Aluminum coil stock is available in a range of gauge thicknesses, which are commonly measured in terms of “gauge” or “mil.” The gauge system is used to indicate the thickness of metal sheets or coils, where a higher gauge number corresponds to a thinner sheet. The mil system is another measurement of thickness, where 1 mil is equal to 0.001 inches.

The specific gauge thickness of aluminum coil stock can vary depending on the intended application and the supplier. However, here are some common gauge thicknesses for aluminum coil stock:

0.019″ or 0.020″ gauge: This is a thinner gauge often used for residential roofing and siding.

0.024″ or 0.025″ gauge: Slightly thicker than the previous gauge, commonly used for residential roofing and other applications.

0.032″ gauge: This gauge is often used for gutters, fascia, and other exterior trim applications.

0.040″ gauge: A bit thicker and suitable for applications that require a more robust material, such as commercial roofing.

0.050″ gauge: Used in applications where increased strength and durability are necessary, such as industrial roofing and architectural features.

Thicker gauges (e.g., 0.063″, 0.080″, 0.125″): These thicker gauges are often used for heavy-duty applications like structural components and industrial equipment.
