A hinged floating gate that completely resolves the problem of clogging!
The "U Gate" is a permanently open flap gate designed to overcome the shortcomings of conventional non-powered automatic gates, such as clogging, and to ensure safe and reliable closure during floods. With a simple structure, the gate hangs in an inverted L shape, pivoting around a hinge located at the tip that extends from the riverbank during normal water levels. 【Features】 - No operation or power required, which avoids operational errors and saves maintenance costs. - Remains open during normal water levels, allowing the movement of fish and crustaceans without obstruction. - Can be manufactured at a slightly lower cost than floating structure gates or flap gates. - The gate body is made of aluminum, and other components are made of stainless steel, eliminating concerns about corrosion. *For more details, please download the PDF or feel free to contact us.*
