Iron & Steel Production (NACE codes: C24.1, C24.2, C24.3)

General Information about the sector

The steel industry has long held a strategic place in the EU economy, fostering innovation, growth, and employment (According to EC, Raw materials, metals, minerals and forest-based industries, Metal industries, The EU steel industry, 2018.). Iron and steel have found uses in agriculture, construction, in the generation and distribution of power, in the manufacturing of machinery and equipment, in household and in medicinal uses. In 2006 steel production increased up to a world total of more than 1200 million tonnes (Best Available Techniques (BAT) Reference Document for Iron and Steel Production, 2013).
