Hollow structural sections typically come in three main forms: rectangular hollow sections (RHS), square hollow sections (SHS) and circular hollow sections (CHS). Each type of hollow section has its benefits, properties, and purposes.
Circular Hollow Sections
The circular hollow sections (CHS) were the first type of hollow structural section ever made. CHS is commonly used in building, mechanical, and structural purposes. They have clean and consistent lines, enhanced smoothness, and a lack of sharp or protruding edges.
Rectangular Hollow Sections
RHS is also commonly used in building, mechanical, and structural purposes. However, they differ from CHS with their flat surfaces. As a result, RHS may be the more structurally sound and economical choice for some construction applications.
This is especially true in applications where there is a need for extensive joining and welding. RHS can also be used for architectural aesthetics due to its sleek form and clean shape.
Square Hollow Sections
SHS are considered the middle-man between RHS and CHS in terms of mechanical properties, aesthetics, and structural behavior. They feature a flat surface that requires little to no edge preparation, and is ideal for joining and welding.
SHS also features a symmetrical appearance similar to that of a CHS. At times, SHS is the ideal choice, as it provides an ideal balance between strength, functionality, and aesthetic appeal for applications that require all three aspects.
