In midsummer, the intelligent production line of Hexian Intelligent manufacturing base runs at a high speed, and the new lightweight high-performance bridge panel is orderly rolled off the line. Jianning West Road crossing river channel project, the company’s first single new material — fluidized solidified soil is about to start supply; The last span of G312 East extension project steel concrete composite beam was accurately lifted in place, and the whole line was realized… Since its establishment in 1995, Pudi Intelligent Manufacturing Technology Group Co., LTD., a subsidiary of Nanjing Transportation Group, has been deeply cultivating infrastructure and building materials for more than 30 years. It has promoted the transformation from a traditional concrete enterprise to a comprehensive transportation infrastructure intelligent manufacturing service provider by industrial upgrading and scientific and innovative research and development. The total order amount of prefabricated components has exceeded 800 million yuan in recent years, and the production schedule is scheduled to the end of 2027.
In the past, Pudi Group only relied on the single business of traditional commercial concrete, which was vulnerable to regional infrastructure fluctuations and low-price competition. Enterprises take the initiative to adjust their business ideas, while tapping into the potential to reduce costs, while expanding the market outward, and building a dual business pattern of “business mixed stable chassis, prefabricated components increase”.
In 2024, the unit cost per square volume decreased by nearly 12% year-on-year, and in 2025, it decreased by another 10%. By optimizing raw material procurement and reshaping the production process, the fine management fell into each process. In 2025, Ningxin Company will cooperate with state-owned enterprises in the Shangyuanmen River Crossing channel project, innovate the new mode of “station rental + processing”, lock long-term profits in advance, and effectively hedge the risk of market cycle.
In view of the difficulties of regional investment reduction and technical achievements difficult to land in the early stage of the new structure company, the company decisively adjusted its product strategy in the second half of 2024, created a “1+N” prefabricated product matrix, and took lightweight UHPC components as the core to simultaneously expand multi-category precast concrete products. The operation adjustment quickly reaped market returns. In 2025, it won nearly 400 million yuan of orders for large segments of Maanshan Hubei Road River crossing channel, and the foreign business accounted for 90%. Now, in the 250 mu intelligent manufacturing base in Hexian County, there are many production lines with independent intellectual property rights, such as automatic production lines of plate components, large-diameter shield segments and automatic box beam, which are running at full capacity. The total annual production capacity of the two bases exceeds 220,000 square meters. The intelligent production line supports enterprises to take orders across regions and get away from the limitations of the local market.
After the prefabricated component business has formed a stable revenue chassis, Puti Group will turn its attention to the green new material track, transform technology research and development into long-term competitiveness, and open up the second growth curve of the enterprise. “Together with the Highway Science Research Institute of the Ministry of Transport and the Nanjing Water Conservancy Research Institute, we continue to research solid waste utilization technology and replace cement with industrial solid waste, which not only responds to green and low carbon policies, but also can actually reduce production costs.” Group technical director introduced. Relying on the long-term production-study-research cooperation mechanism, the enterprise focuses on two key technologies: all-solid waste cementitious materials and UHPC core powder. At present, all-solid waste cementitious materials have completed laboratory verification, and each party can reduce the cost of commercial mixing by 7 yuan. UHPC composite core material has completed pilot test verification, and is accelerating to large-scale traffic engineering. The enterprise follows the cascade transformation idea of “R&D batch, reserve batch and application batch”, arranges special building materials such as lightweight concrete, iron sand concrete and fluidized solidified soil, and innovates the integrated service mode of “material supply + post-maintenance”. In June 2026, the new material plate successfully signed a contract for the fluidized solidified soil project of the West Jianning Road river crossing channel, and won the first commercial order of the plate, marking the official realization of the market order of the new material layout strategy.
At present, Puti Group holds 40 intellectual property rights such as invention patents and utility model patents, and has successfully been approved as a national high-tech enterprise, a provincial specialized and new small and medium-sized enterprise, and an engineering research center. Taking scientific innovation as the starting point, it promotes the business extension from traditional building materials to green new materials, and accelerates the conversion of old and new drivers.
