Steel Making steel
Today steel is made in huge buildings called 'steel mills', and is most often made by machines. It is a very cheap metal today and is used to make many things. Steel is used to making buildings and bridges, and all kinds of machines. Almost all ships and cars are today made from steel. When a steel object is old, or it is broken beyond repair, it is called 'scrap'. The scrap can be melted down and re-shaped into a new object.
