Steel H beam have a thicker web because the web is more likely to buckle under axial compression than under flexure. H sections also have thicker flanges as they too may buckle under axial compression. H sections tend to be very square, their width is similar to their height. This is so that their I values in both directions are similar.
Steel I beam,as its name suggests, is a kind of "I" shaped cross-section steel, the inner surface of the upper and lower flanges has the inclination, generally 1: 6, so that the outer flange is thin and the inner is thick, resulting in steel I beam’s two main plane section properties have a huge the application,it is hard to show the strength properties of steel
An H-beam has a thicker center web, which means it is often stronger.
An I-beam often has a thinner center web, which means it is often not able to take as much force as a H-beam.
An H-beam may be built up, meaning it can be built up to any size or height.
An I-beam may only be built up as much as the manufacturers milling equipment allows.
The H-beam is often a lot heavier than the I-beam, which means it can take more force.
The I-beam is often lighter, but this is desirable in some buildings where weight and force on a wall may pose a structural issue.
The manufacture process means that H-beams can be used for spans up to 330 feet.
An I-beam may be used for spans of between 33 and 100 feet. Longer I-beams are not often an option as they are tough to manufacture.
The H-beam has a bevel where three pieces of metal come together and look like one piece of metal.
An I-beam is just one piece of metal throughout and is not made by welding or riveting sheets of metal together.
H-beams have top and bottom flanges that stick out further from the web than the flanges on I-beams.
I-beams have top and bottom flanges, and they are shorter and are not as wide as H-beams.
