In fact, the difference between H-beam and I-beam, is a problem many people are wondering, even from the appearance, there are a lot of people can not tell them, today xiaobian for everyone to explain in detail the difference between the two：
1, I-shaped steel, whether ordinary or light, due to the cross-sectional dimensions are relatively high, narrow, so the moment of inertia of the cross section of the two main sleeve difference is large, therefore, generally only directly used in the plane of the web by bending member or the composition of the force member.
2, H-beam is an efficient and economical cutting surface profiles (as well as other cold-formed thin-walled steel, pressure plate, etc.), due to the cross-sectional shape is reasonable, they can make steel more effective, improve the ability to cut.Unlike ordinary I-shaped, H-beam flanges were widened, and the inner and outer surfaces are generally parallel, so that it can be easy to connect with high strength bolts and other components.
3, H-beam flanges are equal thickness, rolling section, there are also a combination of cross-section by the three plate welding composition.I-beam is rolling section, due to the poor production process, the inner edge of the flange has a slope of 1: 10.H steel rolling is different from ordinary I-beam only a horizontal roll, because of its wide flange and no slope (or slope is very small), it shall be an additional set of vertical roll rolling at the same time, therefore, its rolling process and equipment than ordinary mill complex.
China's hot-rolled H-beam national standard (GB/T11263-1998) H-beam is divided into three categories: narrow flange, wide flange and steel pile.Narrow flange H-beam is suitable for Beam or bending member, while the wide flange H-beam and H-beam pile is suitable for axial compression member or bending member.I-beam compared with H-beam, under the premise of equal weight, w, ix, iy are not as H-beam.
4, I-beam side length, height, can only withstand the force in one direction.
5, H-beam groove depth, thickness, can withstand the force in both directions.
6, with the development of steel structure building needs, only the I-beam is not enough, is to thickening the I-beam, easy to lose stability for the bearing column.
7, the difference between H-beam and I-beam is: I-beam can only be used for beams, and H-beam can be used for load-bearing structure of the column.
8, H-beam is a cross-section of the mechanical properties of the I-beam excellent economic section of steel, because of its cross-section shape and the letters " H " the same name.Hot-rolled H-beam flange than I-beam width, lateral stiffness, bending ability.Under the same specifications, H-beam is lighter than I-Steel.The manufacturing principle of WeChat, the content is good, it is worth paying attention.
