What are the main features and uses of welded carbon steel H-shaped steel?

1. High structural strength
The modulus of carbon steel I-beam is larger. When the bearing conditions are the same, 10-15% of metal can be saved.

2. The design style is flexible and rich
In the case of the same beam height. The bays of the steel structure can be 50% larger than the bays of the concrete structure. Thereby making the building layout more flexible.

3. Light structure
Compared with the weight of the concrete structure, it is lighter, and the weight of the structure is reduced. The internal force of the structural design is reduced, and the requirement for the foundation treatment of the building structure is low, the construction is simple and the cost is reduced.

4. High structural stability
The steel structure mainly made of hot-rolled carbon steel H-shaped steel has scientific and reasonable structure, good plasticity and flexibility. The structure has high stability and is suitable for building structures that are subjected to large vibration and shock loads. Strong ability to resist natural disasters, especially suitable for some building structures where earthquakes occur.

5. Increase the effective use area of the structure
Compared with concrete structure. The steel structure column has a small cross-sectional area. Thereby, the effective use area of the building can be increased. Depending on the different forms of the building, it can increase the effective use area by 4-6%.

6. Easy to machine processing
It is easy to connect and install the structure, and also easy to dismantle and reuse.

7. Environmental protection
The use of carbon steel section steel can effectively protect the environment, specifically in three aspects: First, compared with concrete, dry construction can be used, resulting in less noise and less dust; second, due to reduced weight. The amount of soil taken for foundation construction is small, and the damage to land resources 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. The third is the solid waste generated after the service life of the building structure expires and after the structure is demolished The amount is small, and the value of scrap steel recycling is high.
