Precast building is a building that transfers a large number of on-site operations in the traditional construction method to the factory, processes and manufactures building components and accessories (such as floor slab, wallboard, staircase, balcony, etc.) in the factory, transports them to the construction site, and assembles and installs them on site through reliable connection.

According to the top-level, local rules and the consumption quota of precast construction projects, it is estimated that the cumulative market space of precast construction in China from 2017 to 2020 is about 2 trillion yuan, of which the cumulative market space of Beijing Tianjin Hebei, Yangtze River Delta and Pearl River Delta exceeds 850 billion yuan, accounting for about 40% of the country; From 2017 to 2025, the cumulative market space of precast buildings in China exceeded 6.8 trillion yuan.

The research data show that compared with the traditional method, the precast concrete construction project can reduce construction waste by 70%, save wood by 60%, cement mortar by 55% and water resources by 25%.

(data source: prospective industry research institute) Note: (1) the research data of relevant online articles are still in 2018-2019, which is not of great reference value.

According to network data, by 2019, precast buildings accounted for 13.4% of new buildings.

(data source: Chinanet) the relevant policies of the precast construction industry, the 14th five year plan for the development of the construction industry, specify that during the 14th Five Year Plan period, China should initially form a framework for the high-quality development system of the construction industry, improve the operation mechanism of the construction market, basically improve the project quality and safety assurance system, and greatly improve the level of industrialization, digitization and intellectualization of buildings, The green transformation of construction mode has achieved remarkable results and accelerated the transformation of the construction industry from large to strong.

(2) At present, the attention of market funds to the sector has an obvious upward trend, but the online research data is not very supportive to the sector, and may still have to rely on the trend of the real estate sector…

(data source: Chinanet) Research Report on precast buildings: by 2020, the market space of precast buildings in China will be about 2 trillion yuan, and by 2025, it will exceed 6.8 trillion yuan.

The planning is clear, the policy system and industrial system for the coordinated development of intelligent construction and new building industrialization are basically established, and the proportion of precast buildings in new buildings reaches more than 30%.
