1. High-rise structure and high-rise building: these two kinds of structures have more application to steel structure, at the same time, the requirements of the steel structure is very strict, because these structures are mainly subjected to wind load, and the steel structure is convenient for installation and construction, and light weight, the component cross-section small, reduce the wind load, thus achieving greater economic benefits.
2. Heavy industrial plant: the span and column spacing of this plant is relatively large, or with 2-3-storey crane plant, as well as some high-temperature workshop, for such industrial buildings, steel structure is suitable, steel structure of light weight, construction is not too cumbersome.
3. Removable and movable structure: for this kind of engineering with special requirements, the most suitable for the use of steel structure, easy demolition, the use of bolt connection, and easy to assemble and dismantle mobile exhibition halls and movable houses, steel structure light weight, construction machinery in order to reduce structural weight, it must be used steel structure.
4. Lightweight steel structure: with a small weight, construction faster and more than the advantages of steel, the use of single angle steel or thin-walled steel structure of light steel structures and gantry, has been widely used in recent years.
