Sheet metal is a versatile material used for a wide range of applications. It is a thin, flat metal sheet that is easy to shape and bend. However, it is often referred to by different names, depending on the context and industry in which it is used. Some of the synonyms for sheet metal include plate metal, metal plate, metal sheet, thin metal, and cold-rolled steel. Other terms like stainless steel, aluminum, tin, and brass are also used when referring to sheet metal made of specific metals. Each of these terms may be used interchangeably, but it's essential to understand the differences between them when selecting the right material for a specific purpose.
