U-shaped Steel Mine Supports is an economical section steel with excellent mechanical properties compared with I-beams. It is named after the shape of the section is the same as the English letter "U". U-shaped Steel Mine Supports are high-efficiency economical sections (others are cold-formed thin-walled steel, profiled steel, etc.), and because of their reasonable cross-sectional shape, they enable Steel Mine Supports to perform more efficiently and improve their ability to undertake. Unlike the normal I-shaped type, the flange of the U-shaped Steel Mine Supports is widened, and the inner and outer surfaces are usually parallel, which facilitates the connection with high-strength bolts and other components. Its size constitutes a reasonable series, the model is complete, easy to design and use. (except for I-beams for crane beams)
I-beam is also called steel beam and is a long strip of steel with a cross-section of I-shaped. I-shaped steel, whether it is ordinary or light, because the cross-sectional dimensions are relatively high and narrow, the difference between the two main sleeves has a large difference in the moment of inertia. Therefore, it can only be used directly in the plane of the web. The bent members or they are combined into a lattice-type force member. It is not suitable for the axial compression member or the member that is curved perpendicular to the plane of the web, which makes it have a large limitation in the application range.
