The size of a Rectangular Hollow Section (RHS) can vary widely based on the specific requirements of a project or application. RHS comes in a range of sizes in terms of both width (b) and height (h), and it can also vary in wall thickness. Common sizes for RHS can be specified in terms of their dimensions, typically in millimeters (mm).
For example, a commonly used designation for RHS might look like this: RHS 100x50x5, where:
"100" represents the width (b) of the rectangular section in millimeters.
"50" represents the height (h) of the rectangular section in millimeters.
"5" represents the wall thickness (t) in millimeters.
So, in this example, you have an RHS with a width of 100 mm, a height of 50 mm, and a wall thickness of 5 mm. These measurements can be adjusted to meet the specific structural and design requirements of a project. Different sizes and thicknesses of RHS are available to provide the necessary strength and load-bearing capacity for various construction and engineering applications.
