The steel structure platform, also known as the steel structure sandwich, is characterized by its fully assembled structure and flexible design. It can be designed and manufactured according to different site conditions to meet site requirements, functional requirements, and logistics requirements. Steel structure platforms occupy a certain proportion in industrial plants and structures, especially with the expansion of factory production workshops. Building new steel structure plants is uneconomical and time-consuming, making steel structure platforms increasingly important. Nowadays, the design weight of steel structure platforms has been increasing. Therefore, the design of steel structure platforms should not only meet the requirements of process production, but also pay attention to the rationality of the structure in platform layout, material selection, manufacturing and installation.
