Heavy industry has always been a motor of the economy and the driving force behind industrialisation.
The steel industry manufactures preliminary products such as hot wide strip, forged parts, metal sheets, rails, long products, wire and pipes.
These are then processed into end products.
In the complete manufacturing process, distinction is made between "cold" materials such as scrap, pipes, coils or ingots and "hot" products such as molten steel in slag pots.
