Car Body Sheet Metal Gauge
What is Sheet Metal Gauge?
Sheet metal gauge (SMG) is a measure of the thickness of sheet metal. It is expressed as a number, with a higher number indicating a thinner material. For example, 18 gauge sheet metal is thinner than 16 gauge sheet metal.
SMG vs. Thickness
The following table shows the relationship between SMG and thickness:
| SMG | Thickness (inches) |
|---|---|
| 18 | 0.0478 |
| 19 | 0.0418 |
| 20 | 0.0359 |
| 21 | 0.0324 |
| 22 | 0.0289 |
| 23 | 0.0253 |
| 24 | 0.0220 |
| 25 | 0.0189 |
| 26 | 0.0159 |
| 27 | 0.0142 |
| 28 | 0.0126 |
Uses of Sheet Metal in Cars
Sheet metal is used in a variety of applications in cars, including:
- Body panels
- Hoods
- Trunks
- Fenders
- Bumpers
- Exhaust systems
Factors Affecting Sheet Metal Thickness
The thickness of the sheet metal used in a car depends on a number of factors, including:
- The strength required
- The weight of the vehicle
- The cost of the material
- The availability of the material
Conclusion
Sheet metal gauge is an important factor to consider when choosing materials for car body construction. The thickness of the sheet metal used will affect the strength, weight, cost, and availability of the vehicle.
