Steel structure is one of the main building structure.It is composed of beams, columns, trusses and other components made of steel plates or sections. The components are connected by welding, bolting, riveting and other methods. It is widely used in the fields of super high-rise buildings, long-span buildings, Bridges, tower mast structures, removable structures and structures requiring light deadweight.The application in the field of public construction is booming. In addition to factories and multi-storey houses, it is extended to super high-rise buildings, large-span convention and exhibition centers, sports stadiums, large transportation buildings, etc. At present, more than one thousand steel structure super high-rise buildings over 200m are under construction or have been completed, and steel structure is developing in the direction of higher, wider and lighter.
Steel structure commonly used steel is mainly divided into two categories:
(1) Ordinary carbon steel
(2) Low alloy high strength structural steel
Below Q275 is carbon steel, above Q295 is low alloy high strength structural steel.
Commonly used brands are Q235, Q355 (formerly Q345), Q390, Q420, Q460.

Insulation property
The thermal insulation material used is mainly polyurethane sandwich board, which has good thermal insulation effect.The thermal insulation board used for the external wall effectively avoids the phenomenon of “cold bridge” on the wall and achieves good thermal insulation effect.The thermal resistance of the polyurethane sandwich plate with thickness of about 50mm can be equivalent to that of a brick wall with thickness of 1m.
Sound insulation
Sound insulation effect is an important index to evaluate the building, light steel system installed Windows are hollow glass, sound insulation effect is good, sound insulation of more than 40 decibels;The wall, which consists of polyurethane sandwich board insulation material, has a sound insulation effect of up to 80 decibels.
Wind resistance
Section steel structure is light in weight, high in strength, good in overall rigidity and strong in deformation.The weight of the building is only one-fifth of that of the brick-concrete structure, and it can resist hurricanes of 70 meters per second, so that life and property can be effectively protected.
