Sheet metal is a thin sheet of metal used for mechanical constructions such as car bodies, truck tanks, etc.

The sheets are built in various thicknesses, generally from 1 to 12 millimeters, depending on the use and the type of manufacturing it has. Its machining is carried out in stamping and die-cutting presses "Die (cutting)") using punches and dies. Sheet metal is not just metal, but any material that is malleable. To give them greater rigidity, the sheets are often folded forming frets, waves, etc., which increase their inertia.

The elements that are manufactured from metal sheets usually have surface treatments against oxidation and corrosion, such as chrome plating, painting, galvanizing, etc. Tinplate is a type of very thin iron and tin metal sheet that is used to make canning containers.
