What are the characteristics of H-beams?

Characteristics of H-beams

1. High structural strength

Compared with I-beam, the section modulus of H-shaped steel(H-beams)is large, and the metal can be saved by 10-15% when the bearing conditions are the same.

2. Flexible and rich design style

With the same beam height, the steel structure can be 50% larger than the concrete structure, making the building more flexible.

3. Lightweight structure

Compared with the self-weight of the concrete structure, the self-weight of the structure is reduced, and the internal force of the structural design is reduced, which can reduce the requirements for the foundation treatment of the building structure, facilitate the construction, and reduce the cost.

4. High structural stability

Hot-rolled H-beam steel structure 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 shock loads, and has strong resistance to natural disasters. Building structure in earthquake zone. According to statistics, in the world's magnitude 7 or more devastating earthquake disasters, steel structure buildings dominated by H-beams suffered less damage.

5. Increase the effective 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 form of the building, it can increase the effective use area by 4-6%.

6. Easy machining

Easy to connect and install, easy to remove and reuse.

7. Environmental protection

The use of H-shaped steel can effectively protect the environment, which is specifically manifested in three aspects: first, compared with concrete, dry construction can be used, which generates less noise and less dust; second, due to the reduction of self-weight, less soil extraction for foundation construction, and Small damage to land resources, in addition to reducing the amount of concrete, reducing the amount of rock excavation, is conducive to the protection of the ecological environment; the third is that after the service life of the building structure expires, the amount of solid waste generated is small after the structure is demolished, and the value of scrap steel resources is high.
