The beam is a structural member that shapes like a capital H consist of rolled steel.H section beams are widely used for commercial
and residential buildings due to their strength to weight ratio and superior mechanical properties.
The beam flanges don’t have an inside inclination,making the weding process easy,both flanges have equal thickness and are parallel to each other.
Its cross sections characteristics are better than I beam.and it has better mechanical properties per unit weight that save material and cost.
It is the favored material for platforms,mezzanines and bridges.
