1. The side length of the I-steel is small, the height is large, and it can only withstand the force in a single direction.
2. The H-shaped steel groove is deep, the thickness is large, and it can withstand the force in two directions.
3. With the development needs of steel structure buildings, only I-steel is not available, that is, thickening I-steel for load-bearing columns is easy to lose stability.
4. I-beams can only be used for beams, while H-beams can be used for the bearing columns of the structure.
5.H section steel is a kind of economic section steel with better mechanical properties than I-steel, because the shape of its section is the same as the English letter "H". The flange of hot-rolled H-beam steel is wider than that of I-beam steel, the lateral stiffness is larger and the bending resistance is stronger. Under the same specifications, H-beam steel has lighter lineweight than I-beam steel.
6. The I-beam flange is thick by the web and thin on the outside; The flange of H-shaped steel is equal face.
7. HW, HM, HN is the common name of H-beam steel, H-beam steel is welded; HW, HM and HN are hot rolled.
