Sheet metal

INTRODUCTION

Sheet metal is metal formed by an industrial process into thin, flat pieces. It is one of the fundamental forms used in metalworking and it can be cut and bent into a variety of shapes. Thicknesses can vary significantly; extremely thin thicknesses are considered foil or leaf, and pieces thicker than 6 mm (0.25 in) are considered plate.

Sheet metal is often used in

  1. automobile and truck (lorry) bodies
  2. airplane fuselages and wings
  3. medical tables
  4. roofs for buildings (architecture) etc
