The urban pedestrian temporary steel bridge is a mature and practical temporary traffic renovation solution independently supplied and technically supported by JSSJ widely applied in urban road upgrading, municipal construction and traffic diversion scenarios. Different from highway and sea-crossing bridges, this pedestrian steel bridge is tailored for dense urban traffic and pedestrian flow. Adopting standardized modular Bailey steel structure and Q345B high-strength steel materials, it features stable structure, high safety coefficient and excellent weather resistance. The surface is treated with professional anti-slip and anti-corrosion processes to adapt to complex urban environments such as rainwater erosion and frequent pedestrian traffic. With the advantages of rapid assembly, low site occupation and convenient disassembly, the bridge can quickly replace closed urban road sections and old pedestrian bridges
The Guangxi Qinzhou Longmen Temporary Steel Bridge
The Guangxi Qinzhou Longmen Temporary Steel Bridge is a critical auxiliary facility for the Longmen Cross-sea Bridge, a key mega infrastructure project in the Beibu Gulf Economic Zone. Located in the coastal waters of Qinzhou Longmen Port, adjacent to Maowei Sea and the Pinglu Canal estuary, the project confronts harsh marine environments with high salinity, humidity and tidal erosion. Adopting premium Q345B high-strength steel and integrated anti-corrosion processes including hot-dip galvanizing and epoxy zinc-rich primer, the bridge achieves strong resistance to seawater and atmospheric corrosion. Built with standardized modular Bailey bridge structures, the solution features high rigidity, heavy load capacity and rapid on-site assembly. It provides a stable offshore logistics and construction passage for the main bridge’s foundation construction, steel box girder hoisting and material transportation. This project fully demonstrates the company's reliable technical strength in marine temporary steel bridge engineering, effectively guaranteeing the smooth construction of the landmark Longmen Cross-sea Bridge.
