In the industry, steel structures can usually be divided into five categories: light steel structures, high-rise steel structures, residential steel structures, spatial steel structures, and bridge steel structures.
- Light steel structure
Mainly used in load-bearing buildings that do not bear large loads, lightweight H-shaped steel is used as the support for the door steel frame, C-shaped or Z-shaped cold-formed thin-walled steel is used as the wall beam, and profiled steel plate is used as the roof or enclosure structure. It has characteristics such as seismic resistance, wind resistance, durability, insulation, and sound insulation.
- High rise steel structure
Generally, it refers to a structural system consisting of six floors or more than 30 meters, connected or welded with section steel or steel plates, which is widely used in modern high-rise and super high-rise steel structures.
- Residential steel structure
It is a new type of building structural system that connects steel components with H-shaped, Z-shaped, and U-shaped sections, and forms the main frame of the house by fixing it. It is then used as the roof and wall, and paired with doors and windows to form a complete building system. It has the characteristics of low cost, light weight, beautiful appearance, and short construction period.
- Spatial steel structure
Generally speaking, it refers to steel structure buildings with large spans, such as factories, gyms, bus stations, train stations, airports, etc. The Bird’s Nest is a typical representative of spatial steel structures, with characteristics such as complexity and diversity.
- Bridge steel structure
It is mainly used for bridge structures, mainly made of steel plates, profiles, and high-strength steel beams. Due to their long-term exposure to humid environments, they are prone to corrosion and have high maintenance costs.
