With the large-scale application of long-span bridges, the large-scale use of steel structures is an inevitable trend in the future development of transportation infrastructure.
The bridge construction cost should comprehensively consider various factors such as construction cost, safety and durability, management and maintenance.
The steel structure bridge has a lighter self-weight, which saves the cost of the substructure. At the same time, the construction speed is faster and the construction period is shorter. The problem of insufficient corrosion resistance of steel structures can be solved by applying long-term high-performance anti-corrosion coatings and using weathering steel.
DIN 17102 WStE380 steel plate is a steel commonly used in bridge construction. More details are as following :
