How is the anti-corrosion performance of guard fence?

As an important hardware building material, guard fence is widely used in many fields such as construction, transportation, agriculture, and breeding. Its main function is to provide safety protection to prevent people from falling, objects from falling, or foreign objects from intruding. However, guard fence is exposed to the outdoor environment for a long time and will be eroded by wind, rain, sun, rain, and chemicals. Therefore, anti-corrosion performance has become an important indicator to measure the quality of guard fence.The anti-corrosion performance of guard fence mainly depends on its material and surface treatment process. Common guard fence materials include stainless steel, galvanized steel, aluminum alloy, etc. Stainless steel is known for its excellent corrosion resistance. It can maintain its original strength and toughness for a long time in harsh environments. It is the preferred material for manufacturing high-end guard fences. Galvanized steel improves its anti-corrosion performance by coating a layer of zinc on its surface. The zinc layer can effectively prevent oxygen and water vapor in the air from contacting the substrate, thereby achieving the purpose of anti-corrosion. Aluminum alloy guard fence has the characteristics of light weight, high strength, and corrosion resistance, and is suitable for various complex environments.In addition to the choice of materials, the surface treatment process also plays a vital role in the anti-corrosion performance of the guard fence. Common surface treatment processes include hot-dip galvanizing, cold-dip galvanizing, and plastic spraying. Hot-dip galvanizing is to immerse the steel in molten zinc liquid to form a dense zinc-iron alloy layer on its surface. This process has the advantages of strong anti-corrosion performance and good adhesion. It is the mainstream method of anti-corrosion treatment for guard fences. Cold galvanizing is to electroplating the zinc layer on the surface of the steel at room temperature. Although the anti-corrosion performance is slightly inferior to hot-dip galvanizing, the cost is lower and it is suitable for some occasions where the anti-corrosion performance is not high. Plastic spraying is to spray plastic powder on the surface of the steel, and form a protective film after high-temperature curing. This process not only has anti-corrosion function, but also improves the beauty and durability of the guard fence.In actual applications, the anti-corrosion performance of the guard fence is also affected by environmental factors. In a humid, rainy, and foggy environment, the guard fence is more susceptible to corrosion, so it is necessary to choose materials and surface treatment processes with stronger anti-corrosion performance. At the same time, during the installation and maintenance process, it is also necessary to avoid scratches, impacts and other damage to the guard fence to avoid affecting its anti-corrosion performance.In summary, the anti-corrosion performance of the guard fence is an important guarantee for its quality and service life. When choosing a guard fence, it is necessary to reasonably select the material and surface treatment process according to the actual use environment and needs to ensure that the guard fence has sufficient anti-corrosion performance. At the same time, during use, it is also necessary to strengthen maintenance and care, and promptly discover and deal with potential corrosion problems to extend the service life of the guard fence.
