@ HF4 - Belgium.
 
Haut Fourneau 4, commonly known as just HF4 was part of the Cockerill-Sambre steel works, a vast industrial site in Belgium. Steel has been produced at the site since the early 1800’s. The blast furnace was used for smelting iron ore, and was the major technique used for the production of steel at the time.
The iron and steel produced at HF4 was mainly used for car production, an industry that almost collapsed in 2008.
 
Production at the steel works was halted and the plant placed on standby. The facility was sold to another company, however production was never restarted and in 2012 the site was closed down after a failed merger.
