The company has the strength to produce all kinds of prestressed projects such as railways, highways and urban subways, and can undertake the construction of bridges with single span 100 meters and below. It has rich on-site construction experience and can produce concrete products10.5 million cubic meters all year round. The products produced by the company can be transported to all parts of the country by taking advantage of the railway transportation advantage connected by the 24-kilometer special railway line of Beijing-Guangzhou Railway and the road transportation advantage 3 kilometers away from Beijing-Shijiazhuang Expressway.
Over the past 50 years, it has participated in the construction of national key railway projects such as Li Zhan, Xia Ying, Baolan, Guikun, Cheng Kun, Lan Xin, Yanshi, Daqin, Houyue, Jingjiu, Qinshen Passenger Dedicated Line, Southwest Railway, Harbin Railway Hub, Wuhan-Guangzhou Passenger Dedicated Line, Beijing-Tianjin Intercity Rail Transit Project, Guangzhou-Shenzhen Passenger Dedicated Line, Beijing-Shanghai High-speed Railway, Shiwu Passenger Dedicated Line and Shanghai-Kunming Passenger Dedicated Line. It has contributed to the construction of Beijing Fifth Ring Road, Sixth Ring Road, Taijiu Expressway, Shihuang Expressway, Jingcheng Expressway and Beijing Metro Batong Line. It has provided high-performance concrete products such as high-quality segments and box culverts for the Nanjing Yangtze River Crossing Tunnel, the largest tunnel in China with world-class technology. Since 20 10, we have provided shield segments for Beijing Metro Line 6 and Line 8, with an annual output of over 7,000 segments. Since 2005, we have provided trapezoidal sleepers for Beijing Metro Line 4, Line 6, 10, Shanghai Metro, Shenzhen Metro and other subway projects. It has contributed to the subway construction in Beijing and other cities.
The company was named as "R&D Base" by China Railway Construction Association and Railway Equipment Development Center, and obtained the certificate of "Enterprise Technology Center" in Beijing. Jointly developed the first 24-meter double-line simply supported box girder in China with the scientific research department of the Ministry of Railways; Successfully completed the production and test of the first simply supported continuous beam of Beijing-Shanghai high-speed railway in China, which provided technical reserves for the construction of Beijing-Shanghai high-speed railway; Successfully developed and produced segmental beams of Beijing Sifeng overpass; Jointly developed with Beijing Holding Co., Ltd., Changsha University of National Defense Technology and other units the first medium and low speed magnetic levitation test line in China; The development and production of supporting blocks, capacitor sleepers, step sleepers, type I and type II ballastless track slabs have filled the gaps in China. Successfully developed the first domestic double-line simply supported box girder with a hole speed of 350 km/h and 32 m; The "Manufacturing Technology of Ballasted Turnout Sleeper for Passenger Dedicated Line" and "New Concrete Building Materials for Ballastless Track of High-speed Railway" developed by the company have passed the appraisal in Beijing, and experts agree that both technologies have reached the domestic leading level.
Since the restructuring in 2002, the company has accumulated more than 150 scientific and technological achievements, with more than 10 new products put on the market every year and 12 patents, forming a product structure of "new products emerge one after another and old products are constantly updated".
