Sheet Metal

What is sheet metal?

Sheet metal is a metal that is shaped into thin, flat pieces by hot and cold rolling industrial process. Sheet metal is one of the basic forms of metalworking and can be cut and bent into various shapes.

How is sheet metal made?

Sheet metal is made by running hot slabs of metal through a series of roughing rolling stands that makes them thinner and longer. To make them even thinner, these sheets go through finishing rolling stands and are then cooled and rolled into coils.

What are the different types of sheet metal finish?

Sheet metal coils after hot rolling and pickling can be used as what is known as a hot band. If special finishing is needed, further processing is done starting with cold rolling to make the sheets even thinner. After that, the sheet metal coils can go through other finishing processes.

• Galvanising is the process of zinc coating the steel sheets for corrosion resistance

• Tinning is the process of tin coating the steel sheets for food cans

• Anodising is used for aluminium to create a thicker protective oxide layer

• Annealing is used to make the metal sheets easier to bend and form

• Tempering is used to add hardness and create surface textures in the metal sheets using special rollers
