Development Status and Prospects of Light Steel Structure Prefabricated Buildings

With the continuous development of globalization, people’s living environment is also changing, promoting the continuous development of housing construction towards energy-saving and environmental protection. Steel structure prefabricated buildings can well meet the development needs of modern people. Its energy-saving and environmental protection characteristics conform to the development requirements of the times and fully promote steel structure prefabricated buildings.

The so-called prefabricated steel structure building is not a prefabricated steel structure, but a prefabricated building for structural construction with steel structure as the carrier. Steel structures are born for assembly, and only serve as local welding, which does not change their internal components. With the continuous improvement of economic level, the country pays more and more attention to steel structure prefabricated buildings, fully promotes steel structure prefabricated buildings, and effectively saves costs and labor.

Development Status of Prefabricated Buildings In the development of the past few years, it has been clearly required to fully implement prefabrication technology to promote the development process of modern construction industry. Light steel structure prefabricated buildings are green and environmentally friendly, and improve the problem of low efficiency based on traditional prefabricated building structures. However, due to the restrictions of funds and technology, although prefabricated building structures have developed to a certain extent, there are still many problems in the scale of development. At present, most areas still use traditional products such as floor slabs, and it is expected that cast-in-place technology, although these have strong seismic effects, lack certain convenience, and the cost is relatively high, and it is not easy to store during construction. The introduction of light steel structure prefabrication can not only save resources and costs, but also reduce labor, shorten the construction period of the project, and improve the quality of construction.

In the past development, due to the low market acceptance of steel structures, the lack of complete industry standards, and the insufficient support of the government, the high cost of engineering, etc., the industrial chain of steel structure prefabricated residences is not perfect, and the construction supporting industry cannot keep up with the development of steel structures. , And the price is high, so steel structure public buildings mostly use curtain walls and floor slabs, introduce technology and products from abroad, combine with domestic technology, and develop a new type of steel structure technology system, so that steel structure prefabricated buildings can develop better and better.

Development Advantages of Prefabricated Buildings

1. Green and environmentally friendly Steel structure prefabricated buildings are characterized by green, environmentally friendly, and low-carbon energy-saving. They are combined with the principle of sustainable development advocated by our country. The construction process of steel structures is through various components assembled, so it is convenient for demolition and construction, and the used steel materials can also be recycled, saving costs and reducing construction waste.
2. Fast construction Compared with traditional buildings, light steel structure prefabricated buildings have simple processes. When building steel structure houses, large machinery is used instead of manpower, saving labor costs, saving time and effort. During the construction process, it can avoid the error rate and quality defects, shorten the construction period, and improve the construction efficiency. Because the precision of steel structure components is high, they are all operated by mechanization, which can effectively avoid things during workers’ operations, ensure quality, and have high safety.
3. Strong seismic performance The building material of steel structure houses is steel. In the event of an earthquake, its safety performance is several times that of ordinary houses. It absorbs energy very well and can better ensure that the house does not collapse and improve safety. The reason for the strong seismic performance is due to the large toughness of steel, which can resist earthquakes above level 8. Steel structures mainly use alloys as the main materials, which can effectively reduce labor in transportation and effectively save costs and reduce costs on costs.
4. Flexible space The difference between steel structures and concrete in terms of structural form is not big, but the difference in building materials is still very big. The compressive strength of steel is very high, and it can be applied to some buildings with larger spans, thereby meeting the space needs of different industries. The wall of the steel structure serves as a filling wall. In terms of layout structure, the steel structure is simpler and more flexible than concrete.

Development Prospects of Prefabricated Buildings

1. Application of fire and corrosion prevention Steel structure prefabricated buildings have very good performance in fire and corrosion prevention. Residential steel structures may corrode under normal indoor conditions, but they are also within a controllable range and do not affect the safety of the structure. In the current technology, when building steel structure buildings, anti-corrosion coatings are generally no longer used. The fire problem of steel structures can also be made safer and more reliable through packaging treatment.
2. Development of steel Since the reform and opening up, China’s economic level has been continuously developing, and China’s steel output has also been increasing year by year. In recent years, China’s total steel output has always maintained the world’s first place. China’s steel companies already have enough strength to produce on a large scale. With the continuous increase in domestic steel output, it has provided great help to the issue of fully developing steel structure prefabricated residences and promoted the further development of enterprises.
3. Technological development The first session of the 14th National People’s Congress of the People’s Republic of China and the first session of the 14th National Committee of the Chinese People’s Political Consultative Conference in 2023. The first session of the 14th National People’s Congress was held in Beijing on March 5, 2023. The first session of the 14th National Committee of the Chinese People’s Political Consultative Conference was held in Beijing on March 4, 2023.
4. Comfort of living The comfort of living in steel structure public buildings is relatively qualified. The most discussed is the densely populated residential area. Due to the immature technology of building enclosure and technology, there will be certain problems in quality. However, these can be improved later.
5. Government support At the same time, it also needs the support of the government, strengthens the promotion of the steel structure prefabricated building industry, formulates corresponding incentive policies, establishes a corresponding legal system, invests in efforts, accelerates the popularization of steel structure prefabricated buildings, and promotes the development of steel structure prefabricated buildings.

Steel structure prefabricated buildings have become the focus of enterprise development due to their unique characteristics, and have become an inevitable trend in the development of construction in our country. The future road is bright, but there are still many problems in technical conditions, and a complete technical system and management model need to be established. In terms of policy, we strongly support the development of the light steel structure prefabricated building industry and promote the development of China’s steel structures.
