Most usage requirements are to maintain the original appearance of the building for a long time. When determining the type of stainless steel to be selected, the main considerations are the required aesthetic standards, the corrosiveness of the local atmosphere, and the cleaning system to be adopted.
However, other applications are increasingly seeking structural integrity or impermeability. For example, the roofs and side walls of industrial buildings. In these applications, the construction cost of the owner may be more important than aesthetics, even if the surface is not very clean.
The use of 304 stainless steel in a dry indoor environment is quite effective. However, in rural and urban areas, frequent cleaning is necessary to maintain its appearance outdoors. In heavily polluted industrial areas and coastal areas, the surface can be very dirty and even produce rust. But to achieve aesthetic effects in outdoor environments, nickel containing stainless steel needs to be used. Therefore, 304 stainless steel is used for curtain walls, side walls, roofs, and other building purposes, but in highly corrosive industrial or marine atmospheres, 316 stainless steel is used.

People have fully recognized the use of stainless steel in structural applications. Several design criteria include 304 and 316 stainless steel. Because the "dual phase" stainless steel 2205 combines good atmospheric corrosion resistance with high tensile strength and elastic limit strength, it is also included in European standards.
Product shape
In fact, stainless steel is produced in fully standard metal shapes and sizes, and there are also many special shapes. The commonly used products are made of thin plates and strips, and special products are also produced using medium thick plates, such as hot-rolled structural steel and extruded structural steel. And there are also circular, elliptical, square, rectangular, and hexagonal welded pipes or seamless steel pipes and other forms of products, including profiles, bars, wires, and castings.
