What is the difference between aluminium sheet and plate?

The main difference between aluminum sheet and plate lies in their thickness. While both are flat, rectangular pieces of aluminum, sheet metal is generally considered to be less than 6 mm thick, while plates are typically 6 mm or thicker. This distinction is not based on a strict standard and can vary depending on the industry and country.

Sheet metal is often used for lightweight applications that require flexibility, such as in roofing, signage, and automotive panels. It is easily formed and can be cut into various shapes.

On the other hand, aluminum plates are used for applications that require higher strength and durability, such as in structural components, aerospace parts, and heavy-duty machinery. Plates are often machined or fabricated into specific shapes or structures.
