This site intends to present technical proposals on hydraulic steel structures such as hydraulic gates,
　intake and discharge equipments, silt/sand dischargers etc. which are provided harbour entrances, docks
　and locks along waterways, or dams, weirs, floodgates and power stations on rivers, or irrigation systems.

PROPOSAL９　【OTHER HYDRAULIC STEEL STRUCTURES】

　Although there is no technology for hydraulic steel structures other than storm gates, draw-off gates, silt/sand discharge gates, emergency discharge gates and lock gates which satisfies the selection criteria for technical proposal, proposals can be made according to customer's requests. Details are as follows.
