Iron & Steel

Steel is the world’s most important engineering and construction material. It is used in every aspect of our lives; in cars and construction products, refrigerators and washing machines, cargo ships and surgical scalpels. It can be recycled over and over again without loss of property.

Steel is not a single product. There are more than 3,500 different grades of steel with many different physical, chemical, and environmental properties.

Approximately 75% of modern steels have been developed in the past 20 years. If the Eiffel Tower were to be rebuilt today, the engineers would only need one-third of the steel that was originally used.
Modern cars are built with new steels that are stronger but up to 35% lighter than in the past
