Are there any differences between the two prices of I-beam and H steel?
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.
The flanges of Wuxi H steel are of equal thickness, have rolling section, and have a combined section composed of 3 plates welded together. Hua Liang 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. China's hot-rolled H steel GB (GB/T11263-1998) H steel is divided into narrow flange, wide flange and steel pile three categories, its code names are Hz, HK and hu. The narrow flange H steel is suitable for beams or columns, while wide flange h and H steel piles are suitable for axial compression members or bending members. Compared with H steel, the W, IX and iy are better than H steel under equal weight condition.
H section steel 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 can be easily connected with other components by high strength bolts. The size of the series is reasonable, the model is complete, easy to design and use.
