Why I section beam is preferred for heavy loading?

First of all we use I Suction beam Preferred for heavy Loading,because the load will balance

Why I-section beam is preferred for heavy loading?Cross sectional shape I, giving many benefits. It is very good for giving stiffness (less deformation on loading) and to withstand higher bending moments (as a result of heavy loading) on comparison with other cross-sectional shapes of same area. Also, it is very easy to manufacture. Itwill have more moment of inertia.
