Sixteen-gauge aluminum is 0.0508 inches thick. It is slightly thinner than standard steel and galvanized steel in terms of gauge.
In commercial settings, the thickness of 16-gauge aluminum is often referenced only to the third decimal point. In other words, it might be considered 0.051 as the industry standard. Additionally, unlike other types of sheet metal, aluminum is frequently sold based on its thickness rather than its gauge because of international standards.
Aluminum is used extensively in engineering, construction and other industries. Its resistance to salt water corrosion makes it a popular material in marine applications, and its lightweight construction lends itself to aircraft engineering.
