I-beam, also known as steel beam (Universal Beam), is a long strip of steel with an I-shaped cross-section. I-beams are divided into ordinary I-beams and light I-beams. It is a section steel with an I-shaped section. Due to high and narrow section size, the inertia moment of the two main axes of the section is quite different. It can only be directly used for bending in the plane of its web member or form it into a lattice-type force-bearing member. I-beams are widely used in construction and other metal structures.


H-beam is an economical section and high-efficiency profile with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. It is named because its cross section is the same as the English letter "H". Since all parts of the H-beam are arranged at right angles, the H-beam has the advantages of strong bending resistance, simple construction, cost saving and light weight and has been widely used. It is mainly used for: civil and industrial building structures; large-span industrial plants and modern high-rise buildings, especially industrial plants in areas with frequent seismic activity and high-temperature working conditions; long span bridge requiring large bearing capacity, good cross-section stability; heavy equipment; highways; ship skeletons; mine support; foundation treatment and embankment engineering; machine components.
