The surface treatment of stainless steel is very important in the field of architectural applications. The corrosive environment requires a smooth surface because it is not easy to scale. The deposition of dirt will rust stainless steel, and even cause corrosion. In the spacious hall, stainless steel is the most commonly used material for elevator decoration board, although the fingerprint on the surface can be erased, but the effect is beautiful, so it is best to choose the right surface to prevent leaving fingerprints. Sanitary conditions are important in many industries, such as food processing, catering, brewing and chemicals, where surfaces must be easy to clean on a daily basis, often using chemical cleaners. Stainless steel is the best material. In public places, the surface of stainless steel is often painted, but one of its important properties is that it can be washed off, which is a significant feature of stainless steel over aluminum. Aluminum leaves marks on its surface, which are often difficult to remove. Cleaning stainless steel surface should be cleaned along the stainless steel lines, because some surface processing lines are one-way. Stainless steel is most suitable for hospitals or other health conditions more critical areas, such as: food processing, catering, wine and chemicals, not only because it is easy to clean every day, sometimes using chemical cleaning agents, but also because it is not easy to breed bacteria. The test shows that the performance in this respect is the same as glass and ceramics.
