Steel structure construction is the construction of load-bearing structures composed of steel. Generally, beams, columns, trusses, and other components made of section steel and steel plates form load-bearing structures, which together form building structures such as roofs, floors, and walls.
Construction section steel generally refers to hot-rolled formed angle steel, channel steel, I-beam steel, H-beam steel, and steel pipes. The construction of load-bearing structures composed of its components is called section steel structure construction. In addition, the construction of load-bearing structures composed of thin-walled steel sections such as L-shaped, U-shaped, Z-shaped, and tubular sections formed by cold rolling of thin steel plates, with or without rolled edges, as well as components made of small steel such as angle steel and steel bars, is generally referred to as the construction of lightweight steel structures. The construction of suspension structures using steel cables also belongs to the category of steel structure construction.
Steel structures have the following main advantages:
High material strength, light self weight, good plasticity and toughness, and uniform material
Convenient for factory production and mechanized construction, easy for disassembly, and short construction period;
Having superior seismic performance;
The development of steel structures, which is pollution-free, renewable, energy-saving, and safe, conforms to the principles of sustainable development in construction. It can be said that the development of steel structures is a reflection of the construction civilization in the 21st century.
