A Circular Hollow Section (CHS), also known as a Circular Hollow Structural Section (CHSS) or simply a round tube, is a type of hollow metal profile that has a circular or cylindrical shape. It is commonly used in structural and construction applications and is made from materials such as steel, stainless steel, or aluminum.
CHS is often used in a wide range of construction and engineering applications where its rounded shape offers certain advantages. Some of the common uses for CHS include:
Poles and Posts: Round tubes are frequently used as posts or poles in various structures, including street lighting, flagpoles, and fencing.
Handrails: CHS is used for constructing handrails in buildings, bridges, and staircases due to its smooth, rounded shape.
Conveyor Systems: In material handling and conveyor systems, circular hollow sections are employed as conveyor rollers and framework.
Mechanical Components: CHS can be used as a structural element in machinery and equipment, providing strength and stability.
Building Columns: Round columns are sometimes used in building construction to support heavy loads and provide architectural aesthetics.
