If you have scrap metal around the premises then using a scrap metal collection service will help you with sending it for recycling. They will come sort out the metals for you and handle the transport to the relevant recycling centres.
Scrap metals are separated into two categories, namely non-ferrous and ferrous. Non-ferrous metals do not contain iron, are lightweight and non-magnetic and are generally higher in value to ferrous metals. Aluminium, copper, brass, tin, lead and zinc are some examples of non-ferrous metals. Ferrous metals are stronger as they contain iron with carbon steel, steel and cast iron being some examples.
