H-beams are a new type of economical steel used in construction.
They are commonly used in large buildings requiring high load-bearing capacity and good cross-sectional stability (such as factories and high-rise buildings), as well as bridges, ships, lifting and transportation machinery, equipment foundations, supports, and foundation piles.
