What is the difference between I-beam and H steel?
The flange of the I-beam is changed to wear, the thickness of the web is thin and the outer part is thin; the flange of H steel is equal to the wearing surface.I-steel whether ordinary or light, because the section size are relatively high and narrow, so the moment of inertia of the main sections of the two sleeve is large, therefore, generally only can be directly used in the web plane bending member or the composition of lattice stress components. It is not suitable for the axial compression member or the bent member perpendicular to the web plane, which has great limitations in its application.H section steel is a kind of economical and economical cutting surface profile (other cold bending thin wall steel, pressed steel plate, etc.). Because of the reasonable cross-section shape, they can make steel more effective and improve the bearing capacity. Unlike ordinary I-beam, the flange of H steel is widened, and the inner and outer surfaces are usually parallel so that it is easy to connect with high strength bolts and other components. Its size constitutes a reasonable series, complete model, easy to design and use. (in addition to crane girders)
H steel is a kind of economical section steel with better mechanical properties than I-beam. Its shape is named after its English letter "H". The flange of hot rolled H steel is wider than that of I-beam, big lateral rigidity and strong bending resistance. Under the same specifications, H steel is lighter than i-beam.
I-beam can only be used for cross beams, and H steel can be used for structural load-bearing columns
The length of the I-beam is small and the height is big. It can only bear the force in one direction. H steel is deep in groove and big in thickness and can bear two directions of force.
