What is structural steel for building construction?

Steel structure building is a new form of building system. It opens up the industrial dividing line between the real estate industry, construction and installation industry, and metallurgical and refining industry, and integrates it into a new construction industry system. This is what is now generally accepted by most people. Promising steel structure building system.

 

Compared with traditional concrete brick buildings, steel structure buildings use steel plates or steel sections instead of reinforced concrete, which have higher strength, better toughness, and better earthquake resistance. And because the components can be manufactured in a factory and installed on site, the construction period is greatly reduced. In addition, steel can be reused, which can greatly reduce construction waste, is more environmentally friendly, and meets the requirements of green building strategies. Therefore, it is now widely used in industrial buildings, commercial buildings, and civil buildings.

At present, high-structure buildings are increasingly used in high-rise and multi-high-rise buildings, becoming the mainstream building system and a new direction for the future development of the construction industry. The load-bearing structure of steel structure buildings is often composed of beams, columns, trusses and other components made of shaped steel and steel plates. It is composed of roofs, floors, walls and other surrounding structures. Construction section steel usually refers to hot-rolled angle steel, channel steel, I-beam, H-beam, Steel Pipe, etc. A building whose components form a load-bearing structure is called a steel structure building. In addition, the load-bearing capacity formed by cold-rolled thin steel plates, rolled or non-rolled L-shaped, U-shaped, Z-shaped and tubular thin-walled steel sections, as well as components made of them and small steel materials such as angle steel, steel bars, etc. Structural building, generally called light steel structure building. There are also suspension structure buildings using steel cables, which are also steel structure buildings. The strength and elastic modulus of steel are high, and the material is uniform. The steel structure produced has good plasticity and toughness, high accuracy, easy installation, high degree of industrialization, and fast construction. However, it has poor corrosion resistance and fire resistance and requires regular maintenance. .

 

Steel structure components can be manufactured in processing plants and assembled at construction sites, which also provides favorable conditions for steel structure buildings. The advantages of high precision, high efficiency, fast speed and short construction period make steel structure buildings one of the building systems at the modern industrial level.
