Sheet metal has been around for many centuries, although methods of fabrication have changed as technology has evolved. But what exactly is sheet metal and what is it used for and in which industries?

Sheet Metal and Sheet Metal Fabrication

Sheet metal, as the name suggests, is simply a thin, flat piece of metal. The sheets are made by melting the base metal, then casting and rolling it. The most common base metals that are used are steel, aluminium, copper and brass.

Sheet metal fabrication is essentially the process of making things from sheet metals. There are various methods of doing this, including cutting, punching and bending.

Common Applications/Uses

There is a huge range of common uses for sheet metal, a number of which are outlined below.

• The automotive industry uses sheet metal to construct body panels, frames and other components. Sheet metal provides durability and robustness whilst keeping the weight as low as possible.
• The aerospace industry uses sheet metal for wings, fuselages and engine parts. These require durable yet lightweight materials that are resistant to harsh conditions.
• Appliance manufacturers use sheet metal for the frames and doors of washing machines, fridges/freezers, microwaves and more.
• The construction industry uses sheet metal for roofing, ductwork, external coverings and even staircases. Intricate architectural designs are often also made from sheet metal. Its corrosion-resistance properties mean that it can be used outdoors.
• In the electronics industry, sheet metal is used to create micro parts that are found in smartphones, laptops and computers. These provide electromagnetic shielding, reliable conductivity, structural integrity and heat dissipation.
• In the manufacturing of furniture, sheet metals are used for chairs, tables, shelves, lockers and ornamental furniture. This can be for both aesthetic and functional reasons or both.

Other common products made from sheet metal include HVAC systems and pipes, miscellaneous fixtures and fittings, machine parts and jewellery.
