Hot-rolled H-shaped steel reasonably distributes the aspect ratio of the cross-section size according to different uses and has excellent mechanical properties and excellent practical performance. 

The structure is light in weight. It is lighter than the self-weight of the concrete structure. The reduction of the structure's self-weight reduces the internal force of the structural design, which can reduce the need for basic processing of the building structure, simplify the construction, and reduce the cost.

The steel structure mainly composed of hot-rolled H-shaped steel has a scientific and reasonable structure, good plasticity and flexibility, and high structural stability. It is suitable for building structures that bear large vibration and impact loads. It has strong resistance to natural disasters and is especially suitable for some multi-purpose structures. Architectural structures in earthquake-prone zones. According to statistics, when a devastating earthquake of magnitude 7 or above occurs in the world, steel structure buildings dominated by H-shaped steel suffer the least damage. 

Add the useful usable area of the structure. Compared with the concrete structure, the cross-sectional area of the steel structure column is small, which can increase the effective use area of the building. Depending on the different forms of the building, the effective use area can be increased by 4-6%.  

Compared with welded H-shaped steel, it can significantly save labor and materials, reduces the consumption of raw materials, power, and labor, has low residual stress, and has a good appearance and surface quality. 

It is convenient for machining, structural connection, and installation, and is also easy to remove and reuse.

The use of H-shaped steel can effectively protect the environment, which is reflected in three aspects: First, compared with concrete, dry construction can be used, which produces less noise and less dust; second, due to the reduced weight, less soil is taken for basic construction, which affects the land. The resource damage is small. In addition, the amount of concrete is greatly reduced, and the amount of rock excavation is reduced, which is conducive to the protection of the ecological environment; thirdly, after the service life of the building structure expires, the amount of solid waste generated after the structure is dismantled is small, and the recycling value of scrap steel resources is high. 

The steel structure mainly composed of hot-rolled H-shaped steel has a high degree of industrial manufacturing, is convenient for mechanical manufacturing, and intensive production, has high precision, is easy to install, and is easy to ensure quality. It can build real house manufacturing factories, bridge manufacturing factories, industrial plant manufacturing factories, etc.

The project construction speed is fast, the area is small, and it is suitable for all-weather construction and is less affected by climate conditions. The construction speed of steel structures made of hot-rolled H-shaped steel is about 2-3 times that of concrete structures. The capital turnover rate is doubled, which reduces financial costs and thus saves investment.
