Most stainless steel heads are required to maintain the original appearance of the building for a long time. When determining the type of stainless steel to be used, the main consideration is the required aesthetic standards, the corrosion of the local atmosphere and the used cleaning system. However, other applications increasingly seek only structural integrity or impermeability. For example, roofs and side walls of industrial buildings. In these applications, the owner's cost of construction may be more important than aesthetics. It is acceptable that the surface is not very clean. 430 stainless steel works well in dry indoor environments. However, to maintain their appearance outdoors in both rural and urban areas, frequent cleaning is necessary. In heavily polluted industrial areas and coastal areas, surfaces will be dirty or even be corroded or rusted. If want the aesthetic effect in the outdoor environment, it is necessary to adopt nickel-containing stainless steel. So, stainless steel head 304 stainless steel is widely applied to curtain wall, side wall, housetop and other engineering, but in the industry with serious corrosiveness or Marine atmosphere, 316 stainless steel is preferred.

Now, the advantages of using stainless steel in structural applications have been fully recognized. Several design guidelines have included 304 and 316 stainless steel. Because the "two-phase" stainless steel 2205 combines good resistance to atmospheric corrosion with high tensile and elastic strength, it is also included in the European standard. In fact, about the shape of the product, stainless steel is manufactured by full standard metal shapes and sizes, and also there are many special shapes. The most commonly used products are made of sheet and strip steel, and special products are also made of medium and heavy plates. For example, the production of hot rolled structural steel and extrusion structural steel.There are also round, oval, square, rectangular and hexagonal welded or seamless steel tubes and other forms of products, including profiles, bars, wires and castings.
