Sheet metal comes in different sizes. Generally, not all sheet metal is cut to size. Therefore, depending on your unique application needs, you may need to cut your sheet metal to fit the size you need. Metal sheets typically come in many options, and aluminium sheets are the standard options you will find. They are lightweight, corrosion-resistant and versatile with high thermal conductivity, among other desirable properties. However, like other sheet metals, cutting aluminium can be challenging, especially if you are doing it for the first time.
