[Industry information] Penetration rate of prefabricated buildings, newly started building area, market structure and industry development


Classification.

The three types of structures are applicable to different building types.

The second echelon: private enterprises, mainly including Yuanda Housing and Engineering Co., Ltd., Quanzhu Co., Ltd., and Jianghe Group.

Components and parts that should have been cast in place, such as columns, plates, beams, etc., are produced and shaped in the factory, transported to the site for assembly, made nodes, and finally cast in the site to combine these components and parts to form a complete building.

Starting from their original businesses, these enterprises participate in prefabricated construction projects, and have strong production and processing capabilities for prefabricated component products.

During the 14th Five Year Plan period, China will strive to achieve carbon peak by 2030 and carbon neutrality by 2060.

From the perspective of construction period and cost, the construction period of steel structure and concrete structure is short and the construction cost is low, among which, the finishing of 300m steel structure only takes about 60 days.

It is estimated that with the continuous improvement of industrial penetration and recognition, the newly started assembly area still has a large growth space.

As far as the market structure is concerned, the proportion of newly started prefabricated building structures in China is still mainly concrete structures and steel structures., The data shows that the proportion of 2021 concrete structure and steel structure has decreased slightly, reaching 67.7% and 28.8% respectively, while other structures have increased.

The development process of prefabricated buildings in China is slightly slower than that in foreign countries, which can be roughly divided into four stages: the initial stage, the peak stage, the stagnation stage and the new stage.

Green and low-carbon prefabricated buildings are also leading the transformation and development of the construction industry.

According to different structural characteristics, prefabricated buildings can be divided into concrete structures, steel structures and wood structures.

From the perspective of industrialization degree and environmental protection performance, the steel structure has the highest industrialization degree, and the wood structure uses raw materials that are environmentally friendly.

Data source of domestic policies related to overall and regional prefabricated buildings: public data collection III.

Penetration rate of overall buildings and prefabricated buildings decreases with the development of China’s real estate industry, and the overall newly constructed area shows a trend of continuous small decline.

With the same fashion matching buildings, the proportion of the newly started area will continue to rise, which has reached 15% by 2021, due to their convenience, reusability and significant cost reduction.

Assembled competition pattern 1.

Data source of prefabricated building structure system: the concrete structure has excellent compressive strength, fire protection, corrosion prevention, sound insulation and other characteristics, and the seismic degree is poor after public data collection; The steel structure has the best seismic performance and good insect resistance, but it is easy to conduct heat and has poor fire resistance; Wood structures have strong seismic resistance, relatively high compression resistance and sound insulation, and the rest have the worst performance, especially the wood structure main material resources are scarce.

These enterprises are mainly integrated component enterprises.

Each of the three structures has its own advantages.

Source of information on the competitive echelon of the prefabricated construction industry: In terms of the changes in the number of prefabricated component enterprises in the public data sorting and subdivision type, the industrial demand continues to grow under the policy background, and the number of enterprises entering the industry continues to grow, with the highest number of concrete enterprises occupying the main market share, growing from 724 in 2018 to 1261 in 2021..

These enterprises are mainly comprehensive large-scale construction enterprises, Transform from traditional construction business to participate in the operation of prefabricated construction business.

Data source for the development history of prefabricated buildings: public data sorting.

Since 2019 to 2021, the newly started area has continued to decline.

Market concentration At present, the market participants of prefabricated buildings are mainly divided into two echelons: the first echelon: large state-owned enterprises, mainly including CSCEC, Ningbo Construction Engineering, Shanghai Construction Engineering, Huajian Group, China Railway Assembly, etc.

Current situation of prefabricated building industry 1.

It has a deep foundation in architectural design and construction, and actively develops and builds production lines for PC components and steel components, covering a wide range in the prefabricated building industry chain.

The construction period of timber structure is long, leading to the highest construction cost.

All provinces and cities responded to the important call and issued corresponding documents one after another.

Concrete structures are generally used in multi-layer and small high-rise buildings; Steel structure is applicable to high-rise and super high-rise buildings with high seismic requirements; Wood structure is mainly applicable to luxury villas.

Source of comparative data on advantages and disadvantages of various types of prefabricated interior decoration: Public data sorting II.

In the first half of 2022, the newly started area will be 1.971 billion square meters, down 12.5% compared with the same period in 2021.

With the promotion of the government plan, a large number of market demands and the continuous standardization of the prefabricated building industry environment, the penetration rate of domestic prefabricated buildings will be significantly improved.

Background of prefabricated building policy In March 2019, the Ministry of Housing and Urban Rural Development officially released the Technical Standards for Fabricated Interior Decoration (Draft for Comments) to help the development quality of prefabricated interior decoration.

Data shows that the newly constructed area of housing in China has continued to grow in 2018 and before, As the overall housing price rises, the number of people with actual purchasing power continues to decline.

As for newly started prefabricated construction area in China, the overlapping ownership under cost advantage continues to rise, and the newly started prefabricated construction area in China continues to rise, according to the data, The newly started prefabricated building area in China will increase from 114 million cubic meters in 2016 to 740 million cubic meters in 2021, with a compound growth rate of 45%.

1、 Overview of Fabricated Building Industry Fabricated building refers to a building formed by assembling and connecting factory produced components at the construction site.
