How do sheet metal and plate metal differ?

The correct distinction between sheet metal and plate metal is that sheet metal is typically under 1/4 inch thick. This thickness specification is important because it defines the categories based on the gauge of the metal. Sheet metal usually ranges from very thin materials, often used in applications such as ductwork, automotive parts, and appliances, while plate metal is thicker and used in more load-bearing applications like structural components and heavy machinery.

Understanding this thickness difference is essential for selecting the appropriate material for specific applications, ensuring the durability and functionality of the finished product. The classification into sheet and plate metal helps metalworkers and engineers decide on the correct fabrication methods and tools to use for their projects, which is critical in the sheet metal industry.
