H Beam 250x250

H beam 250x250 is a steel material with a cross-section shape similar to the letter "H". It has high strength, stability and good load-bearing capacity and is widely used in buildings, bridges and industrial equipment.

H beam 250x250 is divided into hot-rolled H-beam and welded H-beam (H). Hot-rolled H-beam is further divided into wide flange H-beam (HW), medium flange H-beam (HM) and narrow flange H-beam (HN).

1. HW is the H-beam height and flange width are basically equal; it is mainly used for steel core columns in reinforced concrete frame structure columns, also known as rigid steel columns; it is mainly used for columns in steel structures

2. HM is the H-beam height and flange width ratio is roughly 1.33~~1.75. It is mainly used in steel structures: used as steel frame columns and frame beams in frame structures that bear dynamic loads; for example: equipment platforms

3. HN is the H-beam height and flange width ratio ≥2, mainly used for beams; the use of I-beams is equivalent to HN steel

High structural stability: The steel structure mainly composed of hot-rolled H-shaped steel has a scientific and reasonable structure, good plasticity and flexibility, and high structural stability. H beam 250x250 is suitable for building structures that bear large vibration and impact loads, and has strong resistance to natural disasters. It is especially suitable for building structures in some earthquake-prone areas. According to statistics, in the devastating earthquake disasters of magnitude 7 or above in the world, steel structures mainly composed of H-shaped steel suffered the least damage.

Increase the effective use area of the structure: Compared with concrete structures, the cross-sectional area of steel structure columns is small, which can increase the effective use area of the building. Depending on the different forms of the building, the effective use area can be increased by 4-6%.

Saving labor and materials: Compared with welded H-shaped steel, it can significantly save labor and materials, reduce the consumption of raw materials, energy and labor, have low residual stress, and good appearance and surface quality.
