This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If joined into continuous duct assemblies
Assembled structures classify as steel-like ducting even if aluminum.
If thin-walled tubing variety
Wall thickness and pressure specs determine tube vs profile.
