What is H-shaped steel? What are the characteristics of H-beam steel?

The European standard H-beam steel is a new type of economical construction steel. It is an economical section steel with good cross-sectional mechanical properties that is optimized and developed for I-beams, named after the same section as the English letter "H".

The main features are as follows:

1. High structural strength: Compared with I-beam, it has a larger cross-sectional modulus and can save 10-15% of metal under the same bearing conditions.

2. Flexible and rich design style: When the beam height is the same, the steel structure bay can be 50% larger than the concrete structure bay, making the building layout more flexible.

3. High structural stability: The steel structure is mainly made of hot-rolled H-beams, with a scientific and reasonable structure, good plasticity and flexibility, and high structural stability. Especially suitable for building structures in earthquake prone areas.

4. Increasing the effective usable area: Compared to concrete structures, steel structural columns have a smaller cross-sectional area, which can increase the effective usable area of the building. According to different building forms, the effective usable area can be increased by 4-6%.

5. Easy to process: Easy to connect and install the structure, as well as easy to disassemble and reuse.

6. High degree of industrial production: Steel structures mainly made of hot-rolled H-beams have a high degree of industrial production, which is convenient for mechanical manufacturing, intensive production, high precision, convenient installation, and easy to ensure quality. Real housing manufacturing factories, bridge manufacturing factories, industrial factories, manufacturing factories, etc. can be built.

7. Fast construction speed: Small footprint, suitable for all-weather construction, and less affected by climate conditions. The construction speed of hot-rolled H-beam steel structures is about 2-3 times that of concrete structures, and the capital turnover rate is doubled, reducing financial costs and saving investment.
