Sluice gates brave the shifting tides
10/01/2023
Sluice gates are movable barriers that regulate water levels and flow rates in waterways. In a world of changing climates and increased flooding risk, these gates need to be taller and stronger than ever before. Thanks to their strength and corrosion resistance, molybdenum-containing duplex stainless steels are the ideal construction material.

Sluice gates are movable barriers that regulate water levels and flow rates in waterways. In a world of changing climates and increased flooding risk, these gates need to be taller and stronger than ever before. Thanks to their strength and corrosion resistance, molybdenum-containing duplex stainless steels are the ideal construction material.
Traditionally made of wood or metal, sluice gates make life possible in the world’s most populous places: along rivers or coastal regions, which are often vulnerable to flooding. The basic technology behind sluice gates is ancient- Sri Lankan society used them over 4000 years ago- but their refinement continues today. Some modern sluice gates use duplex stainless steel, which offers substantial benefits over other construction materials. The sluice gates at Mon St-Michel in Avranches, Slusssen in Stockholm and the Garda Damme in Gothnburg showcase how these gates conserve material, capital, and emissions throughout their service lives.
