1、 Application of stainless steel in building decoration industry

（1） Application scope of stainless steel in building decoration industry

The application of colored stainless steel in architectural decoration is very extensive, almost everywhere. Its main application range is: kitchen equipment, kitchen and bathroom appliances, stainless steel cabinets, counters, escalator handrails, corridor railings, hall pillars, glass door frames and handles, revolving doors, automatic doors, shopping malls, walls and curtain walls, etc.

Stainless steel is most suitable for hospitals or other areas where sanitary conditions are crucial, such as food processing, catering, brewing and chemical industry. This is not only because it is easy to clean every day, sometimes chemical cleaning agents are used, but also because it is not easy to breed bacteria. The results show that the properties of stainless steel are the same as those of glass and ceramics.

（2） Advanced surface processing technology of stainless steel

In the field of building application, the processing of stainless steel is important for many reasons. Corrosion environment requires smooth surface because the surface is smooth and not easy to scale. The deposition of dirt can cause stainless steel to rust and even corrode.

By adopting advanced processing technologies such as cutting, stamping, bending, folding, occluding forming, argon arc welding and plasma cutting, the stainless steel can be made into various shapes of products with clear and smooth surface, without quality defects caused by drilling, welding and riveting.

The increasing market demand of stainless steel products is not only related to the advanced processing technology of stainless steel, but also directly related to the advanced surface treatment technology of stainless steel.

Stainless steel has five main surface processing processes: rolling surface processing, mechanical surface processing, chemical surface processing, reticulated surface processing and color surface processing. Stainless steel has a variety of surface processing technology to broaden its application. Different surface processing makes the surface of stainless steel different, so it has its own characteristics in application.

Stainless steel does not rust because of the inert chromium oxide film on its surface. Because stainless steel takes advantage of this always existing film, it does not fade and does not need to be maintained as often as paint.

What needs to be specially explained here is a special surface processing technology of stainless steel - color processing technology is to use this film to form a specified color.

The color stainless steel can be shaped, even in the sharp bend will not have any adverse effect on the color, and the test shows that the corrosion resistance is enhanced after using this process.

Using vacuum coating ray process and etching process on the surface of stainless steel products, titanium can also be ion sprayed on the metal surface to form decorative gold plate with gold imitation, five colors, bright etching color and glittering, which overcomes peoples impression of single color of stainless steel in the past and expands its application scope.
