Silvery Dragon Co., Ltd. is a full range manufacturer of prestressed steel products in the world with a large production capacity, and it is an innovative enterprise in pre-stressed steel research and development with independent technological innovation and industry influence. At present, there are five prestressed steel production bases, including Tianjin headquarters, Hejian branch, Hejian Baozelong, Liaoning Benxi, and Silvery Dragon Xinjiang, with an annual production capacity of over 600,000 tons. The main products include: PC Wire, PC Bar, PC Strand, Ultra-high-strength Strand, Unbonded PC Strand, Prestressed galvanized (aluminum) Wire and Strand for bridge cables, High-strength Strand for nuclear power plant safety shells, High-strength and weather resistant Strand for ultra-low temperature LNG/LPG, Prestressed flexible large-span suspension photovoltaic support galvanized Strand and accessories, Unbonded PC Strand for wind power concrete towers, PC wire for PCCP pipelines, PC spiral rib wire for railway sleepers, and fixed length twisted wire for high-speed rail track slab. Silvery Dragon products are applied to China "eight vertical and eight horizontal" high-speed railway routes such as the Beijing-Tianjin intercity railway, Beijing-Shanghai high-speed railway, Harbin-Dalian high-speed railway, Shanghai-Kunming high-speed railway, Beijing-Shijiazhuang-Wuhan high-speed railway, etc. Silvery Dragon has obtained product quality certification from multiple countries and exported to multiple countries and regions around the world. In recent years, newly developed High-strength prestressed galvanized, galvanized aluminum Wire and Strand for bridge cable have been used to make cable strand for stayed-cable and suspension bridges. The products have entered the ranks of major cable suppliers for kilometer level bridges, and performance has maintained a first-class level in the industry.
Based on years of experience in the research and development of key materials for track slab, the company has established a high-speed rail track slab research and development test base in Hejian City, Hebei Province. The base undertakes the research and development project of high-speed track slab from the China State Railway Group Technology Department, and jointly develops CRTS-III ballastless track slab with relevant units of the railway system. In the subsequent development, the production equipment and process of track slab have been improved, which has been highly recognized by relevant users and management units. The base continues to research and development and innovative products such as subway track slab and subway floating slab. At present, the company has multiple wholly-owned and joint venture production bases for track slab (sleeper), including Hebei Hejian, Anhui Huaibei, Tianjin Baodi, Shanghai Railway Wuhu, Jiangxi Ganzhou, and Guangdong Yangjiang as well as production and supply performance for high-speed railway track slab in Zhengzhou-Xuzhou, Beijing-Shenyang, Zhengzhou-Fuyang, Zhengzhou-Jinan, Beijing-Xiong'an, Ganzhou-Shenzhen, Beijing-Tangshan, Guangzhou-Zhanjiang, Xiong'an-Shangqiu, and other High Speed Railway.
At the same time, Silvery Dragon has developed a series of technologies such as automated tooling equipment and track informatization for track slab, and has successfully designed and developed major innovative products and technologies such as the CRSD2025 automated production line for track slab, high-precision moulds for concrete prefabricated components such as track slab and pipe segment, stress release and locking construction management system for seamless railway track, and track slab production informatization management system.
In response to China's green energy strategy, the company began extending its industrial chain to the field of new energy in 2018. Our main research and development products include High-strength Strand for nuclear power plant safety shells, High-strength and weather resistant Strand for ultra-low temperature LNG/LPG, Prestressed flexible large-span suspension support systems for photovoltaic power generation, Prestressed anchor systems for wind power concrete towers, and other high-quality products.
The headquarters of Silvery Dragon in Tianjin and the Hejian factory have taken the lead in constructing a green photovoltaic power generation project, which has achieved good comprehensive benefits since its operation. Hejian Baozelong Metal Materials Co., Ltd., a wholly-owned subsidiary of Silvery Dragon, has been approved for the 150MW centralized wind power generation project in Hebei Province in 2023.
Looking ahead to the future, Silvery Dragon will uphold the glorious mission of "Representing China to the world", carry forward craftmanship, attach importance to management, focus on research and development, and strive to develop more "specialized, refined, unique, and new" products, moving forward towards the aspiration of "Deeply respected and Industry leader".
