Steel Structure Buildings

It is a new type of building system that breaks through the industry boundaries between real estate industry, construction industry and metallurgy industry, and collects into a new industry system, which is the steel structure building system that is generally favoured by the industry.

Compared with the traditional concrete building, steel structure building replaces reinforced concrete with steel plate or steel section, which has higher strength and better seismic resistance. And because the components can be factory-made and installed on-site, the construction period is greatly reduced. Due to the reusability of steel, it can greatly reduce the construction waste and is more environmentally friendly, so it is widely adopted by countries around the world and applied in industrial and civil buildings.

The use of steel structure building in high-rise and ultra-high-rise buildings is becoming more and more mature, and it is gradually becoming the mainstream construction process, which is the development direction of the future construction.

Steel structure building is a building with a load-bearing structure made of construction steel. Usually, beams, columns, trusses and other components made of steel sections and plates form the load-bearing structure. Together with the roof, floor, wall and other enclosing structures, they form a whole plant building.

Construction steel usually refers to hot-rolled steel angles, channels, I-beams, H-beams and steel pipes. By its components constitute the load-bearing structure of the building called section steel structure building. In addition by the thin steel plate cold rolled forming, rolled edge or not rolled edge of the L-shaped, U-shaped, Z-shaped and tube-shaped thin-walled steel, and its and small steel such as angle, rebar, etc. made of components of the load-bearing structure of the building, generally known as the lightweight steel structure building. There are also suspension buildings using steel cables, which are also steel buildings.

Steel has high strength and modulus of elasticity, uniform material, good plasticity and toughness of the steel structure, high accuracy, easy to install, high degree of industrialisation, faster construction, but poor resistance to corrosion and fire, and requires frequent maintenance. 

Advantages:

1. Greatly save construction time, construction is not affected by seasons.

2. Increase the use area of residential space, reduce construction waste and environmental pollution.

3. Construction materials can be reused, pulling the development of other new building materials industry.

4. Good anti-seismic performance, easy to transform, flexible and convenient in use, bringing comfort to people and so on.

5. High strength, light weight, high component safety affluence, reduce building costs

6. In line with the national sustainable development strategy, low-carbon, green, environmental protection, energy saving, etc. is the national key to support the industry.

Disadvantages:

1. Heat-resistant, not fire-resistant, the need for surface coating fireproof paint

2. Easy to be corroded, the surface needs to be coated with anti-corrosion coatings to reduce or avoid corrosion and improve durability.
