Why is steel structure so favored?

Why is steel structure so favored? It is because steel structures have the following advantages.

1. The material has high strength and is lightweight

Steel has high strength and high modulus of elasticity. Compared to concrete and wood, the ratio of density to yield strength of steel structures is relatively low. Therefore, under the same stress conditions, steel structures have smaller cross-sections, lighter self weights, and are easy to transport and install. They are suitable for structures with larger spans, higher heights, and heavier loads.

2. The toughness and plasticity of steel are excellent, the material is very uniform, and the reliability of the structure is high

Suitable for withstanding impact and dynamic loads, with good seismic performance. The internal structure of steel is uniform, almost isotropic and homogeneous. The actual working performance of steel structures will be more in line with the calculation theory. So the reliability of steel structures is high.

3. High degree of mechanization in steel structure manufacturing and installation

Steel structural components are easy to manufacture in factories and assemble on construction sites. The mechanized manufacturing of steel structural components in factories has high precision, high production efficiency, fast assembly speed on site, and short construction period. Steel structure is the most industrialized type of structure.

4. Good sealing performance of steel structure

Due to the welding structure's ability to achieve complete sealing, high-pressure vessels with excellent air and water tightness, as well as large oil tanks and pressure pipelines, can be made.
