The main reason why steel channels are resistant to corrosion is because of the protective oxide layer that forms on their surface. This layer, also known as a patina, acts as a barrier between the metal and its surroundings, preventing direct contact and reducing the likelihood of corrosion. The formation of the patina occurs through a process called passivation, which happens when steel is exposed to oxygen in the air or water. Passivation assists in creating a stable and firmly attached layer of oxide that effectively inhibits the corrosion process. Additionally, steel channels can receive further protection against corrosion through different surface treatments like galvanization or coating with materials that are resistant to corrosion, such as zinc or paint. These treatments provide an additional layer of defense against moisture, chemicals, and other elements that cause corrosion. It is crucial to regularly maintain and inspect steel channels to prevent corrosion, as any damages or breaches in the oxide layer can expose the underlying metal and increase the risk of corrosion. In summary, the combination of the natural passivation process, surface treatments, and proper maintenance contribute to the high resistance of steel channels to corrosion, ensuring their durability and longevity in various applications.

Regular maintenance and inspection of steel channels is also crucial in preventing corrosion, as any damages or breaches in the oxide layer can expose the underlying metal and increase the risk of corrosion. Overall, the combination of the natural passivation process, surface treatments, and proper maintenance make steel channels highly resistant to corrosion, ensuring their longevity and durability in various applications.
Steel channels resist corrosion due to the protective layer formed by the oxidation of iron when exposed to oxygen and moisture in the air. Additionally, steel channels can be galvanized or coated with a corrosion-resistant material, further enhancing their resistance to corrosion.
