立體鋼閘門是水利、電力工程普遍使用的一種水工產品。在工程中起到阻攔水流的作用，以利于后續設備或其他任務的正常運轉。本公司消費的鋼閘門有立體滑塊式鋼閘門，立體定輪式鋼曾用名。本公司消費的閘門與閘槽配合運用，能到達開關自若、密封功能好，每米長度的滲水量不超越0.03知/秒該閘門具裝置運用方便，止水功能好，防腐功能強等優點。
1、立體滑塊式鋼閘門：該閘門由門葉框架、橡膠水封、鎖定梁、滑塊等組成。該閘門除了密封止水外，左右兩端沒有鎖定梁，當須檢修時，將閘門支撐在閘槽上，滑塊采用含油尼龍，即耐腐蝕且磨擦系數爲鋼制的三分之一。

Plane steel gate is a kind of hydraulic product widely used in water conservancy and electric power engineering. It plays a role of interception flow in engineering, so as to facilitate the normal operation of subsequent equipment or other work. The steel gate produced by our company has a plane sliding block type steel gate, and the plane wheel type steel has been used. The gate manufactured by our company can be used in conjunction with the sluice groove to achieve the advantages of easy switching, good sealing performance, less than 0.03 knows/seconds of water seepage per meter length, easy installation and use, good water-proof performance and strong anti-corrosion performance. 1. Planar slider type steel gate: The gate is composed of gate blade frame, rubber water seal, locking beam, slider and so on. The gate has no lock beams at the left and right ends except for sealing water. When it needs to be repaired, the gate is supported on the groove. The slider is made of oily nylon, which is corrosion resistant and has friction coefficient of one third of steel.
