How can I distinguish I-beam from H?
The I-beam section is well pressed and resistant to pulling, but the section size is too narrow to resist torsion. H steel is vice versa, so both have advantages and disadvantages.
H section steel is a kind of economical section high efficiency profile with more optimized sectional area distribution and stronger weight ratio. It is named after the English letter "H". This makes the welding of H steel more simple than that of I-beam, the mechanical performance of unit weight is better, and it can save a great deal of material and construction time.
H steel is widely used in steel structure construction. It has many differences comparing with i-beam.1) the flange, the inner edge of the flange has no inclination, parallel to the upper and lower surfaces.2) the outer two sides of H steel are not inclined, and they are straight.3) the section characteristics of H steel are obviously superior to those of traditional I-beam, channel steel and angle steel.
