The Advantages of H Section Beam

The Advantages of H Section Beam

H-section steel is a kind of economic and high-efficiency section with a more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. It is named because its section is the same as the English letter "H". Since the various parts of the h-shaped steel are arranged at right angles, the H-shaped steel has the advantages of strong bending resistance, simple construction, cost-saving, and light structure weight in all directions, and has been widely used. Its advantages are as follows:


1. High structural strength


Compared with the I-beam, the section modulus is larger, and the metal can be saved by 10-15% under the same bearing conditions.


2. The design style is flexible and rich:


In the case of the same beam height, the steel structure bay can be 50% larger than the concrete structure bay, thus making the building layout more flexible.


3. Light structure


Compared with the concrete structure, it is lighter than the concrete structure, and the structural weight is reduced, which reduces the internal force of the structure design, and can make the building structure foundation treatment requirements low, and it is easy to construct and lower in cost.


4. High structural stability


The steel structure mainly made of hot-rolled 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 a strong resistance to natural disasters and is especially suitable for building a structure where the earthquake occurred.


5. 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. Depending on the different forms of the building, the effective use area can be increased by 4~6%.


6. Save labor and materials


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


7. Easy for machining


8. Environmental protection


9. High degree of industrial production


The steel structure mainly made of hot-rolled H-section steel has a high degree of industrial production, which is convenient for mechanical manufacturing and intensive production. It has high precision, convenient installation, and quality assurance. It can be built into a real house manufacturing factory, bridge manufacturing factory, and industrial plant manufacturing factories, and so on. The development of steel structures has created and promoted the development of hundreds of emerging industries.


10. Fast construction speed


It occupies a small area, is suitable for all-weather construction, and is less affected by climatic conditions.
