The selling points of cast iron sluice gates focus on material characteristics, performance advantages, and engineering adaptability. The core selling points are summarized as follows:

1. High-strength cast iron material, pressure-resistant and wear-resistant

? Made of gray cast iron or ductile iron, with high density and strong hardness, capable of withstanding high water pressure (suitable for high-head conditions). It also offers outstanding resistance to water flow erosion and sediment wear, making it ideal for water environments containing impurities (such as irrigation channels and wastewater treatment plants).

2. Tight water stoppage and durable sealing

? The contact surfaces between the frame and gate leaf are precision-machined and paired with rubber water seals or metal sealing structures, ensuring excellent water stoppage. The low deformation of cast iron material maintains good sealing over long-term use, reducing the risk of leakage.

3. Strong corrosion resistance, suitable for harsh environments

? Cast iron inherently possesses certain corrosion resistance, and its surface can be further treated with anti-corrosion measures (such as rust-proof paint or thermal spraying zinc). It offers a long service life in damp, acidic, alkaline, or seawater environments, making it suitable for
