The explosive development of precast buildings in Hainan anchors the “value chain climbing”
In 2022, the construction area of precast buildings in Hainan Province will be about 28.6 million square meters, accounting for more than 60% of the new construction area, an increase of 25% over 2021.
As early as 2017, Hainan issued the Implementation Opinions on Vigorously Developing Fabricated Buildings.
At present, Haikou City, Sanya City, Chengmai County, Wenchang City, Ding’an County, Lingao County, Danzhou City, Wanning City and other cities and counties are all equipped with precast building production bases.
Guo Yanhong, member of the CPPCC Hainan Provincial Committee, also mentioned that the precast construction industry in Hainan is facing challenges such as unbalanced supply and demand of production capacity, imperfect industrial structure, low standardization and insufficient industrial talents.
.
Since last year, with the establishment and improvement of the precast building technical standard system, the precast interior decoration and the expansion of the application of precast components in municipal engineering have been continuously promoted, and the construction level and construction quality of precast buildings have been improved.
It is reported that this year, the Jinjingang precast building industrial park in Lingao County will continue to actively introduce precast building R&D, design, construction materials, component production, logistics, testing and other enterprises to accelerate the improvement of the precast building industrial chain.
However, in order to achieve this goal, the industry still faces constraints such as incomplete industrial chain, bottleneck in the development of industrial base, and low level of standardization.
In Hainan Free Trade Port, as one of the landmark projects of Hainan National Ecological Civilization Pilot Zone, the precast building area of the whole province has doubled continuously in the past four years.
In order to meet the requirements of the construction speed of the Free Trade Port, Hengkun New Materials has a maximum daily supply of wall panels of 1500 ㎡ per project.
Can you imagine that building a house is as simple as building blocks? Today, precast buildings, known as building houses like building blocks, are leading the new trend of green buildings.
The rapid development of precast buildings in Hainan benefits from the continuous improvement of relevant supporting policies, standard system and capacity layout and the implementation of relevant projects.

Hengkun New Materials, as the leading light partition board enterprise with the earliest investment layout, large capacity and strong supply capacity in Hainan Province, has built a north-south double production base in the Laocheng Economic Development Zone in Haikou, Hainan and Yacheng Science and Technology Park in Sanya, with a total annual capacity of 100000 cubic meters, and the product quality and performance are superior to the national standard (comprehensive unit weight<750kg/m ³, The compressive strength is more than 4.5 MPa), and has successively participated in such projects as Haikou Financial Center, International Energy Center, Wenli Anju House, Haikou Resettlement House, etc.
“Vigorously promoting precast buildings can significantly save resources and energy, reduce environmental pollution, improve labor productivity, and improve quality and safety level.” Guo Yanhong, member of the CPPCC Hainan Provincial Committee, analyzed that Hainan takes precast buildings as an important measure to promote the transformation and upgrading of the construction industry in Hainan, and is also one of the important supporting work of carbon peak and carbon neutrality in Hainan, The policy advantages of “zero tariff, low tax rate and simple tax system” of Hainan Free Trade Port have injected policy dividends into the development of precast construction industry.
The scope of precast buildings has also gradually expanded from government-invested hospitals, schools, stadiums and other projects to commercial office buildings, commercial houses and some bridges, post stations and other construction projects.
The embryonic form of the industrial chain has continuously improved the supporting policies, standard system and capacity layout.
“Hainan precast buildings have constraints such as incomplete industrial chain and bottlenecks in the development of industrial base, which need to be further improved.” Huo Juran, a member of the CPPCC Hainan Provincial Committee, pointed out that at present, standards and specifications such as the Calculation Rules for the Assembly Rate of Hainan precast buildings (revised in 2021), the Technical Standards for the Assembled Interior Decoration of Hainan Province, have been issued and implemented to promote the precast and precast decoration of vertical components, However, Hainan’s precast buildings still have problems such as incomplete upstream and downstream industrial support, insufficient industrial workers, and incomplete industrial chain.
has made great efforts to promote the construction and application of precast buildings in Hainan.
In simple terms, it is to divide and design the beams, columns, walls, stairs, balconies and other components of the building, produce them in a standardized way in the factory, and then transport various components to the construction site after prefabrication.
The precast interior decoration and vertical components of the main structure have not yet been popularized.
The industry pressed the “fast forward” button to build precast buildings in Hainan Province last year with an area of about 28.6 million square meters.
In 2022, Hainan issued another document in the field of precast buildings and issued the Opinions of the General Office of the People’s Government of Hainan Province on Further Promoting the High-quality and Green Development of Fabricated Buildings in Hainan, which put forward development goals more accurately and specifically, and guided relevant enterprises to reasonably layout industrial bases and product types, Accelerate the formation and aggregation of industrial chains.
Many industry insiders said that in recent years, the production capacity and design capacity of precast buildings in Hainan have been significantly improved.
In order to better serve enterprises, Lingao Gold Port Development Zone has put forward the service commitment of “introducing in the same year, acquiring land in the same year, starting construction in the same year, and putting into production in the same year”.
How to form a healthy and complete industrial chain? In recent years, the implementation of the standard system and the rational layout of production capacity have promoted the “manufacturing” to “intelligent manufacturing” of precast buildings in Hainan Province, which has made gratifying achievements, but the industry also faces some weaknesses and challenges in the process of development.
The workers accurately assemble these components like “building blocks”.
The total number of precast building production bases that have been put into operation or under construction in the province has reached 35.
The stable product quality and excellent installation management have been unanimously praised by the owner and the general contractor.
Hainan’s continuously optimized business environment is also an important factor to promote the rapid development of the industry.

Of course, the precast construction industry is not only showing vitality in Lingao.
According to the development plan of precast construction industry in Hainan Province, by 2025, the proportion of precast construction area in the new construction area in the province will reach more than 80%, and the added value of precast construction industry will reach 30 billion yuan.
