The different gauges of metal studs used in construction typically range from 10 gauge (thickest) to 20 gauge (thinnest), with specific thicknesses measured in mils.
Here's a breakdown of common metal stud gauges and their corresponding thicknesses (in mils):
- 10 Gauge: 118 mils (approximately 0.118 inches) - Heaviest gauge, used for load-bearing walls.
- 12 Gauge: 97 mils (approximately 0.097 inches) - Used in structural applications.
- 14 Gauge: 68 mils (approximately 0.068 inches) - Common for load-bearing walls.
- 16 Gauge: 54 mils (approximately 0.054 inches) - Suitable for non-load-bearing walls and some load-bearing applications.
- 18 Gauge: 43 mils (approximately 0.043 inches) - Typically used for non-load-bearing interior walls.
- 20 Gauge: 33 mils (approximately 0.033 inches) - Lightest gauge, primarily for non-structural interior partitions.
The gauge number indicates the thickness of the steel; a lower gauge number signifies a thicker, stronger stud. Thicker gauges, like 10 and 12, are used in structural applications where they need to bear significant loads. Lighter gauges, like 18 and 20, are typically used for interior, non-load-bearing walls. The selection of the appropriate gauge depends on the structural requirements of the wall and local building codes.
