In the field of architectural applications, the surface processing of stainless steel is important for many reasons. The corrosive environment requires a smooth surface because the surface is smooth and not easy to deposit. Dirt deposits can rust and even cause corrosion of stainless steel.

　　n the spacious hall, stainless steel is the most commonly used material for elevator decorative boards. Although the fingerprints on the surface can be wiped off, it affects the appearance, so it is best to choose a suitable surface to prevent leaving fingerprints.

　　Hygiene conditions are important for many industries, such as food processing, catering, brewing, and chemical industries. In these applications, the surface must be easy to clean daily, and chemical cleaning agents are often used.

This is a significant feature of stainless steel over aluminum. The surface of aluminum is easy to leave marks and is often difficult to remove. When cleaning the stainless steel surface, it should be cleaned along the stainless steel texture, because some surface processing texture is unidirectional.

　　Stainless steel is best used in hospitals or other areas where sanitary conditions are critical, such as: food processing, catering, brewing, and chemicals. This is not only because it is easy to clean daily, sometimes using chemical cleaning agents, but also because it is not easy to breed bacteria . Tests have shown the same performance in this respect as glass and ceramics.
