Stainless steel is classified as a high-quality alloy steel due to its composition, which includes more than 8% of various elements. In the case of stainless steel round tubes, they are protected on the outside by a thin layer of chromium. This protective layer ensures that the internal environment of the stainless steel round tube remains unaffected and undamaged by the external environment.
Stainless steel round tubes offer several advantages, including corrosion resistance, high strength, durability, 100% recyclability, environmental friendliness, sustainability, and easy maintenance.

Stainless steel square tube is a type of hollow, long strip steel with a square cross-section. It is named square tube due to its square-shaped cross-section. Based on the cross-sectional shape, it can be further divided into square tubes and rectangular tubes. Stainless steel square tubes are classified into two categories: seamless steel tubes and welded steel tubes (also known as seamed tubes).
