Gauge is the measurement metal manufactures use to determine how thick a piece of metal is.
For example, gauge for aluminum runs from 30 to 3. Ironically, the lower the number, the larger the thickness. So 30 gauge is .0100 inches, and 3 gauge is .2294 inches. The thickness of the aluminum used for our Modern Elite Aluminum Planters ranges from .100 to .250 inches, depending on the project.
