Metallilevyissä

Metallilevyissä refers to sheet metal in Finnish. Sheet metal is a metal that has been processed into thin and flat pieces. It is typically produced by industrial manufacturing processes such as rolling mills. Sheet metal is used in many applications, including automotive bodies, aircraft fuselages, and building roofs. Common types of sheet metal include steel, aluminum, and copper.

Steel sheet metal is widely used due to its strength and affordability. It can be galvanized, meaning it is coated with a protective layer of zinc, to prevent rust and corrosion. This is particularly common in construction and automotive manufacturing. Aluminum sheet metal is lighter than steel and offers good corrosion resistance, making it a popular choice for aircraft, food containers, and roofing. Copper sheet metal, while more expensive, is known for its excellent conductivity and malleability, often used in electrical wiring, plumbing, and decorative applications.

The thickness of sheet metal is measured in gauge, with lower gauge numbers indicating thicker material. Sheet metal can be fabricated using various techniques, such as cutting, bending, stamping, and welding, to create a wide range of products. Its versatility and durability make it a fundamental material in numerous industries.
