Steels that are open at both ends and have a hollow section, and whose length is larger than the circumference of the section, can be called steel pipes. When the length is small compared to the perimeter of the section, it can be called a pipe section or a tubular fitting, which are all in the category of pipe products.
For more than sixty years, architects have used stainless steel to build cost-effective permanent buildings. Many existing buildings fully illustrate the correctness of this choice. Some are very entertaining, such as the Chrysler Building in New York City. But in many other applications, the role of stainless steel is not so compelling, but it plays an important role in the aesthetics and performance of buildings. For example, since stainless steel is more wear resistant and indentation resistant than other metal materials of the same thickness, it is the material of choice for designers when constructing sidewalks in places with large population movements.
Stainless steel has been used for more than 70 years to build new buildings and structural materials used to repair historical sites. Early designs were calculated according to basic principles. Today, design specifications, such as the American Society of Civil Engineers' standard ANSI/ASCE-8-90 "Design Specification for Cold Formed Stainless Steel Structural Parts" and the "Structural Stainless Steel Design Handbook" jointly published by NiDI and Euro Inox, have simplified service life. The design of structural components for good integrity.
