1. According to the flange width of the product, it is divided into wide flange, middle flange and narrow flange H-beam.
2. According to the product use, it is divided into H-beam, H-beam column, H-beam pile and H-beam with extremely thick flange.
3. According to the mode of production, it can be divided into welded H-beam and rolled H-beam.
4, according to the size specification is divided into large, medium and small H-beam.
Extended data:
The steel structure with hot-rolled H-beam is scientific and reasonable in structure, good in plasticity and flexibility, high in structural stability and strong in natural disaster resistance, especially for some building structures in earthquake-prone areas. According to statistics, among the devastating earthquake disasters above magnitude 7 in the world, the damage of H-beam steel structures is the least.
And that effective use area of the structure is increase. Compared with concrete structure, the cross-sectional area of steel structure column is smaller, which can increase the effective use area of the building, and according to different forms of the building, it can increase the effective use area by 4-6%.
