H-shaped steel is an economical and efficient section with more optimized section area distribution and more reasonable strength-weight ratio. It is named because its section is the same as the English letter "H". Since all parts of H-beam are arranged at right angles, H-beam has been widely used for its advantages of strong bending resistance, simple construction, cost saving and light structural weight in all directions.Its characteristics are as follows:
1. Wide flange and large lateral stiffness.
2. Strong bending resistance, about 5% - 10% higher than I-beam.
3. The two surfaces of the flange are parallel to each other, making the connection, processing and installation simple.
4. Compared with welded I-beam, it has the advantages of low cost, high accuracy, low residual stress, no need for expensive welding materials and weld detection, and can save about 30% of steel structure manufacturing cost.
5. Under the same section load, the weight of hot-rolled H steel structure is 15% - 20% less than that of traditional steel structure.
6. Compared with the concrete structure, the hot-rolled H steel structure can increase the service area by 6%, while the dead weight of the structure can be reduced by 20% - 30%, reducing the design internal force of

the structure.
7. H-shaped steel can be processed into T-shaped steel, and honeycomb beam can be combined to form various cross sections, which greatly meets the requirements of engineering design and production.
