Comprehensive Guide to Sheet Metal Gauge Sizes
Introduction
The following sheet metal gauge size reference chart gives the weight and thickness of sheet metal given as a “gauge” (sometimes spelled gage) and indicates the standard thickness of sheet metal and wire. For most materials, as the gauge number increases, the material thickness decreases. Understanding gauge sizes is crucial for engineers, manufacturers, and DIY enthusiasts alike.
Technical Features of Sheet Metal Gauges
Sheet metal gauges are essential for determining the thickness of metal sheets. The gauge system is not standardized across different materials, meaning that the same gauge number can correspond to different thicknesses depending on the type of metal. Below is a comparison of the technical features of various gauge systems.
| Feature | Standard Steel | Galvanized Steel | Stainless Steel | Aluminum |
|---|---|---|---|---|
| Gauge 3 | 0.2391 in (6.073 mm) | 0.2391 in (6.073 mm) | 0.2391 in (6.073 mm) | 0.2294 in (5.827 mm) |
| Gauge 10 | 0.1345 in (3.416 mm) | 0.1382 in (3.510 mm) | 0.1406 in (3.571 mm) | 0.1019 in (2.588 mm) |
| Gauge 18 | 0.0478 in (1.214 mm) | 0.0516 in (1.310 mm) | 0.0500 in (1.270 mm) | 0.0403 in (1.024 mm) |
| Gauge 36 | 0.0067 in (0.170 mm) | 0.0070 in (0.178 mm) | 0.0070 in (0.178 mm) | 0.0050 in (0.127 mm) |
Differences in Types of Sheet Metal Gauges
Different types of sheet metal gauges are used for various applications. The most common types include standard steel, galvanized steel, stainless steel, and aluminum. Each type has unique properties that make it suitable for specific uses.
| Type | Material | Common Uses | Advantages |
|---|---|---|---|
| Standard Steel | Carbon Steel | Construction, automotive parts | High strength, cost-effective |
| Galvanized Steel | Steel with Zinc Coating | Roofing, siding, and outdoor applications | Corrosion resistance |
| Stainless Steel | Alloy Steel | Kitchen equipment, medical devices | Corrosion resistance, aesthetic appeal |
| Aluminum | Lightweight Metal | Aerospace, automotive, and packaging | Lightweight, good corrosion resistance |
Understanding Gauge Systems
The gauge system has a long history in metal fabrication, originating from the British wire industry. It is essential to note that gauge numbers do not directly correlate to specific measurements in inches or millimeters. For example, 18 gauge steel measures 0.0478 inches thick, while 18 gauge aluminum measures 0.0403 inches thick. This discrepancy highlights the importance of using a gauge conversion chart.
Applications of Sheet Metal Gauges
Sheet metal gauges are widely used in various industries, including construction, automotive, and manufacturing. For instance, in the automotive industry, different gauge sizes are used for body panels, frames, and other components. Similarly, in construction, gauges are crucial for roofing and siding materials.
Conclusion
Understanding sheet metal gauge sizes is vital for anyone working with metal materials. The differences in gauge systems and the specific applications of various types of sheet metal can significantly impact the quality and durability of the final product.

FAQs
1. What is the difference between gauge and thickness?
Gauge refers to the size of the metal sheet, while thickness is the actual measurement of the sheet’s width. Different materials have different thicknesses for the same gauge number.
2. How do I convert gauge to inches?
You can use a gauge conversion chart to find the equivalent thickness in inches for a specific gauge number. For example, 18 gauge steel is 0.0478 inches thick.
3. Why is galvanized steel used?
Galvanized steel is coated with zinc to prevent corrosion, making it ideal for outdoor applications like roofing and siding.
4. Can I use the same gauge for different metals?
No, the same gauge number can correspond to different thicknesses depending on the type of metal. Always refer to a conversion chart for accuracy.
5. Where can I find more information on sheet metal gauges?
You can visit websites like www.engineersedge.com and www.metalsupermarkets.com for detailed charts and resources on sheet metal gauges.
