The joist slab system consist of open web steel joists and concrete covering. The outstanding privilage of the system compared with other systems is the fact that system dose not require any temporary shoring during the construction period and also the steel joists are easy to handle and they are not susceptible to damage during the transportation and finally the bottom surface of the slab is very smooth and uniform which makes it suitable for plastering.

When concrete reaches to 75% of its strenght, then the joists and concrete cover will act as a composite section to support any extra dead and live load imposed on them.

The speed of contruction, relative lightness of slab, the possibility of insulating characteristics of this slab against the temperature and sound are some ot the reasons for popularity of this system.
