What are the characteristics of profile steel?

Light weight of the structure: Compared with the weight of the concrete structure, the weight of the structure is reduced, which reduces the internal force of the structure design, which can make the foundation processing requirements of the building structure lower, the construction is simple, and the cost is reduced.

1. High structural strength: Compared with I-beam, the section modulus is larger, which 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, 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 structure is reduced, which reduces the internal force of the structure design, which can make the foundation processing requirements of the building structure lower, the construction is simple, and the cost is reduced.
4. High structural stability: The steel structure mainly made 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 can withstand large vibration and impact loads and has the ability to resist natural disasters. Strong, especially suitable for some building structures in earthquake-prone areas. 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.
5. Increase the effective use area of the structure: 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 different forms of the building, the effective use area can be increased by 4-6%.
