钢闸门是给排水工程、水利、水电工程中常用的拦水、止水设备，由门框、闸板、密封圈及可调式锲型压块等部件组成。钢闸门久用磨损后，其密封面可通过锲型压块的调整来保证正常工作。
Steel gate is a common water-retaining and water-stopping equipment in water supply and drainage engineering, water conservancy and Hydropower engineering. It consists of door frame, gate plate, sealing ring and adjustable tine-shaped pressing block. After wear and tear of steel gate for a long time, the sealing surface of steel gate can be adjusted by tine pressing block to ensure normal operation.
钢制闸门以优质钢板为基材，采用橡胶止水、防腐方式为表面进行喷沙除锈及热喷锌，钢闸门具有结构合理坚固、耐磨耐蚀性强、性能可靠；安装、调整、使用、维护方便等特点。耐久性：轻钢结构全部采用冷弯薄壁钢构件体系组成，钢骨采用超级防腐高强冷轧镀锌板制造，有效避免钢板在施工和使用过程中的锈蚀的影响，增加了轻钢构件的使用寿命。结构寿命可达30年。
Steel gates are made of high-quality steel plates, and are sandblasted, rusted and hot-sprayed zinc on the surface of rubber water-proof and anti-corrosion. The steel gates have the characteristics of reasonable structure, strong wear resistance and corrosion resistance, reliable performance, convenient installation, adjustment, use and maintenance. Durability: All light steel structures are composed of cold-formed thin-walled steel members. Steel frames are made of super-anticorrosive high-strength cold-rolled galvanized steel sheets, which can effectively avoid the influence of steel plate corrosion during construction and use, and increase the service life of light steel members. The service life of the structure can reach 30 years.
