by 1、 Survey on the Production Status of Prefabricated Building Components in Shanghai 1 General Overview of Prefabricated Building Components Factory in Shanghai With the promotion of prefabricated building projects, the capacity of prefabricated building components in Shanghai has continued to increase, and the capacity of prefabricated building components in Shanghai has increased rapidly.
With the large-scale implementation of projects, the confidence of industry units has been greatly boosted, and the pace of transformation and development has been actively accelerated.
Many enterprises have set up prefabricated building research and development centers.
The production capacity has increased from 1.8 million square meters of prefabricated building components by the end of 2014 to nearly 5 million square meters by the end of 2015, and exceeded 12 million square meters by the end of 2016.
As of May 2017, the design capacity has reached 15 million square meters.
Under the background that the Ministry of Housing and Urban Rural Development cancelled the market access of prefabricated component manufacturers, it actively explored the management mode of combining administrative supervision and industry self-discipline.
The Notice of Shanghai Municipal Commission of Housing and Urban Rural Development on Printing and Distributing the Provisions of Shanghai Municipality on the Supervision and Administration of the Use of Construction Engineering Materials (HJG [2015] No.
726) clarified that the industry association should register the component manufacturers and their product flows, Give full play to the role of self-discipline management in the industry.
Reasonably guide the production capacity of prefabricated components, timely release the construction plan of Shanghai prefabricated buildings, the layout of existing prefabricated component plants and production capacity data, and ensure the supply and demand balance of the prefabricated component market in Shanghai.
As of June 2017, there were 52 registered enterprises, including 29 local enterprises, accounting for 56% of the total, 23 foreign enterprises, accounting for 44% of the total, including 13 enterprises in Jiangsu Province, accounting for 25% of the total, and 10 enterprises in Zhejiang Province, accounting for 19% of the total.
The capacity of prefabricated components can basically meet the needs of projects under construction in this city.
In terms of auxiliary materials (sleeves, grouting materials and connectors) for prefabricated components, as of 2016, there were 20 sleeve, grouting materials and connectors enterprises in Shanghai.
Among them, there are 3 sleeve enterprises, 3 grouting material enterprises and 2 connector enterprises in the city.
There are 8 sleeve enterprises, 5 grouting material enterprises and 9 connector enterprises from other provinces and cities.
Figure 2 and Figure 3 respectively show the distribution plans of local and foreign enterprises of prefabricated components filed in Shanghai.

Introduction to Typical Assembled Prefabricated Components and Supporting Research Enterprises in Shanghai The research group investigated typical prefabricated components in Shanghai based on the research outline.
The research enterprises include prefabricated component enterprises such as Shanghai Urban Construction Materials Harbor Assembled Building Parts Production Project, Baoye Residential Engineering Qingpu Prefabricated Component Production Project, etc, The company profile is as follows: 1 Shanghai Urban Construction Materials Port side Assembled Building Parts Production Project Tunnel Stock Shanghai Urban Construction Materials is a sole proprietorship enterprise with an annual sales volume of more than 2 billion yuan, based on the R&D, production and sales of commercial concrete and new building materials, supported by the e-commerce of green, environment-friendly and new energy-saving building materials, and led by the investment in science and innovation cultivation industry.
At present, it has the highest qualification for the production of prefabricated concrete components and commercial concrete in China.
The whole process of production and sales is controlled by ISO9001 quality assurance system, ISO14000 environmental management system and OHSAS18000 occupational health and safety management system.
The company has a municipal enterprise technology center, and is a high-tech enterprise in Shanghai, a civilized unit in Shanghai, a winner in concrete components in Shanghai, and an outstanding company in the meritorious service competition for key projects in Shanghai.
The company has eight specialized commercial concrete companies, four specialized branch companies for the production and processing of prefabricated components, the most advanced PC automated production line in China at present, and has mastered the advanced production process of various prefabricated concrete components.
The main products include ready mixed commercial concrete, ready mixed commercial mortar, dry powder mortar, finished concrete wallboard (PC board), bridge deck, tunnel segment, square pile, high-strength reinforced concrete protective layer positioning piece and other municipal and building concrete and products, which have been recognized by PCI Concrete Association of the United States and JIS Standard Testing Center of Japan respectively, and are the first concrete prefabricated component enterprise in China to obtain the certification qualification of PC Association of Japan.
The company’s “PC precast concrete components” and “desulfurization gypsum inorganic thermal insulation mortar” won the title of famous and excellent products in Shanghai building materials industry.
The company has established a strategic partnership with Shanghai Vanke Real Estate Co., Ltd.
to produce PC boards in China, becoming the first designated PC board manufacturer.
The Lingang Branch of Urban Construction Materials is currently building a prefabricated component production line with international advanced level, with an annual design capacity of 1.5 million square meters.
It has been selected as one of the “2016 Science and Technology Project Plan Assembled Building Science and Technology Demonstration Project” by the Ministry of Housing and Urban Rural Development, and “2016 Top Ten Enterprises in the Production of Prefabricated Concrete Components for Housing Construction” by the Prefabricated Concrete Component Branch of China Concrete and Cement Products Association.
The main products include prefabricated ordinary exterior wall panels, laminated floors, sandwich insulation exterior wall panels, etc.
The main demonstration contents are: optimizing the imported fully automatic PC production line in Finland, which can produce special-shaped components and improve production efficiency; Realize component information management through RFID chip implantation.
2 Baoye Housing Industry Qingpu Prefabricated Component Production Project Baoye Housing Industry Qingpu Prefabricated Component Production Project was undertaken by Shanghai Baoyue Housing Industry Co., Ltd.
and was selected as the “2016 Science and Technology Project Plan Assembled Building Technology Demonstration Project” by the Ministry of Housing and Urban Rural Development.
