London is potentially vulnerable to flooding due to the rising high-water level and the risk of a surge tide during a severe storm. In order to protect the city, a flood barrier was built.
The iconic Thames River Barrier, which became operational in 1982, is the second largest movable flood barrier in the world stretching 523 metres across the river Thames. The barrier comprises four piers of wooden structure clad in maintenance free 0.3mm thick type 316 (1.4401) stainless steel sheet. This particular grade with 2% molybdenum has resistance to corrosion, even in brackish waters, and makes stainless steel the perfect choice to ensure floods are kept at bay.
