1.What are the advantages and functions of H-beam？

Advantages of H-beam:

The wide flanges provide strong bending resistance and stability, effectively resisting vertical loads; the relatively high web ensures good shear resistance. This design achieves extremely high material utilization efficiency, is lighter than solid sections at the same load-bearing capacity, and reduces the deadweight and cost of the structure. More importantly, its wide flange design makes the performance about the strong and weak axes similar, and when used as a column, it has excellent bidirectional stability and can effectively resist lateral forces. In addition, the wide and flat flange surface facilitates the connection to other components (welding or bolting), and the standardized size also simplifies design and construction. Its comprehensive performance and cost-effectiveness make it the preferred high-efficiency profile for beam and column components in modern buildings and engineering structures.

Functions of H-beam:

Building structures: They serve as beams and columns in industrial plants and high-rise buildings, enabling long-span, column-free spaces (such as factories and residential buildings). Their high lateral stiffness makes them suitable for use in earthquake-prone areas.

Infrastructure: They are used in large-span or heavy-load applications such as bridges, port supports, and highway barriers, as well as support piles in underground projects.

Heavy equipment and transportation: They support the frames of trains and ships, as well as heavy machinery, ensuring structural stability.
