CHONGMING, SHANGHAI (June 18, 2026) — As the final concrete mixer truck departed, the reconstruction of Yongwei Road Bridge—a key transportation and livelihood project in Shuxin Town, Chongming District, Shanghai—achieved a major milestone. The project successfully completed its bridge deck paving and high-standard casting for core structural nodes.

As the material supplier of high-performance reinforced solutions, Hubei Qiandao New Material Co., Ltd. (“Hubei Qiandao”) provided its independently developed high-strength steel fiber products. The successful application injects robust “tech genes” into this vital bridge connecting local rural communities.

Weaving a Better Transportation Network: New Life for Yongwei Road Bridge

As a key public welfare project aimed at improving the rural road network and enhancing regional traffic capacity in Chongming District, the original Yongwei Road Bridge had suffered from years of service. It was no longer able to meet the growing travel demands of residents and heavy agricultural transport, posing potential safety hazards. The reconstruction required not only doubling the bridge’s load capacity, but also setting rigorous standards for crack resistance, wear resistance, and long-term durability.

Located at the mouth of the Yangtze River, Chongming Island presents a humid, salt-fog environment that severely challenges the anti-corrosion and anti-seepage properties of concrete structures. Meanwhile, frequent heavy traffic on rural roads creates a major headache for construction teams: preventing early cracking and spalling on the bridge deck caused by repeated vehicular loads.

Harnessing “Qiandao Strength”: 3D Mesh Skeleton Reshapes Concrete Genetics

To overcome these technical bottlenecks at the source, the construction team conducted rigorous technical evaluations and introduced Hubei Qiandao’s high-strength hooked-end steel fibers across the bridge deck paving and core load-bearing components.

Distributed in a 3D random orientation within the concrete, these short, high-strength steel fibers act as tens of thousands of “micro-rebars” embedded deep within the matrix.

  • Mechanical Anchoring Locks Micro-Cracks: Thanks to the unique hooked-end design, Hubei Qiandao’s steel fibers provide exceptional anchorage within the concrete. When micro-cracks occur due to thermal changes or vehicle loads, the high tensile strength of the fibers “pulls” the cracks together, preventing micro-cracks from developing into macro-cracks.
  • Enhanced Toughness Against Heavy Loads: Compared to conventional brittle concrete, steel fiber-reinforced concrete offers multi-fold improvements in impact resistance and fatigue life. It effectively handles thermal stress caused by severe seasonal temperature swings, ensuring the bridge deck stays durable under heavy traffic for decades to come.

“Fibers Over Rebars”: Streamlined Construction Accelerates Project Timeline

Beyond superior physical performance, the addition of Hubei Qiandao steel fibers delivered immediate cost and time efficiency to the job site. In specific areas of the bridge deck, the outstanding mechanical properties of the fiber-reinforced concrete allowed the engineering team to partially replace complex traditional secondary rebar mesh tying.

“In the past, manual rebar tying was time-consuming, labor-intensive, and extremely tedious to execute on the bridge deck,” noted the project manager. “By using Hubei Qiandao’s steel fiber solution, the materials are mixed uniformly directly into the concrete for integrated pouring. This eliminated significant manual labor, shortened the construction time for this key node by nearly one-third, and completely removed safety risks caused by uneven rebar protection layers. This is crucial for enabling local villagers to use the bridge as early as possible.”

Green Construction Paints an Ecological Backdrop for Chongming

As a national ecological island, Chongming District enforces strict environmental standards for all infrastructure development. Through deep material optimization, Hubei Qiandao’s steel fiber technology enabled a thinner deck design without sacrificing strength. This indirectly reduced overall consumption of cement and coarse rebars, perfectly aligning with Chongming’s vision of “Green Infrastructure and Low-Carbon Ecology.”

“Although the Yongwei Road Bridge in Shanghai Chongming serves as a ‘capillary’ project for rural traffic, it directly impacts the safety and daily lives of thousands of residents,” said a representative from Hubei Qiandao New Material Co., Ltd. “Its quality standards are no less stringent than those of major river-crossing bridges. Hubei Qiandao always upholds ‘Quality is Life.’ In the future, we will continue to focus on high-performance fiber composite materials, providing greener and higher-quality products to support high-quality upgrades for urban and rural infrastructure.”

Looking Ahead

With the successful completion of the deck pouring, the Yongwei Road Bridge has officially entered the curing and auxiliary facility construction phase. Once completed and opened to traffic, the bridge will greatly facilitate travel in Shuxin Town and surrounding areas, laying a solid, smooth foundation for Chongming’s rural revitalization and ecological development.
