H steel compared with ordinary steel in the end what are the advantages and disadvantages?
The flanges of H steel are all of equal thickness, there is a rolling cross section, and there is a combined section composed of 3 plates welded together. I-beam is a rolling cross section, due to poor production process, flange within the edge of the 1:10 slope. H type steel rolling is different from ordinary I-beam with only one set of horizontal roll, because of its wide flange and no inclination (or inclination is to be very small), a group of vertical roll and roll, therefore, the rolling process and equipment than the conventional mill complex. The maximum rolled H steel produced in China can be 800mm high and can only be welded composite sections.
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)
