrates the building structure. Resistant to earthquake forces, widely used in buildings.
