What are the uses of I-beam and H steel?
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 can be easily connected by high strength spiral bolts and other components. Its size constitutes a reasonable series, complete model, easy to design and use.
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.
HW HM HN H is a general term for H steel, H is welded, and HW HM HN is hot rolledHW is a H type steel flange height and width substantially equal; mainly used for reinforced concrete frame column steel column, also known as rigid steel column; column is mainly used in steel structure
The flange of the I-beam is variable cross section, the thickness of the web is thin and the outside is thin. The flange of H section steel is equal section
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.
