Understanding metal thickness is fundamental for engineers, fabricators, designers, and DIY enthusiasts working with aluminum. The gauge system, while common, can be confusing. As a leading supplier of precision aluminum products, Huaxiao-Alloy knows that clarity on specifications like 16 gauge aluminum thickness is critical for selecting the right material for your project.
What is the Actual Thickness of 16 Gauge Aluminum?
The simple, direct answer is:
- 16 gauge aluminum thickness = 0.0508 inches
- 16 gauge aluminum thickness = 1.291 millimeters
Unlike steel gauges, which are standardized within specific systems like US Standard (USS) for sheet metal, aluminum gauges follow a unique scale primarily used for sheet and wire. This is the Aluminum Gauge (AWG – Brown & Sharpe for wire, but extended generally for sheet) system. This means the gauge number refers directly to an actual thickness measured in inches or millimeters.

| 3/16″ (Fractional) | 0.1875 in | 4.763 mm | N/A | N/A |
| 1/16″ (Fractional) | 0.0625 in | 1.588 mm | N/A | N/A |
| .063″ (Decimal) | 0.0630 in | 1.600 mm | N/A | N/A |
(Note: Steel gauges are primarily for reference; aluminum uses its own scale. Fractional and decimal equivalents are included for clarity.)
Why Does Aluminum Have Its Own Gauge Scale?
Historically, gauge systems originated based on the number of times a metal sheet was passed through rolling mills – fewer passes meant thicker metal and a lower gauge number. Over time, formal standards were established. However, different metals developed different standard thicknesses for the same gauge number. The aluminum industry primarily uses the Brown & Sharpe (B&S) or American Wire Gauge (AWG) scale for both sheet and wire, leading to a direct 16 gauge to inch/mm relationship. A 16ga aluminum sheet is NOT the same thickness as 16ga steel sheet. Always verify the material and standard when thickness is critical.
Common Applications of 16 Gauge Aluminum
Due to its excellent balance of strength, formability, and light weight, 16 gauge aluminum sheet finds uses across numerous industries. As a premier supplier, Huaxiao-Alloy provides high-quality 16ga sheets and fabricates components for applications like:
- Transportation: Truck/trailer bodies, aircraft interior panels, boat components, trim pieces.
- Construction: Decorative wall panels, soffits, signage, flashing, gutters (downspouts often use lighter gauges).
- HVAC: Ductwork components (flanges, transitions), protective covers.
- Industrial: Machine guards, tool boxes, shelving components, tank liners, electronic enclosures.
- Consumer Goods: Equipment housings, decorative arts & crafts, backing plates.
- Prototyping: Versatile thickness for functional prototypes across various sectors.
Related Products: 16 Gauge Tubing & More
Gauge is also commonly used for specifying the wall thickness of tubing, though it’s crucial to know the underlying dimension standard (ASTM, etc.). 16 gauge tubing thickness is generally consistent across materials for the wall measurement:
- 16 gauge tube wall thickness ≈ 0.065 inches (1.65 mm). However, square aluminum tubing dimensions are defined by both outer size (like 1×1 aluminum square tubing, 1 1/4 square aluminum tubing, 1 1/2 aluminum square tubing, 3×3 aluminum square tubing) and wall gauge/thickness. Common sizes range from small 1 inch square aluminum tubing to much larger profiles. Understanding aluminum square tube sizes and aluminum rectangular tube dimensions requires knowing O.D. and wall gauge.

A: 1/16 of an inch? Actually, no! While 1/16″ is exactly 0.0625 inches (1.588 mm), 16 gauge aluminum sheet is defined as 0.0508 inches (1.291 mm) thick. Don’t confuse gauge with fractions. 16ga thickness is its own specific measurement.
Steel gauges are thicker for the same number. 16ga steel is approximately 0.0598 inches (1.519 mm), significantly thicker than 16ga aluminum’s 0.0508 inches. Which is thicker 14 or 16 gauge? For aluminum or steel, the answer is always 14 gauge is thicker than 16 gauge, but the actual thickness difference varies between metals. A 16ga steel sheet thickness is closer to a 15ga aluminum sheet than a 16ga.
See the answer to Q1! 16ga aluminum thickness is 0.0508 inches or 1.291 millimeters. Understanding gauge to inches conversion is vital.
Strength depends heavily on the specific aluminum alloy (e.g., 5052-H32 is much stronger than 3003-H14). Generally, 16ga aluminum offers a good balance of strength, formability, and light weight. Refer to the “Common Applications” section above. It’s thicker and stronger than 24 gauge aluminum or 22 gauge aluminum thickness.
Absolutely! Huaxiao-Alloy stocks 16 gauge aluminum sheet in various alloys, widths (including 4×8 sheets), and finishes.

- 1/16″: Exactly 0.0625 inches (1.588 mm). An actual fractional dimension. Sometimes called “0.063 inch nominal”. This is thicker than 16ga.
- .063″: Generally refers to 1/16″ nominal sheet, approx 0.0625″. This is not standard 16ga.
- .060″: Refers to aluminum sheet that is very close to 16 gauge, but not the exact standard. It’s approximately 15 gauge aluminum (0.0571″) to 16 gauge. Requires confirmation. Sometimes sold as “thinner gauge” equivalent. A .060 aluminum sheet falls between 15ga and 16ga.
- 16 Gauge Aluminum: The industry standard thickness 0.0508 inches (1.291 mm).
The AWG scale defines the diameter of solid, round wire. For sheet metal, the gauge number corresponds directly to the AWG wire diameter value translated into a sheet thickness standard. So, 16 gauge aluminium wire diameter and 16ga aluminum sheet thickness are defined by the same underlying scale. However, 16g aluminum wire has its diameter defined, while sheet has its thickness defined.
0.0508 inches is approximately 1/20 of an inch (0.050″), though 0.0508″ is more precise. Do not confuse it with 1/16″ (0.0625″). Knowing gauge thickness to inches accurately is crucial.
