The steel structure exhibition hall is composed of steel materials. By comparing the steel structure with the traditional concrete structure, it can be found that the steel structure building has the characteristics of high quality, good seismic performance, fast construction, green environmental protection, etc. Although the bulk density of the steel structure is larger, its strength is much higher than that of other building materials alone. Therefore, under the same load and conditions, Steel structures are lighter than other structures and easier to transport and install.
