What Is H Beam?

H-section steel beam is a kind of economical section material with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. It is named because its section is same as English letter "H". Due to the right-angle arrangement of all parts of H-beam, it has been widely used in steel structure buildings for its strong bending resistance, simple construction, cost saving and light structural weight in all directions.

Features

1. High structural strength: Compared with I-beam, the section modulus is larger, and the metal can be saved by 10-15% under the same bearing conditions. The design style is flexible and abundant: in the case of the same beam height, the steel structure will be 50% larger than the concrete structure bay, thus making the building layout more flexible.

2. Light structure weight: Compared with concrete structure, the steel structure’s weight is reduced, which reduces the internal force of structure design, simplifies construction and decreases the cost.

3. High structural stability: The steel structure mainly made of H-section steel has scientific and reasonable structure with good plasticity and flexibility, and high structural stability. It is suitable for building structures that withstand large vibration and impact loads.

4. Increase the effective use area of the structure: Compared with the concrete structure, the steel structure column has a small cross-sectional area, which can increase the effective use area of the building.

5. Save labor and material: Compared with welding H-shaped steel, it can save labor and material, and reduce the consumption of raw materials, energy and labor.
