Steel structure bridge

1. High strength and lightweight: Steel has much higher strength and stiffness than other building materials such as concrete and wood. This enables steel structure bridges to withstand greater loads while maintaining structural stability and safety. Steel has a relatively low density and light weight, which can reduce the overall load on bridges and lower the requirements for foundations and supporting structures

2. Fast construction speed: The components of steel structure bridges are usually prefabricated in factories and then transported to the site for assembly. This prefabricated construction method not only ensures the stability of quality, but also greatly shortens the construction period. The transportation and assembly of prefabricated components reduce on-site construction time, minimize interference with traffic, and reduce safety risks at the construction site

3. Corrosion resistance and seismic performance: Modern steel structural materials undergo special treatments such as hot-dip galvanizing and spray anti-corrosion coatings, which can effectively resist corrosion factors in the atmosphere. The ductility and toughness of steel give it significant advantages in earthquake resistance, as it can effectively absorb and dissipate energy under extreme conditions, reducing structural damage

4. Strong adaptability: Steel structure bridges are suitable for various complex terrains and climatic conditions. The plasticity and toughness of steel enable it to adapt to the needs of different spans, geometries, and terrain conditions, making it particularly suitable for large-span bridges such as cable-stayed bridges and suspension bridges‌‌
