Hollow section refers to a cross-section shape with a hollow structure, usually used in components or structures made of metal, plastic, concrete, etc. The cross-section can be square, rectangular, circular or other shapes.
A “Steel hollow section” specifies that the section is made of steel. It has the properties of steel, such as high strength, stiffness and corrosion resistance.

The term “Hollow Section” (HSS: Hollow Structural Section) refers to welded steel tube that is utilized as structural elements in buildings and other structures, as well as a variety of manufactured items. It is commonly manufactured using hot-rolled coils. Slitting the coils to the appropriate width for the manufactured portion and then shaping them to the final shape required. Following size formation and seam welding, the tube is cut to the necessary length to make a single piece of pipe.
Hollow structural section is a low-cost, lightweight material that is easy to weld, mold, punch, and drill. Its hollow design covers and protects wires, pipelines, and moving parts but allows them to be exposed. Additionally, it can be substituted for solid steel goods such as I-Beams and Wide Flange.

The roll forming process is used to produce hollow tube for construction projects. The coil is continually twisted by the forming rollers and then shaped into circular hollow sections and finally square hollow sections and rectangular hollow sections.
In welded steel frames and columns, hollow structural section are often employed. Because of their enormous strength, they are also frequently employed as steel support beams. Especially rectangular sections are frequently utilized in welded steel frames when components are subjected to loading from several directions. Because they have identical geometry along two or more cross-sectional axes and consequently uniform strength properties, square and circular hollow sections are extremely effective forms for this multiple-axis loading. This makes them suitable for columns. They are also extremely torsion-resistant.
Square hollow section (SHS) is another popular type of structural steel pipe that falls somewhere between RHS and CHS in terms of characteristics, appearance, and structural behavior. SHS has a flat surface that makes joining and welding easier.
Rectangular hollow sections (RHS) are a frequently used material in mechanical, structural, and construction applications. This is because the flat surface of the pipe results in a more economical structural solution for joining and various other types of fabrication work.
Circular hollow sections (CHS) are frequently used in a variety of structural, mechanical, and construction applications.
CHS is a popular architectural choice for aesthetic appearances in a variety of applications.
Any steel construction with hollow sections gains strength and attractiveness. Employing hollow sections for building and structural purposes has various advantages over using W-beams:
