Did you know that a lot of the stuff you see every day is made with aluminum? A lot of important things people use every day are made from aluminum, and that requires professional aluminium extruders to work with aluminum alloys to make exactly what they have to make.
Aluminum coils are one of the most commonly used things that have to do with aluminum. There are a whole bunch of factory and wholesale companies that are aluminum scrap suppliers, and those scraps of aluminum eventually become important things, like pieces in your cell phone and parts of your toaster. Without them, life would be a lot different.
