" Prefabricated steel structure building is a green building, its application can save resources, reduce pollution, improve construction efficiency and quality and safety level." During the NPC and CPPCC sessions, NPC deputies brought suggestions on vigorously promoting steel structures.
Compared with traditional concrete structures, fabricated steel structures have obvious advantages in construction, environmental protection, earthquake resistance and other aspects: the construction speed is increased by 30%-50%; Low emission of noise, dust and carbon dioxide; The seismic performance is good. It is worth mentioning that 70% of steel in steel structure can be recycled. It can be said that in construction, construction, demolition, remote reconstruction and other aspects, prefabricated steel structure buildings all reflect the characteristics of green buildings.
However, in sharp contrast to many benefits, the proportion of steel structures in China is only 5%, which is far lower than that in developed countries of 30-40%. In this regard, the state should practice the concept of green development and vigorously promote fabricated steel structures.
The most important thing is to strengthen policy support. In recent years, the state has successively issued a series of policies to promote green buildings and develop fabricated steel structure buildings, proposing to strive to make fabricated buildings account for 30% of the newly-built building area in about 10 years.
The introduction of the above policies has laid a foundation for the development of the industry. On this basis, relevant departments should formulate special support policies in the areas of financial subsidies, tax concessions, land use security, administrative licensing, etc.
What should not be ignored is that while promoting the development of new urbanization, the development of steel structure buildings can also effectively resolve excess capacity in the steel industry and promote structural reform on the supply side.
