Sheet metal, simply defined, can be said to be metal that has been made into thin and flat pieces. It is obtained by passing thick plates between rollers, that is, by rolling. After the first hot rolling, cold rolling is done to obtain a smooth surface. These sheets with different thicknesses are cut within certain standard sizes or in strips. This process is done with two rollers. It is one of the basic forms used in metalworking. It can be cut and bent into various shapes. It is used in many fields. It can be produced in extremely thin thicknesses. It can be used in flat pieces or as spiral strips (rolls or coils). When it comes to sheet metal, steel sheet is usually thought of, but the concept of sheet is used in other metals.
