Features of prefabricated building steel structures

Special research on steel structures in the construction industry, prefabricated buildings ushered in an upsurge, and prefabricated building steel structures have broad prospects. Steel structure is a structure composed of steel and is one of the main types of building structures.

The steel structure is mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, washing and drying, and galvanizing. Welds, bolts or rivets are often used to connect components or parts.

Because of its light weight and simple construction, it is widely used in large workshops, venues, high-rises and other fields. Steel structures are relatively easy to rust. Generally, steel structures require rust removal, galvanizing or painting, and regular maintenance.

Steel structure is a form of building structure with many advantages. Prefabricated building steel structure is a form of building structure mainly composed of steel plates, section steels, steel pipes, steel cables, etc., connected by welds, bolts or rivets.

Compared with other structural forms such as reinforced concrete structures, masonry structures such as masonry have many advantages such as high strength, light weight, good plastic toughness and seismic performance. Moreover, it is suitable for mechanized processing, with a high degree of industrialization and a short construction period. As steel structure buildings rarely use cement, sand and other materials, environmental pollution problems such as dust, construction waste and noise are greatly reduced, which meets the requirements of sustainable development.

As one of the important building structure, steel construction is widely used in housing construction, machinery, energy, municipal facilities and other industries. There is no consistent standard for the classification of steel structures. According to the application field, it can be divided into five categories: equipment steel structures, heavy construction steel structures, light construction steel structures, bridge steel structures, and space steel structures.

There is still a lot of room for improvement in the penetration rate of prefabricated building steel structures. The steel structure industry is still in the growth stage, and steel structures account for a relatively low proportion of construction steel.
