Seismic   Anti-Corrosion Q355B Bridge Steel Box Girder

prodnct deecrlption

  A steel structure bridge made of Q355B high-strength bridge steel, specifically designed for modern transportation infrastructure. Steel has excellent welding performance and low-temperature toughness, making it suitable for complex stress environments in bridges. The large-span design can reach up to 1000 meters, meeting the needs of crossing seas and rivers. Seismic and wind resistant design ensures the safety of bridges in extreme weather conditions. Reinforced anti-corrosion design for the rainy and humid climate in Southeast Asia; optimized thermal deformation control for the high-temperature and arid environment in the Middle East.
