H-shaped steel is a widely used profile in today's steel structure buildings. The surface of H-shaped steel has no inclination and the upper and lower surfaces are parallel. The cross-sectional properties of H-shaped steel are significantly better than traditional I-beam, channel steel and angle steel. So what are the characteristics of H-shaped steel?

NO.1
Compared with I-beam steel, its structural strength is high and its section modulus is large. When the load-bearing conditions are the same, it can save 10-15% of metal.

NO.2
Flexible and rich design style
When the beam height is the same, the bays of the steel structure can be 50% larger than those of the concrete structure, making the building layout more flexible.

NO.3
The structure is light in weight
It is lighter than the self-weight of a concrete structure. The reduction of the structure's self-weight reduces the internal force of the structural design, which can make the building structure foundation processing requirements lower, the construction is simple, and the cost is reduced.

NO.4
High structural stability
The steel structure mainly made of hot-rolled H-shaped steel has a scientific and reasonable structure, good plasticity and flexibility, and high structural stability. It is suitable for building structures that can withstand large vibration and impact loads. It has strong resistance to natural disasters and is especially suitable for some multi-purpose buildings. Building structures in earthquake zones. According to statistics, when a devastating earthquake of magnitude 7 or above occurs in the world, steel structure buildings dominated by H-shaped steel suffer the least damage.

NO.5
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%.

NO.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, has low residual stress, and has good appearance and surface quality.

NO.7
Easy to machine
Easy to structurally attach and install, as well as easy to dismantle and reuse.

NO.8
Environmental friendly
The use of H-shaped steel can effectively protect the environment, which is reflected in three aspects: First, compared with concrete, dry construction can be used, which produces less noise and less dust; second, due to the reduced weight, less soil is taken for foundation construction, which is The damage to land resources is small. In addition, the amount of concrete is greatly reduced, and the amount of rock excavation is reduced, which is conducive to the protection of the ecological environment. Third, after the service life of the building structure expires, the amount of solid waste generated after the structure is dismantled is small, and the recycling value of scrap steel resources is high. .

NO.9
High degree of industrial production
The steel structure mainly made of hot-rolled H-shaped steel has a high degree of industrialization, is convenient for mechanical manufacturing, intensive production, high precision, easy installation, and easy to ensure quality. It can be built into a real house manufacturing factory, bridge manufacturing factory, industrial plant manufacturing factory, etc. . The development of steel structures has created and promoted the development of hundreds of emerging industries.
