I-beam, also known as steel beam (English name universal Beam), is a long steel with the section of the I-shaped. I-section steel is divided into hot rolIed I-beam  and lightweight  I-beam
I-beam is mainly divided into ordinary I-beam, light I-beam, low alloy light I-beam .

Angle steel,commonly known as angle iron ,is a carbon structural steel used in construction. It is a long strip of steel with two sides perpendicular to each other. It is a  profile steel with  simple section . Angle steel is divided into equal  Angle steel and unequal  Angle steel.

H-beam is a kind of Economic section steel, which  sectional area distribution is more optimized, the  ratio of  strength to weight is more reasonable, Mechanical properties of section is more better.It is developed from the I-section steel optimization of a better section mechanical properties of the economic section steel, because its section is same as  the English letter "H" ,so be named as H-Beam. Because the various  part of H-beam is arranged at right angles, H-beam has the advantages of strong bending resistance, simple construction, cost saving and light structural weight in all directions, so it has been widely used.
