The steel structure has the following advantages and disadvantages:

Larger structures. Due to the small size of the members, they take up less space and are also easy to transport and install.

The material is uniform and the reliability is high. The steel structure is homogeneous, close to isotropic homogeneous body. The steel is produced by the steel mill, which is strictly controlled and the quality is relatively stable.

Good plasticity and toughness. The tensile and compressive strength of the steel structure is the same, the plasticity and toughness are good, and it is suitable for bearing impact and dynamic loads, and has good seismic performance.

It is convenient for mechanized manufacturing. The steel structure is made of rolled profiles and steel plates in the factory, which is convenient for mechanized manufacturing, with high production efficiency, fast speed, high accuracy of finished products, and easy to guarantee quality, which is a structure with the highest degree of industrialization in the engineering structure.

It is easy to install and the construction period is short. The steel structure is easy to install, the construction period is short, and the economic benefits of investment can be brought into play as soon as possible.
