How is structural tubing typically sized?

Structural tubing is typically sized using both outside diameter (OD) and wall thickness. This method is essential because the strength and load-bearing capacities of the tubing are influenced by these two measurements. The outside diameter gives a complete understanding of the overall size of the tube, while the wall thickness is crucial for determining the structural integrity and how much weight or stress the tubing can withstand without failing.

This dual measurement approach is critical in various applications such as construction and manufacturing, where specific tolerances and load requirements must be met. By specifying both the OD and wall thickness, engineers and builders can ensure that they are selecting the appropriate tubing for the intended application, leading to safer and more effective structural designs.
