Steel tubes can be called steel tubes, which have hollow sections with openings at both ends, and whose length is larger than the circumference of the section. When the ratio of length to section circumference is small, it can be called pipe section or pipe fittings, which belong to the category of pipe products.

 

For more than 60 years, architects have been using stainless steel to build cost-effective permanent buildings. Many existing buildings fully illustrate the correctness of this choice. Some are very ornamental, such as Chrysler Tower in New York City. But in many other applications, the role of stainless steel is not so noticeable, but it plays an important role in the aesthetics and performance of buildings. For example, because stainless steel has more wear resistance and indentation resistance than other metal materials of the same thickness, it is the preferred material for designers when building sidewalks in places with large population flow.

 

Stainless steel has been used for more than 70 years as a structural material for building new buildings and restoring historic sites. Early designs were based on basic principles. Today, design specifications, such as ANSI/ASCE-8-90 Code for Design of Cold Formed Stainless Steel Structures and NiDI and Euro Inox's Design Manual for Stainless Steel Structures, have simplified the design of building structural components with long service life and good integrity.
