1. High structural strength: compared with I-beam steel, H-beam steel has a larger section modulus, which can save 10-15% of metal under the same load-bearing conditions.
2. The design style is flexible and rich: in the case of the same beam height, the bay of the H-beam steel structure can be 50% larger than that of the concrete structure, thus making the building layout more flexible.
3. Light weight of the structure: compared with the weight of the concrete structure, the weight of the H-beam steel is lighter. The reduction of the structural self-weight of the H-beam steel reduces the internal force of the structural design, which can reduce the requirements for the foundation treatment of the building structure, the construction is simple and the cost is reduced.
4. High structural stability: the steel structure mainly made of hot-rolled H-beam steel has scientific and reasonable structure, good plasticity and flexibility, and high structural stability. It is suitable for building structures that withstand large vibration and impact loads, and has the strong ability to resist natural disasters, especially suitable for some building structures with frequent earthquake occurrence zones.
5. High degree of industrialized manufacturing: the steel structure mainly made of hot-rolled H-beam steel has a high degree of industrialized manufacturing, which is convenient for mechanical manufacturing, intensive production, high precision, convenient installation, and easy to ensure quality. It can be built into a real house manufacturing factory and bridge manufacturing factories, industrial plants, manufacturing plants, etc.
6. The construction speed of the project is fast: the area is small, and it is suitable for all-weather construction, and it is less affected by the climatic conditions. The construction speed of the steel structure made of hot-rolled H-beam steel is about 2-3 times that of the concrete structure, and the capital turnover rate is doubled, which reduces the financial cost and saves investment.
