ArcelorMittal Belgium has announced that it has officially restarted its Galva 5 hot dip galvanizing line in Flémalle after four years of inactivity. The reopening strengthens the company’s industrial footprint in Europe and expands its production capabilities for metallic-coated steel products in thicker gauges.
Major modernization program completed
The Galva 5 line was acquired by ArcelorMittal in July 2025, after which the company launched an extensive refurbishment and modernization project.
The upgrades included roof renovations, maintenance work on coil feeding and uncoiling systems, restoration of the pickling section and zinc bath, and improvements to the site’s digital infrastructure.
Expanded coated steel production capabilities
With the restart of Galva 5, ArcelorMittal Belgium regains domestic production capacity for metallic-coated steel in thicker formats. The facility is integrated into the company’s broader European coated steel network and processes hot rolled coils supplied from ArcelorMittal’s Ghent plant.
The galvanized steel products produced at the Flémalle site are intended for several industrial applications, including road safety infrastructure, HVAC systems, industrial equipment, and automotive components. According to the company, the facility’s location in central Europe will improve proximity to customers and support shorter lead times and greater supply flexibility.
Advanced technical specifications
Technically, the Galva 5 line is capable of processing hot rolled substrates up to 6.35 mm thick and 1,880 mm wide. The facility also includes in-line pickling technology, enabling shorter production routes and compatibility with high-strength steels and various metallic coatings.
ArcelorMittal Belgium stated that the restart of the line also supports the company’s lower-carbon steel solutions strategy.
