H-beam process flow:
Continuous casting billet initial rolling → heating → billet opening → rough rolling unit → finishing rolling unit → sawing → cooling → inspection.

H-beam advantages:

1. High structural strength
Compared with the I-beam, it can save 10-15% of metal under the same bearing conditions.
2. Flexible and rich design style
In the case of the same beam height, the bay of the steel structure can be 50% larger than the bay of the concrete structure, so that the building layout is more flexible.
3. The structure is light in weight
Compared with the concrete structure, it is lighter than the self-weight of the structure. The reduction of the self-weight of the structure reduces the internal force of the structural design, which can make the foundation treatment requirements of the building structure low, the construction is simple, and the cost is reduced.
4. High structural stability
The steel structure mainly composed of H-shaped steel has scientific and reasonable structure, good plasticity and flexibility, and high structural stability. It is suitable for building structures that withstand large vibration and impact loads. It has strong resistance to natural disasters and is especially suitable for some earthquakes. belt building structure. According to statistics, in the world's devastating earthquake disasters of magnitude 7 or above, the steel structure buildings dominated by H-shaped steel have suffered the least damage.
5. Ease of machining
It is easy to connect and install structurally, and also easy to dismantle and reuse.
6. Environmental protection
The use of H-shaped steel can effectively protect the environment, which is manifested in three aspects: (1) Compared with concrete, dry construction can be used, which produces less noise and less dust; (2) Due to the light weight, the foundation construction takes soil Less damage to land resources, in addition to greatly reducing the amount of concrete, reducing the amount of excavated rocks, which is conducive to the protection of the ecological environment; (3) After the service life of the building structure expires, the amount of solid waste generated after the structure is demolished is small , Scrap steel resource recovery value is high.
7. Fast construction speed
It occupies a small area, and is suitable for all-weather construction, and is less affected by climate conditions. The construction speed of the steel structure made of H-shaped steel is about 2-3 times the construction speed of the concrete structure, the capital turnover rate is doubled, and the financial cost is reduced, thereby saving investment.
