The flexibility:The depth of this beam section can be designed according to the required floor depth.Typical proportion of this composite beam is 190 to 350mm for a span of 6 to 12m The inherent fire protection:The incorporation of the upper flange plates and cores of the beams in the thickness of the concrete slab provides structural protection which meet most requirements. Construction time:The beam can be used with pre-cast units and metal deck floors which eliminates the time spent for concrete hardening in the traditional beam constructions. Economic and operational:High reduction of costs can be achieved by less amount of steel used and the saving due to the stud shear connectors has to be highlighted.Another important factor is of the total life-cycle cost
