Superior Metal Structures
Steel structure refers to the structural form of steel plate and hot-rolled, cold-formed or welded profiles connected by connectors that can bear and transfer loads. Superior metal structures system has comprehensive advantages such as light weight, factory manufacturing, fast installation, short construction period, good seismic performance, fast investment recovery, less environmental pollution and so on. Compared with reinforced concrete structure, steel structure has the unique advantages of "high, large and light" in the world, especially in developed countries and regions, steel structure in the field of construction engineering has been reasonable and widely used. Steel structure has been applied reasonably and widely in the field of construction engineering.
Superior metal structures is widely used in various engineering construction, such as steel bridge, steel plant, steel gate, all kinds of large pipeline containers, high-rise buildings and tower crane.
Categories of Superior Metal Structures:
Steel structure can be divided into light steel structure, high-rise steel structure, residential steel structure, space steel structure and bridge steel structure.
Light steel structure:
Light Gauge Steel Construction is mainly used in load-bearing buildings that do not bear large loads. Light H-type steel is used as door profile steel frame support, C-type or Z-type cold-formed thin-wall steel is used as wall beam, and profiled steel sheet is used as roof or building envelope. It has the characteristics of earthquake resistance, wind resistance, durability, heat preservation, sound insulation and so on.
High-rise steel structure:
Generally, it refers to the structural system of six layers or more than 30 meters, which is connected or welded by profile steel and steel plate. It is widely used in modern high-rise and super high-rise steel structures.
Residential steel structure:
It is a new type of building structure system, it is the section of H type, Z type and U type steel members connected, through fixing the main frame of the house, and then use the panel as the roof and wall, along with the doors and Windows to form a complete building system, which has the characteristics of low cost, light weight, beautiful appearance and short construction period.
Space steel structure:
Generally speaking, it is the steel structure construction with a large span, such as factories, stadiums, bus stations, railway stations, airports, etc. Bird's Nest is a typical representative of space steel structure, with characteristics of complexity, diversity.
Bridge steel structure:
It is mainly used for bridge structure. The main materials are steel plate, profile steel and high-strength steel beam. In a humid environment for a long time, it is easy to rust and the maintenance cost is high.
