FAQ:

Q1: How do we guarantee the quality of our products?

A1: We have established an advanced quality management system which conducts strict quality tests at every step, from raw materials to the final product. At the same time, we provide extensive follow-up service assurances as required.

Q2: What makes stainless steel stainless?

A2: Stainless steel must contain at least 10.5 % chromium. It is this element that reacts with the oxygen in the air to form a complex chrome-oxide surface layer that is invisible but strong enough to prevent further oxygen from "staining" (rusting) the surface. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum enhance this surface layer and improve the corrosion resistance of the stainless material.

Q3: Can stainless steel rust?

A3: Stainless does not "rust" as you think of regular steel rusting with a red oxide on the surface that flakes off. If you see red rust it is probably due to some iron particles that have contaminated the surface of the stainless steel and it is these iron particles that are rusting. Look at the source of the rusting and see if you can remove it from the surface.

Q: How do steel channels resist corrosion?: 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.
