The galvanized high-pressure cleaning machine gun barrel rear section is a high-performance component designed for high-pressure cleaning equipment and is widely used in high-pressure water cleaning operations such as industrial cleaning, automobile maintenance, building cleaning, and oil field pipeline cleaning. The galvanizing treatment effectively isolates the metal body from erosion by oxidants and moisture by attaching a layer of zinc coating to the metal surface, significantly improving the corrosion resistance. The galvanized surface also has anti-ultraviolet and anti-oxidation properties, allowing the cleaning machine gun rod rear section to maintain good performance in long-term outdoor or high-temperature environments. The galvanized gun rod rear section has a smooth surface and is resistant to pollution, which can effectively prevent the adhesion of scale, dirt or chemicals. When cleaning, just wipe it to keep the surface clean.
