Sheet metal workers work with thin metal sheets (up to 3mm thick) which they bend, cut and shape using hammers, small presses, roller machines and guillotines.
Sheet metal workers work with sheet steel, galvanised steel, stainless steel, aluminium, copper, etc. and their work includes the cutting of these metals by using patterns or templates as guides, as well as shaping the metal by forming, bending, beating or rolling by means of manual and CNC (Computer Numerical Control) machinery.
Some sheet metal workers specialise in more complex techniques or in operating one or more of the machines.
Sheet metal workers are usually employed by firms manufacturing such articles as ventilation equipment, catering and food processing equipment, computer and data communications hardware and can also be involved in vehicle manufacture.
