Stainless steel guardrails are one of the most widely used types of stainless steel products. For stainless steel composite pipe guardrails, due to their relatively stable physical and chemical properties, they generally do not undergo chemical reactions with any metals or non-metals, so they will not rust. If you purchase and use stainless steel composite pipe guardrails and find rust, it indicates that there is a quality problem with the product and it should be annealed. Why is that? We can conduct relevant analyses through the following several situations:

　　Stainless steel guardrails can prevent rust and provide a layer of zinc protective film for the metal. Conductive metal material repair, color enhancement and care agent. Safe and reliable dual protection, synthetic metal resin protective layer and cathodic protective layer, can resist harsh weather and is suitable for long-term outer protection of metals. It has an excellent resistance to the corrosion of salt and water. It adheres strongly to various metals and their alloys, can be directly sprayed without primer, is heat-resistant, not afraid of baking, and after drying, the coating can withstand high temperatures of approximately120℃. The anti-drying temperature can reach80℃Dry quickly. Economical and practical, one spray can prevent rust.

　　The anti-corrosion function of stainless steel guardrails is not only based on the zinc content in the zinc coating, but also affected by the size of the particles in the zinc layer. The smaller the zinc particles, the higher the density of the coating. When the coating quality is high, it is like a single layer100%High-temperature hot-dip plating. The function of these fine particles is to make the coating more compact, which not only can prevent corrosion but also can be less than or equal to prevent the volatilization of zinc components120μm(Vertical plane)The coating. Under normal usage conditions, the anti-corrosion time in the atmosphere can reach more than thirty years.
