What is 20 gauge aluminum sheet

20 gauge aluminum sheet refers to the thickness of the aluminum sheet, specifically in the United States. It is equivalent to 0.0320 inches or 0.812 millimeters. This thickness is commonly used for lightweight applications such as crafting, roofing, and flashing.

20 gauge aluminum sheet

In the context of sheet metal, “gauge” refers to the thickness of the metal. The gauge number typically decreases as the thickness of the metal increases. For example, a 20 gauge aluminum sheet is thinner than an 18 gauge sheet. The gauge system is used to provide a standard measurement for the thickness of various metals, including aluminum, steel, and others.

Properties and characteristics of 20 gauge aluminum sheets

20 gauge aluminum sheets have several properties and characteristics:

  • 1. **Lightweight:** Aluminum is a lightweight metal, making 20 gauge sheets easy to handle and install compared to other materials like steel.
  • 2. **Corrosion-resistant:** Aluminum naturally forms a protective oxide layer, which helps prevent corrosion, making it suitable for outdoor applications.
  • 3. **Ductile:** Aluminum is relatively ductile, meaning it can be easily formed into various shapes without cracking.
  • 4. **Conductive:** Aluminum is a good conductor of electricity, making it suitable for applications where electrical conductivity is required.
  • 5. **Reflective:** Aluminum has a high reflectivity for both visible and radiant heat, making it suitable for applications where heat reflection is important, such as in roofing materials.
  • 6. **Recyclable:** Aluminum is highly recyclable, making it an environmentally friendly material choice.
  • 7. **Non-magnetic:** Aluminum is non-magnetic, which can be advantageous in certain applications.

Overall, 20 gauge aluminum sheets are versatile and commonly used in a wide range of applications, including roofing, siding, automotive parts, and craft projects, among others.
