Steel gates are commonly used water blocking and sealing equipment in water supply and drainage engineering, water conservancy, and hydropower engineering. They are composed of door frames, gate plates, sealing rings, and adjustable wedge-shaped pressure blocks. After long-term wear and tear, the sealing surface of the steel gate can be adjusted by wedge-shaped pressure blocks to ensure normal operation. The steel gate (steel gate) is made of high-quality steel plate as the substrate, and is coated with rubber water stop and anti-corrosion methods for surface sandblasting, rust removal, and hot spraying of zinc. The steel gate has a reasonable and sturdy structure, strong wear and corrosion resistance, and reliable performance; Easy to install, adjust, use, and maintain.
