Sheet metal fabrication is the process of transforming flat sheets of metal into various shapes and structures. This is achieved through techniques such as cutting, bending, and assembling. Common materials used include aluminum, steel, and copper, which are chosen based on their strength, weight, and resistance to corrosion. The fabricated metal products can be found in numerous applications, from automotive parts to building components. The process often involves the use of specialized machinery, such as laser cutters and press brakes, to ensure precision and efficiency in creating the desired shapes and sizes.
