Structural Steel Buildings

A 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 and wall enclosure structure, they form a whole plant building.

Construction steel usually refers to hot-rolled steel angle, channel, I-beam, H-beam and steel pipe. By its components constitute the load-bearing structure of the building called section steel structure building. In addition by the thin steel 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 angles, bars, etc. made of components formed by the load-bearing structure of the building, generally referred to 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, made of steel structure with good plasticity and toughness, high accuracy, easy to install, high degree of industrialization, faster construction, but poor resistance to rust and corrosion and fire resistance, and need frequent maintenance.

Advantages

1.Greatly save construction time, construction is not affected by the season

2.Increase space usage area, reduce construction waste and environmental pollution.

3.Construction materials can be reused to stimulate the development of other new building materials industry.

4.Good anti-seismic performance, easy to remodel, flexible and convenient in use, bringing comfort to people, etc.

5.High strength, light weight, high safety affluence of components, reducing the cost of buildings.

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 but not fire-resistant, need to apply fire-resistant coatings on the surface.

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