The prefabricated factory shed of steel structure refers to that the main load-bearing components are composed of steel. Including steel columns, steel beams, steel structure foundations, steel roof trusses, steel roofs. Note that steel structure walls now use new thermal insulation materials.
Industrial and civil buildings made of steel are called steel structure buildings. Due to the increase of steel production, many enterprises have started to use prefabricated factory sheds, which can also be divided into light and heavy steel structure factory sheds. Compared with structures made of other materials, steel structures are cheap and have the following characteristics:
1. High strength of steel and light weight of structure
Although the density of steel is higher than that of other building materials, its strength is very high. Under the same stress, the steel structure has small dead weight and can be made into a structure with large span.
2. Good plasticity and toughness of steel
The steel has good plasticity, and the steel structure will not break suddenly due to accidental overload or local overload under normal circumstances. The good toughness of steel makes the structure more adaptable to dynamic load.
3. The steel material is uniform and reliable
The internal structure of steel is uniform and isotropic. The actual working performance of the steel structure is in good accordance with the theoretical calculation results, so the reliability of the steel structure is high.
4. The steel is weldable
Due to the weldability of steel, the connection of steel structure is greatly simplified, and it is suitable for manufacturing structures with various complex shapes.
5. High industrialization of steel structure fabrication and installation
The fabrication of the steel structure of the prefabrication factory shed is mainly carried out in a specialized metal structure factory, so the fabrication is simple and accurate. The fabricated components are transported to the site for installation with high degree of assembly, fast installation speed and short construction period.
6. Good sealing performance of steel structure
The internal structure of steel is very dense, and it is easy to achieve tightness without leakage when welding connection is adopted, even when rivet or bolt connection is adopted.
7. Heat resistance of steel structure
When the surface temperature of steel is within 1500C, the strength of steel changes little, so the steel structure is suitable for production workshops with high temperature.
