What are the characteristics of steel structures? A Yunnan steel structure manufacturer explains.

Yunnan Steel Structure Manufacturer ： Steel structure is one of the main building structures. Steel has the characteristics of high strength, light weight, and high rigidity, making it particularly suitable for building large-span, super-high, and super-heavy buildings.

　　This material has good uniformity and isotropy, is an ideal elastic body, and conforms to the basic assumptions of general engineering mechanics. It has good plasticity and toughness, can have large deformations, can withstand dynamic loads well; short construction cycle; high degree of industrialization, allowing for highly mechanized specialized production; high processing precision, high efficiency, good airtightness, and can be used to build gas cylinders, oil tanks, transformers, etc.

　　Yunnan Steel Structure Manufacturer: Its disadvantages are poor fire resistance and corrosion resistance. It is mainly used for heavy workshops, workshops under dynamic loads, plate and shell structures, high-rise television towers and mast structures, large-span structures such as bridges and warehouses, and load-bearing frames for high-rise and super-high-rise buildings.

　　Yunnan Steel Structure Manufacturer ： In the future, steel structures will need to research high-strength steel to significantly improve its yield strength; in addition, new steel sections should be rolled, such as H-beams (also known as wide flange beams), T-beams, and pressed steel plates, to meet the needs of large-span structures and super-high-rise buildings.

　　Yunnan Steel Structure Manufacturer ： Steel structures are divided into light steel and heavy steel. There is no unified evaluation standard, and many experienced designers or project managers often cannot fully explain clearly. Some data can be used for comprehensive consideration and judgment.

　　Yunnan Steel Structure Manufacturer ： Quality Control of Steel Structure Installation ：

　　1. Before installation, the construction unit should check the product qualification certificate, design documents, and pre-assembly records of the components, and record the dimensions of the components again. If the deformation and defects of the steel structure exceed the allowable deviation, they should be processed.

　　Before installation, a detailed measurement and correction process should be prepared. For thick steel plate welding, a process test simulating the product structure should be carried out before welding installation, and corresponding construction processes should be compiled. The assembled trusses should have a certain pre-set camber.

　　2. After the steel structure is hoisted into place, the control points of the component positioning axis, elevation, etc., which meet the design requirements, are measured and marked, and the quality of hoisting and docking is checked before welding. Temporary supports and steel wire ropes are installed to ensure the safety and stability of the steel truss during construction.

　　3. When installing the steel structure, the construction unit should submit the elevation dimensions, welding, and painting of each component after hoisting to the supervisor for acceptance.

　　Yunnan Steel Structure Manufacturer ： According to the building height and design requirements, frame, frame support, cylinder, and giant frame structures are used respectively. The components can be steel, reinforced concrete, or steel pipe concrete. Steel components are light in weight, have good ductility, can be welded or rolled, and are suitable for super-high-rise buildings. Reinforced concrete components have high rigidity and good fire resistance and are suitable for medium and high-rise buildings or lower structures. Steel pipe concrete construction is simple and is only used for column structures.

　　Yunnan Steel Structure Manufacturer ： Steel structure space is light in weight, high in rigidity, beautiful in shape, and fast in construction. The spherical node plane grid, variable-section multi-layer grid, and shell with steel pipes as members are the structural types of space steel structures in China. It has the advantages of large spatial rigidity and low steel consumption, and can provide complete CAD in design, construction, and inspection procedures. In addition to truss structures, there are also large-span cable structures and cable membrane structures.
