The main features are as follows:
1. High structural strength: Compared with I-beam, it has a larger section modulus and can save 10-15% of metal under the same load-bearing conditions.
2. Flexible and rich design styles: When the beam height is the same, the bays of the steel structure can be 50% larger than the bays of the concrete structure, making the building layout more flexible.
3. High structural stability: The steel structure is mainly made of hot-rolled H-shaped steel, with a scientific and reasonable structure, good plasticity and flexibility, and high structural stability. It is especially suitable for building structures in some earthquake-prone areas.
4. Increase the effective use area: Compared with concrete structures, the cross-sectional area of steel structure columns is small, which can increase the effective use area of the building. Depending on the building form, the effective usable area can be increased by 4-6%.
5. Easy to process: easy to connect and install structurally, and easy to disassemble and reuse.
6. High degree of industrialized production: Steel structures based on hot-rolled H-shaped steel have a high degree of industrialized production, which is convenient for mechanical manufacturing, intensive production, high precision, easy installation, and easy quality assurance. Real house manufacturing factories, bridge manufacturing factories, industrial factories, manufacturing factories, etc. can be built.
7. Fast construction speed: it occupies a small area, is suitable for all-weather construction, and is less affected by climate conditions. The construction speed of hot-rolled H-shaped steel structures is about 2-3 times that of concrete structures, and the capital turnover rate doubles, reducing financial costs and saving investment.
