What is H-shaped steel

H section steel is a new type of economical building steel. It is an economic cross-section steel with good mechanical properties, which is optimized and developed for I-beam steel. It is named because its section is the same as the English letter "H".

The main features are as follows:

1. high structural strength: compared with I-steel section modulus is large, under the same bearing conditions can save metal 10-15%.

2. Flexible and rich design style: in the case of the same beam height, the steel structure can be 50% larger than the concrete structure, so that the building layout is more flexible.

3. high structural stability: the steel structure is dominated by hot rolled H-beam steel, scientific and reasonable structure, good plasticity and flexibility, high structural stability. Especially suitable for some earthquake prone areas of the building structure.

4. increase the effective use area: compared with concrete structure, steel structure column cross-sectional area is small, can increase the effective use area of the building. Depending on the building form, the effective use area can be increased by 4-6%.

5. easy processing: easy structural connection and installation, but also easy to disassemble and reuse.

6. High degree of industrial production: The steel structure based on hot rolled H beam has a high degree of industrial production, which is convenient for mechanical manufacturing, intensive production, high precision, convenient installation and easy quality assurance. You can build real house manufacturing plants, bridge manufacturing plants, industrial plants, manufacturing plants, etc.

7. the construction speed is fast: covers an area of small, suitable for all-weather construction, the influence of climate conditions is small. The construction speed of hot rolled H-beam steel structure is about 2-3 times that of concrete structure, and the capital turnover rate is doubled, which reduces the financial cost and saves investment.
