How Much Do You Know About I-beam?
I-beam is a strip of steel with an I-shaped section.
I-beam whether ordinary or light, because the section size are relatively high and narrow, so the moment of inertia of section two of the spindle is larger, so it 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-beam is a kind of economical and economical 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. The size of the series is reasonable, the model is complete, easy to design and use.
